Read and follow all safety instructions in this manual precisely to avoid unsafe operating
conditions, property damage, personal injury, or death.
Safety symbols in this manual

Indicates an imminently hazardous situation which, if not avoided, will result in severe injury or
death.

Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.

Indicates a potentially hazardous situation which, if not avoided, could result in minor injury or
property damage.

Safety information

• Do not open the cover of the equipment while it is on or operating. Likewise, do not operate the
inverter while the cover is open. Exposure of the high voltage terminals or the charging area to
the external environment may result in an electric shock. Do not remove any covers or touch
the internal circuit boards (PCBs) or electrical contacts on the product when the power is on or
during operation. Doing so may result in serious injury, death, or serious property damage.
• Do not open the cover of the equipment, even when the power supply to the inverter has been
turned off, unless it is necessary for maintenance or regular inspection. Opening the cover may
result in an electric shock even when the power supply is off.
• The equipment may hold a charge long after the power supply has been turned off. Use a
multi-meter to make sure that the remaining voltage is below 30 VDC before working on the
inverter, motor, or motor cable.

iii

Safety Information

• This equipment must be grounded for safe and proper operation.
• Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the
power supply and have the inverter professionally repaired.
• The inverter becomes hot during operation. Avoid touching the inverter until it has cooled to
avoid burns.
• Do not allow foreign objects, such as screws, metal chips, debris, water, or oil, to get inside the
inverter. Allowing foreign objects inside the inverter may cause the inverter to malfunction or
result in a fire.
• Do not operate the inverter with wet hands. Doing so may result in electric shock.

• Do not modify the interior workings of the inverter. Doing so will void the warranty.
• Do not use cables with damages or cracks on the protective insulation when wiring the inverter.
Damaged insulation may cause misoperation, an electric shock or a fire.
• Do not place heavy objects on top of electric cables. Doing so may damage the cable and result
in an electric shock.

Note
The maximum allowed prospective short-circuit current at the input power connection is defined in
IEC 60439-1 as 100 kA. The drive is suitable for use in a circuit capable of delivering not more than
100 kA RMS at the drive’s maximum rated voltage.

3 Installing the Inverter

3.1 Installation Considerations
Inverters are composed of various precision electronic devices, and therefore the installation
environment can significantly impact the lifespan and reliability of the product. The table below
details the ideal operation and installation conditions for the inverter.
Items Description

Ambient Temperature*

CT load (heavy duty): -10℃–50℃
VT load (normal duty): -10℃–40℃
IP54 model types: -10℃–40℃
Ambient Humidity 90% relative humidity (no condensation)
Storage Temperature - 4–149F (-20–65℃)
Environmental Factors dAn environment free from corrosive or flammable gases, oil residue, or

ust (pollution degree 2)
Altitude/Vibration Lower than 3,280 ft (1,000 m) above sea level/less than 0.6 G (5.9
m/sec2)
Air Pressure 70–106 kPa
* The ambient temperature is the temperature measured at a point 2” (5 cm) from the surface of the
inverter. No ice or frost should be present.

• Do not transport the inverter by lifting with the inverter’s covers or plastic surfaces. The inverter
may tip over if covers break, causing injuries or damage to the product. Always support the
inverter using the metal frames when moving it.
• Hi-capacity inverters are very heavy and bulky. Use an appropriate transport method that is
suitable for the weight. Do not place heavy objects on top of electric cables. Doing so may
damage the cable and result in an electric shock.
• Do not install the inverter on the floor or mount it sideways against a wall. The inverter must be
installed vertically, on a wall or inside a panel, with its rear flat on the mounting surface.

Installing the Inverter

17

Do not allow the ambient temperature to exceed the allowable range while operating the inverter.

3.2 Selecting and Preparing a Site for Installation
When selecting an installation location, consider the following requirements:
• The inverter must be installed on a wall that can support the inverter’s weight.
• The location must be free from vibration. Vibrations can adversely affect the operation of
the inverter.
• The inverter can become very hot during operation. Install the inverter on a surface that is
fire resistant or flame retardant with sufficient clearance around the inverter to allow for
air circulation. The illustrations below detail the required installation clearances.

Install the inverter on a non-flammable surface, and do not place flammable material near the
inverter. Otherwise, a fire may result.

Note
Model types with capacities of 30 kW or more require a minimum of 8” clearance above and below
the unit.

Installing the Inverter

19

• Ensure that the cable conduits do not obstruct the air flow to and from the cooling fan.

• Ensure sufficient air circulation is provided around the inverter when it is installed. If the
inverter is to be installed inside a panel, enclosure, or cabinet rack, carefully consider the
position of the inverter’s cooling fan and vents. The cooling fan must be positioned to
efficiently dissipate the heat generated by the operation of the inverter.

Note
In order to meet EMC standards, 200 V, 30–75 kW model types and model types with capacities of 90
kW or more should be installed inside a metal cabinet.

Installing the Inverter

20

• If you are installing multiple inverters of different ratings, provide sufficient clearance to
meet the clearance specifications of the larger inverter. The iS7 inverters rated for up to 30
kW may be installed side by side.

ESD (Electrostatic discharge) from the human body may damage sensitive electronic components on
the PCB. Therefore, be extremely careful not to touch the PCB or the components on the PCB with
bare hands while you work on the I/O PCB.

To prevent damage to the PCB from ESD, touch a metal object with your hands to discharge any
electricity before working on the PCB, or wear an anti-static wrist strap and ground it on a metal
object.

4.1 Removing the Front Cover for Cable Connection

4.2 Activating and Deactivating the Built-in EMC
Filter
Some iS-7 inverter models have built-in EMC filters to reduce conductive and radiational noise
at the inverter input. Refer to 1.1.1 Identifying the Product on page 1 and check your inverter’s
model type and specifications to see if it has a built-in EMC filter.
If your inverter has a built-in EMC filter, refer to the following instructions to activate or
deactivate it.

Do not activate the EMC filter if the inverter uses a power source with an asymmetrical grounding
structure, for example a grounded delta connection. Personal injury or death by electric shock may
result if the power source is not grounded properly.

4.2.1 Up to 7.5 kW Inverters
1 Locate the plastic knockout cap that covers the EMC filter switch (jumper SW1).

2 Remove the knockout cap and locate the jumper switch. The EMC filter will be deactivated
if the two jumper pins are not connected.

Connecting the Cables

53

3 Connect the two jumper pins using a short circuit connector to activate the EMC filter.

4 To remove the short circuit connector and deactivate the EMC filter, pull the connector
while pressing the latch on the side of the connector. Use pliers or tweezers if you cannot
reach the latch with your fingers.

Connecting the Cables

54

4.2.2 11–22 kW Inverters
1 Locate the EMC filter cable and the ground terminal at the bottom of the inverter.

The EMC filter is deactivated if the EMC filter cable is connected to the insulated stud.


2 Remove the EMC filter cable from the insulated stud and connect it to the ground terminal
(metal) to activate the EMC filter.

An EMC filter prevents electromagnetic interference by reducing radio emissions from the
inverter. Using an EMC filter is not always recommended, as it increases current leakage. If an
inverter uses a power source with an asymmetrical grounding connection, the EMC filter must
be turned off.
Before using the inverter, confirm the power supply’s grounding system. Disable the EMC filter
if the power source has an asymmetrical grounding connection.

4.3 Precautions for Wiring the Inverter

• Do not connect power to the inverter until installation has been fully completed and the inverter
is ready to be operated. Doing so may result in electric shock.
• Wiring and inspection of wiring must be performed by an authorized engineer.

• Install the inverter before connecting the cables.
• Ensure that no metal debris, such as wire clippings, remain inside the inverter. Metal debris in
the inverter can cause inverter failure.
• Power supply cables must be connected to the R, S, and T terminals. Connecting power cables
to other terminals will damage the inverter.
• Use insulated ring lugs when connecting cables to R/S/T and U/V/W terminals.
• The inverter’s power terminal connections can cause harmonics that may interfere with other
communication devices located near the inverter. To reduce interference, the installation of
noise filters or line filters may be required.
• To avoid circuit interruption or damaging connected equipment, do not install phase-advanced
condensers, surge protection, or electronic noise filters on the output side of the inverter.
• To avoid circuit interruption or damaging connected equipment, do not install magnetic
contactors on the output side of the inverter.
• Make sure that the total cable length does not exceed 495 ft (150 m). For inverters < = 3.7 kW capacity, ensure that the total cable length does not exceed 165 ft (50 m). Long cable runs can cause reduced motor torque in low frequency applications due to voltage drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may trigger over-current protection devices or result in the malfunction of equipment connected to the inverter. • Route the signal cables away from the power cables. Otherwise, signal errors may occur due to electric interference. • Tighten terminal screws to their specified torques. Loose terminal block screws may allow the cables to disconnect and cause a short circuit or inverter failure. Refer to 4.7 Specifications of the Power Terminal Block and Exterior Fuse on page 6666 for torque specifications. • Do not place heavy objects on top of electric cables. Heavy objects may damage the cable and result in electric shock. • Use cables with the largest cross-sectional area, appropriate for power terminal wiring, to ensure that voltage drops do not exceed 2%. • Use copper cables rated at 600 V, 75℃ for power terminal wiring. • Use copper cables rated at 300 V, 75℃ for control terminal wiring. • If you need to rewire the terminals due to wiring-related faults, ensure that the inverter keypad display is turned off and the charge lamp under the terminal cover is off before working on Connecting the Cables 57 wiring connections. The inverter may hold a high-voltage electric charge long after the power supply has been turned off. 4.4 Ground Connection Install ground connections for the inverter and the motor by following the correct specifications to ensure safe and accurate operation. Using the inverter and the motor without the specified grounding connections may result in electric shock. • Do not use the ground terminal as the signal (control) ground. • Do not share the ground connection with other machines that consume a large amount of power, such as a welding machine. • Connect the ground cable to the nearest earth contact and keep the cable length as short as possible. Because the inverter is a high-frequency switching device, leakage current may occur during operation. To avoid the danger of electrocution due to current leakage, the inverter must be properly grounded. Ground connection must be made to the specified ground terminal on the inverter. Do not connect ground cables to chassis screws. Note • 200 V products require Class 3 grounding. Resistance to ground must be ≤ 100 Ω. • 400 V products require Special Class 3 grounding. Resistance to ground must be ≤ 10 Ω. The following table lists the minimum ground cable specifications that must be met to properly ground the inverters.

The installation of an external DC reactor is not necessary for these inverters. • The inverter must be properly grounded using the ground terminal. Note If the forward command (Fx) is turned on, the motor should rotate counterclockwise when viewed from the load side of the motor. If the motor rotates in the reverse direction, switch the cables at the U and V terminals. Remarque Si la commande avant (Fx) est activée, le moteur doit tourner dans le sens anti-horaire si on le regarde côté charge du moteur. Si le moteur tourne dans le sens inverse, inverser les câbles aux bornes U et V. Connecting the Cables 61 4.6 Connecting Cables to the Power Terminal Block Power supply cables must be connected to the R, S, and T terminals. Connecting power cables to other terminals will damage the inverter.

Loose screws may cause the terminals to short circuit and malfunction. 2) Only use copper wires with a 600 V, 75℃ rating for the power terminal wiring. 4.7.1 Cable Length between the Inverter and the Motor The maximum cable lengths of the inverter and the motor are listed in

.
Make sure that the total cable length does not exceed 495 ft (150 m). For inverters with a
capacity of less than 3.7 kW, ensure that the total cable length does not exceed 165 ft (50 m).
Long cable runs can cause reduced motor torque in low frequency applications due to voltage
drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may
trigger over-current protection devices, or result in the malfunction of equipment connected to
the inverter.

Inverter capacity Up to 3.7 kW 5.5 kW or more
Maximum cable length < 164 ft (50 m) < 492 ft (150 m) The following table lists maximum carrier frequencies available for model types with a rated capacity of 5.5 kW or more.

Distance < 165 ft (50 m) < 330 ft (100 m) > 330 ft (100 m)
Allowed Carrier Frequency <15 kHz <5 kHz <2.5 kHz Depending on the system layout and operating conditions at the installation site, high peak output voltage may result. Connecting the Cables 68 a) If the output peak voltage is too high even when the motor cable length is sho rter than the maximum recommended cable length for the inverter capacity: - use a motor with a high insulation rating. - install an output circuit filter (micro surge filter). - install a dv/dt filter, or a sine wave filter. b) If the cable length is too long: - use thicker cables to prevent voltage drop. [Voltage Drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current (A)] / 1000] - do not use 3-core cables. - use a lower carrier frequency. 4.7.2 Protective Measures for the Inverter and the Motor The inverter output voltage pulse, regardless of the actual output frequency, is identical to the DC link voltage pulse, which has a very short rising time. When the power is transmitted through the output cables, the output peak voltage can rise up to twice the total DC link voltage (2.8 times the main power voltage). If a switching device (a magnetic contactor or relay) is connected to the output side of the inverter, high-voltage surges may result whenever a switch is made, regardless of the length of the motor cable. Such high-voltage surges can damage the inverter’s output components (such as the current sensor), motor cables, and the motor itself. To protect the inverter and the motor from such damage caused by a high-voltage surge, do not install switching devices in the output side of the inverter. You can install an output reactor, dv/dt filter, or sine wave filter to protect the inverter and motor from a surge voltage. An output surge with a high switching frequency and fast rising time causes a motor shaft current that runs through the motor bearing. It slowly corrodes the surface of the motor bearing, eventually seizing up the motor. To decrease the motor shaft current and protect the motor insulation, refer to
. Install a dv/dt filter or sine wave filter if possible,
regardless of the length of the motor cable.

• Use a potentiometer rated for 0.5 W, 1 kΩ.

If the analog voltage (V) or current (I) input is used to set the frequency reference, the analog
input is reflected when the input is actually received. For instance, the voltage input 0 V at V1
does not indicate that no input is received at V1, but it means that 0 V input is actually received
at V1.
Note
When you use the analog voltage input, the bipolar input range (-10 – +10V), in comparison to the
unipolar input range (0–10V), allows for more accurate input control with smaller increments.

If the analog input is interrupted when setting a frequency reference using the analog voltage (V)
input and no voltage input is received at the terminal, an offset voltage may be applied to keep the
frequency reference at approximately 4–5 Hz.

Connecting the Cables 76 4.12 Setting the Built-in Surge Filter The iS7 series inverters have a built-in surge filter between the input phases and the ground connection to absorb and mitigate surge current. This filter consists of a Y-CAP and multiple varistors. However, in a non-grounded power system where specific ground faults occur frequently, adequate measures are required to avoid inverter damage. Refer to the following table for details on how to prevent damage to specific power systems. Power supply system and ground type Varistors and Y-CAP connection Effect Directly grounded system 2-pin connector (on) Reduced voltage stress and noise Non-grounded or impedance ground system 2-pin connector (off) Reduced risk of inverter damage if ground fault occurs Note The 0.75–22 KW (400 V) and 0.75–75 KW (200 V) products do not support this function. • You can deactivate the built-in surge filter if there is no risk of surge voltage occurring in the system. • In order to prevent accidents, remove the jumper switch after the internal voltage of the inverter is completely discharged. Connecting the Cables 77 4.13 Activating or Deactivating the Surge Filter 4.13.1 iS7 30–75KW (400 V) Inverters Contact LSIS Customer Support and ask for assistance to deactivate the built-in surge filter for the 30–75 KW (400 V) inverters. 4.13.2 iS7 90–375 kW (400V) Inverters Remove the keypad and the screws from the front cover, and then remove the front cover. Be careful not to open the front cover with the keypad attached, as this can damage the keypad cable. Refer to the figure below and locate the SCR snubber board.

4.15.3 Checking the Inverter Operation

Using an inverter, you can easily operate a motor at a high speed. Before operating a motor using
an inverter, ensure that the set speed is within the motor's rated speed.

Follow the instructions to ensure that the motor operates correctly according to the inverter
settings, and adjust the settings if required.
1 Set DRV-06 (CMD source) to “0 (KEYPAD).”
2 Set DRV-07 (Freq Ref Src) to “0 (Keypad-1).”
3 Set DRV-01 (CMD Frequency) to a temporary speed (Ex: 60 Hz).
4 Press the FWD key on the keypad, and ensure that the motor is rotating in the correct
direction. When the forward command (Fx) is on, the motor should rotate
counterclockwise when viewed from the load side of the motor. If the motor rotates in the
reverse direction, switch the cables at the U and V terminals.

Ensure that the input power is within the inverter’s rated input voltage range during operation.

5 Peripheral Devices
The reference diagram below shows a typical system configuration showing the inverter and
peripheral devices.
Prior to installing the inverter, ensure that the product is suitable for the application (power
rating, capacity, etc.). Also, ensure that all of the required peripherals and optional devices
(resistor brakes, contactors, noise filters, etc.) are available.

• Figures in this manual are shown with covers or circuit breakers removed to show a more
detailed view of the installation arrangements. Install covers and circuit breakers before
operating the inverter. Operate the product according to the instructions in this manual.
• Supply input power within the voltage range approved for the inverter's rating.
• Do not start or stop the inverter using a magnetic contactor installed in the input power supply.
• If the inverter is damaged and loses control, the machine may cause a dangerous situation.
Install an additional safety device, such as an emergency brake, to prevent these situations.
• High levels of current draw during power-on can affect the system. Ensure that correctly rated
circuit breakers are installed to operate safely during power-on situations.
• Reactors can be installed to improve the power factor. Note that reactors may be installed
within 32.8 ft (10 m) of the power source if the input power exceeds 1000 kVA.
• 400 V class inverters require a motor with reinforced insulation. Micro surge voltages generated
at the motor terminals may deteriorate the motor insulation.

Note
• If you install the recommended reactors, you can maintain the power factor above 85%, and
keep the THD below 40% for operations at the rated load. Improvements are reduced at lighter
loads.
• Cable impedance affects the input power factor and occurrence of harmonic waves. The input
power factor and THD improvement of the reactors may be lower depending on the
transformer capacity, the transformer impedance, and the cable length.
• Refer to the specifications table and install recommended reactors. Although a higher
inductance value (L) of the reactor results in an improvement in the power factor and better
suppression of harmonic effects, power loss increases at the same time due to voltage drop.
• The capacity of built-in DC reactors in some iS7 inverter models is based on the normal duty
load factor. Therefore, improvements may be reduced during a heavy duty operation.

0–10 V Input Voltage Setting Details
C ode Description

IN-01 Freq at 100%

Configures the frequency reference at the maximum input voltage when a
potentiometer is connected to the control terminal block. A frequency set with
code IN-01 becomes the maximum frequency only if the value set in code IN-
11 (or IN-15) is 100%.
• Set code IN-01 to 40.00 and use default values for codes IN-02–IN-16. The
motor will run at 40.00 Hz when a 10 V input is provided at V1.
• Set code IN-11 to 50.00 and use default values for codes IN-01–IN-16. The
motor will run at 30.00 Hz (50% of the default maximum frequency–60
Hz) when a 10 V input is provided at V1.

IN-05 V1
Monitor[V] Configures the inverter to monitor the input voltage at V1.

IN-07
V1 Filter

The V1 filter may be used when there are large variations between reference
frequencies. Variations can be mitigated by increasing the time constant, but
this requires an increased response time.
The value t (time) indicates the time required for the frequency to reach 63%
of the reference, when external input voltages are provided in multiple steps.

Code Description

IN-17 V1
Quantizing

Quantizing may be used when the noise level is high in the analog input (V1
terminal) signal.
Quantizing is useful when you are operating a noise-sensitive system,
because it suppresses any signal noise. However, quantizing will diminish
system sensitivity (resultant power of the output frequency will decrease
based on the analog input).
You can also turn on the low-pass filter using code IN-07 to reduce the noise,
but increasing the value will reduce responsiveness and may cause pulsations
(ripples) in the output frequency.

Parameter values for quantizing refer to a percentage based on the
maximum input. Therefore, if the value is set to 1% of the maximum analog
input (60 Hz), the output frequency will increase or decrease by 0.6 Hz for
every 0.1 V change in voltage.

When the analog input is increased, an increase in the input equal to 75% of
the set value will change the output frequency, and then the frequency will
increase according to the set value. Likewise, when the analog input
decreases, a decrease in the input equal to 75% of the set value will make an
initial change to the output frequency.

As a result, the output frequency will be different at acceleration and
deceleration, mitigating the effect of analog input changes over the output
frequency (ripples).

Press the [MULTI] key to switch the operation mode to “local.”
“L” (local) is displayed on the keypad, and the command source and frequency
source indication on the keypad (in MON mode) changes to “K/K.”
The inverter stops operating if it was previously running in remote mode, and
you can operate the inverter using the keypad.

Press the [MULTI] key again to switch the operation mode back to “remote.”
“R” (remote) is displayed again on the keypad, and the command source and
frequency source indication on the keypad (in MON mode) changes according
to the previous parameter settings.
The inverter is now ready to operate in remote mode, and the inverter
operation may vary depending on the type of input source.

Note
Local/Remote Operation
• Full control of the inverter is available with the keypad during local operation.
• During local operation, jog commands will only work if one of the multi-function terminals (Px:
P1–P11, codes IN-65–75) is set to “13 (RUN Enable)” and the relevant terminal is turned on.
• During remote operation, the inverter will operate according to the previously set frequency
reference source and the command received from the input device.
• If ADV-10 (power-on run) is set to “0 (No)”, the inverter will not operate on power-on even when
the following terminals are turned on:

- Fwd/Rev run (Fx/Rx) terminal
- Fwd/Rev jog terminal (Fwd jog/Rev Jog)
- Pre-excitation terminal
To operate the inverter manually with the keypad, switch to local mode. Use caution when
switching back to remote operation mode as the inverter will stop operating. If ADV-10 (power-
on run) is set to “0 (No)”, a command through the input terminals will work only after all the
terminals listed above have been turned off and then turned on again.
• If the inverter has been reset to clear a fault trip during an operation, the inverter will switch to
local operation mode at power-on, and full control of the inverter will be with the keypad. The
inverter will stop operating when operation mode is switched from “local” to “remote”. In this
case, a run command through an input terminal will work only after all the input terminals have
been turned off.

Inverter Operation During Local/Remote Switching
Switching operation mode from “remote” to “local” while the inverter is running will cause the
inverter to stop operating. Switching operation mode from “local” to “remote”, however, will cause
the inverter to operate based on the command source:
• Analog commands via terminal input: The inverter will continue to run without interruption
based on the command at the terminal block. If a reverse operation (Rx) signal is ON at the
terminal block at startup, the inverter will operate in the reverse direction even if it was running
in the forward direction in local operation mode before the reset.
• Digital source commands: All command sources, except terminal block command sources
(which are analog sources), are digital command sources that include the keypad, LCD keypad,
and communication sources. The inverter stops operating when switching to remote operation
mode, and then starts operating when the next command is given.

7.7 Forward or Reverse Run Prevention
The rotation direction of motors can be configured to prevent motors from running in a
forward or reverse direction. When reverse direction prevention is configured, pressing the
[REV] key on the keypad will cause the motor to decelerate to 0 Hz and stop.

The Power-on Run feature can be set up to start an inverter operation after powering up based
on the run commands by terminal inputs (if they are configured).

Use caution when operating the inverter with Power-on Run enabled as the motor will begin
rotating when the inverter starts up.

To enable Power-on Run, set DRV-06 (command source) to “1 (Fx/Rx-1)” or “2 (Fx/Rx-2)” and
ADV-10 to “1”. If a run command via a terminal input is on, the inverter starts operating
according to the terminal input settings as soon as it is turned on.

Note
• To prevent a repeat fault trip from occurring when a load, such as a fan, is free-running on a
Power-on Run, set CON-71 (speed search options) bit 4 to “1”. The inverter will perform a speed
search at the beginning of the operation. If the speed search is not enabled, the inverter will
start its operation in a normal V/F pattern and accelerate the motor.
• If the inverter has been turned on without Power-on Run enabled, the terminal block command
must be first turned off, and then turned on again to begin the inverter’s operation.

7.9 Reset and Restart
The reset and restart operations can be set up for inverter operation following a fault trip,
based on the terminal block operation command (if it is configured).

• Use caution when operating the inverter with reset and restart enabled as the motor will begin
rotating when the inverter starts up.
• Stop the frequency reference signal if you do not want the inverter to run again after a
reset.

Set PRT-08 (RST Restart) to “1 (yes)” to allow the inverter to start operating after it is reset if a
fault trip occurs. PRT-10 (Retry Delay) sets the delay time for a restart (the time the inverter will
wait before it restarts).
The number of auto-restarts (PRT-09) refers to the number of times the inverter will try
restarting its operation. If fault trips occur again after a restart, the retry number counts down
each time the inverter restarts until the number becomes “0”. Once the inverter restarts
successfully after the initial fault trip, the inverter does not restart until the next fault trip occurs.
The number of auto-restarts set at PRT-09 that decreased after a restart reverts to the original
setting value if successful operation continues for a certain period of time.

Regardless of the operating frequency, acc/dec time values can be set based on the maximum
frequency. To set acc/dec time values based on the maximum frequency, set BAS-08 (Acc/Dec
reference) to “0 (Max Freq)”.
The acceleration time set at DRV-03 (Acceleration time) refers to the time required for the
inverter to reach the maximum frequency from a stopped state (0 Hz). Likewise, the value set at
DRV-04 (Deceleration time) refers to the time required to return to a stopped state (0 Hz) from
the maximum frequency.

60 Hz). Therefore, the time required to reach 30 Hz is 2.5 seconds (half of 5
seconds).

BAS-09 Time scale

Use the time scale for all time-related values. It is particularly useful when
more accurate acc/dec times are required, due to load characteristics, or
when the maximum time range needs to be extended.
Configuration Description

Note that the range of maximum time values may change automatically when the units are
changed. If for example, the acceleration time is set to 6000 seconds, a time scale change from 1

Set DRV-15 to “1 (Auto)” to enable auto torque boost. While manual torque boost adjusts the
inverter output based on the setting values, regardless of the type of load used during the
operation, auto torque boost enables the inverter to automatically calculate the amount of
output voltage required for the torque boost based on the entered motor parameters.
Because auto torque boost requires motor-related parameters, such as stator resistance,
inductance, and no-load current, auto tuning (BAS-20) has to be performed before the auto
torque boost can be configured. Similarly to manual torque boost, configure auto torque boost
while running a load that requires high starting torque, such as lift-type loads. Refer to 8.9 Auto

7.15 Output Voltage Setting
Output voltage settings are required when a motor’s rated voltage differs from the input
voltage to the inverter. Set BAS-15 to configure the motor’s rated operating voltage. The set
voltage becomes the output voltage of the inverter’s base frequency. When the inverter
operates above the base frequency, and when the motor’s voltage rating is lower than the
input voltage at the inverter, the inverter adjusts the voltage and supplies the motor with the
voltage set at BAS-15 (motor-rated voltage). If the motor’s rated voltage is higher than the input
voltage at the inverter, the inverter will supply the inverter input voltage to the motor.
If BAS-15 (motor-rated voltage) is set to “0,” the inverter corrects the output voltage based on
the input voltage in the stopped condition. If the frequency is higher than the base frequency
andwhen the input voltage is lower than the parameter setting, the input voltage will be the
inverter output voltage.

7.16.2 Start After DC Braking
This start mode supplies a DC voltage for a set amount of time to provide DC braking before an
inverter starts to accelerate a motor. If the motor continues to rotate due to inertia, DC braking
will stop the motor, allowing the motor to accelerate from a stop. DC braking can also be used
with a mechanical brake connected to a motor shaft when a constant torque load is applied, if
a constant torque is required after the mechanical brake is released.

The amount of DC braking required is based on the motor’s rated current. Do not use DC braking
resistance values that can cause current draw to exceed the rated current of the inverter. If the DC
braking resistance is too high or brake time is too long, the motor may overheat or be damaged.

7.17.2 Stop after DC Braking
When the operation frequency reaches the set value during deceleration (DC braking
frequency) the inverter stops the motor by supplying DC power to the motor. With a stop
command input, the inverter begins decelerating the motor. When the frequency reaches the
DC braking frequency set at ADV-17, the inverter supplies DC voltage to the motor and stops it.

Sets the amount of DC braking to apply. The parameter setting is based on the

ADV-17 DC-
Brake Freq

Sets the frequency to start DC braking. When the frequency is reached, the
inverter starts deceleration. If the dwell frequency is set lower than the DC
braking frequency, the dwell operation will not work and DC braking will start
instead.

• The motor can overheat or be damaged if an excessive amount of DC braking is applied to the
motor or if the DC braking time is set to a high value.
• DC braking is configured based on the motor’s rated current. To prevent overheating or
damaging motors, do not set the current value higher than the inverter’s rated current.

When there is high inertia on the output side and the motor is operating at high speed, the load’s
inertia will cause the motor to continue rotating even after the inverter output is blocked.

7.17.4 Power Braking
When the inverter’s DC voltage rises above a specified level due to motor-regenerated energy,
a control is made to either adjust the deceleration gradient level or reaccelerate the motor in
order to reduce the regenerated energy. Power braking can be used when short deceleration
times are needed without brake resistors, or when optimum deceleration is needed without
causing an over voltage fault trip.

ADV 08 Stop mode Stop Mode 4 Power Braking - -

• To prevent overheating or damaging the motor, do not apply power braking to loads that
require frequent deceleration.
• Stall prevention and power braking only operate during deceleration, and power braking takes
priority over stall prevention. In other words, when both bit 3 of PRT-50 (stall prevention and
flux braking) and ADV-08 (braking options) are set, power braking will take precedence.
• Note that if the deceleration time is too short or the inertia of the load is too great, an

C ode Description
ADV-24 Freq Limit

The initial setting is “0 (No).” Changing the setting to “1 (Yes)” allows you to
set the lower limit frequency (ADV-25) and the upper limit frequency (ADV-
26). When the setting is “0 (No)”, codes ADV-25 and ADV-26 are not visible.

ADV-25 Freq Limit Lo
ADV-26 Freq Limit Hi

Sets upper and lower frequency limits. All frequency selections are
restricted to frequencies from within the upper and lower limits.
This restriction also applies when you in input a frequency reference using
the keypad.

ADV-34 Jog Freq Limit

This code allows you to select whether to use the frequency limit function
with frequency upper/lower limits for jog operations.
When ADV-34 is set to “Yes”, the frequency limit is applied if the frequency
limit function using the frequency upper/lower limits is set the same as a
normal operation for jog operations.
When ADV-34 is set to “No”, the frequency limit value is not applied even if
the frequency limit function using the frequency upper/lower limits is set
for jog operations. However, the frequency limit for the maximum
frequency and the start frequency applies.

• When ADV-24 (Freq Limit) is set to “Yes,” the frequency set at ADV-25 (Freq Limit Lo) is the
minimum frequency (Low Freq). If ADV-24 (Freq Limit) is set to “No,” the frequency set at DRV-19
(Start Freq) becomes the minimum frequency.
• When ADV-24 (Freq Limit) is set to “Yes,” the frequency set at ADV-26 (Freq Limit Hi) is the

7.18.3 Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies. The inverter will avoid specific
frequency ranges during acceleration and deceleration. Operation frequencies cannot be set
within the preset frequency jump band.
When the operation frequency is increased while the frequency parameter setting value
(voltage, current, RS-485 communication, keypad setting, etc.) is within a jump frequency band,
the frequency will be maintained at the lower limit value of the frequency band. Then, the
frequency will increase when the frequency parameter setting exceeds the range of
frequencies used by the frequency jump band.

If signals are provided to the multi-function terminal set as the 2nd
command source (2nd Source), the operation can be performed using the
values set at BAS-04–05 instead of the values set at DRV-06 and DRV-07.
The 2nd command source settings cannot be changed while operating with
the 1st command source (Main Source).

BAS-06 Trq 2nd Src

If signals are provided to the multi-function terminal set as the 2nd
command source (2nd Source), the operation can be performed using the
torque reference set at BAS-06 instead of the value set at DRV-08.
Codes DRV-08 and BAS-06 are visible only when DRV-09 (Control mode) is set
to “sensorless” or “vector” control mode, and DRV-10 (Torque control) is set
to “Yes.”

• When you set the multi-function terminal to the 2nd command source (2nd Source) and input
the signal, the inverter’s operation state changes according to the operation frequency and the
operation command configured for the 2nd command. Before shifting the input to the multi-
function terminal, ensure that the 2nd command is correctly set. An overvoltage fault trip may
occur if the deceleration time is too short or the inertia of the load is too high.
• Depending on the parameter settings, the inverter may stop operating when you switch
command modes.

For jog operation 1, an operation command must be entered to start an operation, but while
using jog operation 2, a terminal that is set for a forward or reverse jog also starts an operation.
The priorities for the frequency, acc/dec time and terminal block input during operation in
relation to other operating modes (Dwell, 3-wire, up/down, etc.) are identical to jog operation 1.
If a different operation command is entered during a jog operation, it is ignored and the
operation maintains the jog frequency.

IN-65–75 Px Define

Select two terminals for up/down operation and set them to “19 (Up)” and
“20 (Down)”, respectively. With the operation command input, acceleration
begins when the Up terminal signal is on. Acceleration stops and constant
speed operation begins when the signal is off.

During operation, deceleration begins when the Down signal is on.
Deceleration stops and a constant speed operation begins when both the
Up and Down signals are entered at the same time.

ADV-65 U/D Save
Mode

During a constant speed operation, the operating frequency is saved
automatically under the following conditions: The operation command (Fx
or Rx) is off, a fault trip occurs, or the power is off.

You can also save the up/down operation frequency while the inverter is
operated at a constant speed by setting one of the multi-function terminals
(IN-65–75) to “19 (U/D Save)”, or by setting ADV-65 to “1 (Yes)”.
If the up/down frequency saving function is enabled for the terminal and

8.6 Dwell Operation
When DRV-09 (Control mode) is set to “0 (V/F mode)”, a dwell operation may be used to
maintain torque during inverter application, such as when enough torque is required before
releasing mechanical brakes on lift-type loads. A dwell operation is based on the acc/dec dwell
frequency and the dwell time set by the user. The following conditions also affect dwell
operations.
• Acceleration Dwell Operation: When an operation command is given, acceleration
continues until the acceleration dwell frequency and constant speed is reached within the
acceleration dwell operation time (Acc Dwell Time). After the Acc Dwell Time has passed,
acceleration is carried out based on the set acceleration time and operation speed.
• Deceleration Dwell Operation: When a stop command is given, deceleration continues
until the deceleration dwell frequency and constant speed are reached within the
deceleration dwell operation time (Dec Dwell Freq). After the set time has passed,
deceleration is carried out based on the set deceleration time, and then the operation
stops.

8.7 Slip Compensation Operation
Slip refers to the variation between the setting frequency (synchronous speed) and motor
rotation speed. As the load increases, there can be variations between the setting frequency
and motor rotation speed. Slip compensation is used for loads that require compensation of
these speed variations.*

*If DRV-09 is set to Sensorless, Vector, or V/F PG, the variation (slip) is automatically compensated.

compensates the load by using the previously calculated slip. When
accelerating, the load is compensated by carrying out the sleep
operation regardless of this frequency value. When decelerated, the load
is compensated by using the previous calculated slip regardless of this
frequency.
When this value is set to 0, the slip operation is compensated in real time
at all frequencies regardless of acceleration/deceleration and constant
speed

8.8 PID Control
PI D control is one of the most common auto-control methods. It uses a combination of
proportional, integral, and differential (PID) controls that provide more effective control for
automated systems. The functions of PID control that can be applied to the inverter operation
are as follows:
Purpose Function

Speed Control

Controls the speed by monitoring the current speed levels of the
equipment or machinery being controlled. This control maintains a
consistent speed or operates at the target speed.

Pressure Control

Controls the pressure by monitoring the current pressure levels of
the equipment or machinery being controlled. This control
maintains a consistent pressure or operates at the target pressure.

Flow Control

Controls the flow by monitoring the current amount of flow in the
equipment or machinery being controlled. This control maintains a
consistent flow or operates at a target flow.

Temperature Control

Controls the temperature by monitoring the current temperature
levels of the equipment or machinery being controlled. This control
maintains a consistent temperature or operates at the target
temperature.

8.8.1 PID Basic Operation
PID operates by controlling the output frequency of the inverter, through automated system
process control to maintain the speed, pressure, flow, temperature, or tension.

The setting range of P-gain is 0.0–1000.0%. You can set APP-26 (P-Gain
Scale) to adjust the input scale if a more accurate control is required.

APP-23 PID I-Time

Sets the time to output accumulated errors. When the error is 100%, the
time taken for 100% output is set. When the integral time (PID I-Time) is
set to 1 second, 100% output occurs after 1 second of the error and
remains at 100%. Differences in a normal state can be reduced by PID I
Time. When the multi-function terminal block is set to “21 (I-Term Clear)”

APP-24 PID D-Time

Sets the output volume for the rate of change in errors. If the differential

100%, output occurs at 1% per 10 ms.
APP-25 PID F-Gain Sets the ratio that adds the target to the PID output. Adjusting this value
leads to a faster response.

APP-27 PID Out LPF

Used when the PID controller output changes too quickly or the entire
system is unstable, due to severe oscillation. In general, a lower value
(default value is 0) is used to speed up response time, but in some cases a
higher value increases stability. The higher the value, the more stable the
PID controller output is, but the slower the response time.

APP-28 PID Mode

8.8.3 PID Sleep Mode
If an operation continues at a frequency lower than the PID operation conditions at APP-38
(Sleep Freq) for a set duration at APP-37 (PID Sleep DT), the inverter enters PID sleep mode. In
PID sleep mode, the inverter resumes PID operation when the PID Wakeup level conditions set
at APP-39 (PID WakeUp Lev) are met.
Code Description

APP-37 PID Sleep DT,
APP-38 PID Sleep Freq

Sets the PID sleep frequency and delay time. The inverter stops
operation and enters sleep mode if an operation is maintained at a
frequency lower than the sleep frequency set at APP-38 for the time
set at APP-37.

APP-39 PID WakeUp Lev,
APP-40 PID WakeUp Mod

Sets the reference for PID wakeup at APP-39. If APP-40 is set to “0
(Below Level)”, PID operation is resumed when the feedback volume is
lower than the reference.

If APP-40 is set to “0 (Below level)”, PID operation will resume when the
feedback volume is lower than the reference.
If APP-40 is set to “1 (Above Level)”, PID operation will resume when
the feedback volume is higher than the reference.
If APP-40 is set to “2 (Beyond level)”, PID operation will resume when
the difference between the speed reference and the feedback is larger
than the wakeup reference set at APP-39.

DRV-09 Control Mode

Sets the control mode to “1 (V/F PG)”. This mode adds a speed controller
to a regular V/F mode. The command frequency becomes the speed

Higher P-gain results in a faster response. However, excessively high P-
gain may lead to unstable operation.
Lower I-gain results in a faster response. However, excessively low P-gain
may lead to unstable operation.

CON-47 PG Slip

Sets the maximum slip for the speed controller as a percentage (%) based
on the rated slip set at BAS-12 (Rated Slip).
For example, if CON-47 is set to 90% when the rated slip set at BAS-12 is

the gain values are not properly set.

DRV-10 Torque Control

Selects the speed control and torque control modes. If you set DRV-10
(Torque control) to “1 (Yes)”, the operation switches into torque control
mode. Refer to 8.14 Torque Control on page 245 for details.

• Torque control is not available during low-speed regeneration and
low-speed operation under a light load. Select vector control
mode instead.
• When the inverter is operated in torque control mode, do not
switch between forward and reverse rotations. Overcurrent or Rx
deceleration fault trips may result.
• When the inverter is operated in sensorless vector control mode,
enable accelerating speed search by setting the CON-71 (Speed

*Medium speed: A speed range that is approximately 50% of the base
frequency.

CON-21 ASR-SL P Gain1,
CON-22 ASR-SL I Gain1

Sets the speed controller proportionately and integral gain values for
sensorless-2 vector control.
The P-gain is proportionate to speed deviation. Increasing the P-gain
increases torque output and immediately eliminates speed deviation.
The I-gain is an integral gain which represents the time (ms) until the
torque output is made under a steady speed deviation. Decreasing the
I- gain can eliminate the speed deviation faster.
After setting the speed controller gain values, observe the changes and
fine-tune the values to improve the speed control waveforms. Note that
vibration may result if the set P-gain value is too large or the set I-gain
value is too small. If oscillation is observed in the waveform, first
increase the I-gain, and then increase the P-gain to find the optimal
values.

CON-23 ASR-SL P Gain2,
CON-24 ASR-SL I Gain2

These codes are visible only when CON-20 is set to “1 (yes)”.
Set the speed controller proportionately and integral gain values for
sensorless-2 vector control for operation speeds greater than 50% of
the base frequency.
CON-23 (ASR-SL P Gain2) and CON-24 (ASR-SL I Gain2) are set as
percentage values (%) based on the proportionately set speed controller
and integral gain1 values set at CON-21 (ASR-SL P Gain1) and CON-22
(ASR-SL I Gain1).
Therefore, P-gain2 and I-gain2 values of less than 100% result in
decreased responsiveness when the inverter is operating above
medium speed.* For example, if both P-gain1 and P-gain2 are set to
50%, the actual P-gain2 value is 25% of the reference. Likewise, if I-gain1
is set to 100 ms and I-gain2 is set to 50%, the resulting I-gain 2 value
becomes 200 ms. By default, the speed controller gain values are set
according to the motor parameters and acceleration and deceleration
times.

*Medium speed: A speed range that is approximately 50% of the base
frequency.

CON-26 Observer Gain1,
CON-27 Observer Gain2,
CON-28 Observer Gain3

These codes are visible only when CON-20 is set to “1 (yes)”.
The observer gain values may be adjusted by system engineers only.
Sensorless-2 vector control mode requires the observers to estimate the
motor’s stator current and rotor magnetic flux.
While observer gain1 (CON-26) is applied when the inverter operates at
low to medium speeds, observer gain2 (CON-27) is applied when the
inverter operates at medium to high speeds. Observer gain3 (CON-28) is
applied in torque control mode.

CON-30 S-Est I Gain1

Sets the speed estimator gain values for sensorless-2 vector control

small increments if the displayed speed does not match the speed
reference.
You can also adjust the speed estimator gain values if the motor
vibrates severely, or a high current ripple occurs at power on. Decrease
the speed estimator P-gain or I-gain gradually to reduce the vibration or

By default, the speed estimator gains are set according to the default
motor parameters and acceleration and deceleration times.

CON-32 S-Est I Gain2

These codes are visible only when CON-20 is set to “1 (yes)”.

You can set the speed estimator gains to a frequency higher than the
medium speed* in sensorless-2 vector control mode.
CON-31 and CON-32 are set as percentage values of low-speed gain
values set at CON-29 and CON-30. For example, if CON-29 S-Est P-Gain1
is 300 and CON-31 S-Est P-Gain2 is 40.0%, the speed estimator P-gain at
higher than the actual medium speed is 120.
By default, the speed estimator gains are set according to the default
motor parameters and acceleration and deceleration times.
*Medium speed: A speed range that is approximately 50% of the base
frequency.

CON-34 SL2 OVM Perc

When the output voltage/input voltage ratio is below 100% (when the
output voltage is not over modulated), the output voltage bears linear
characteristics to the input voltage. In sensorless-2 control mode, you
can set CON-34 (SL2 OVM Perc) to define a voltage range to be limited in
the over modulated zone. By default, CON-34 (SL2 OVM Perc) is set as
120%. However, for a high-impact load where the load often exceeds
the torque limit, such as a press load, you can increase the limit value to
avoid frequent over current fault trips.
Also, in areas where the power supply is unstable, the input voltage
tends to be lower than the rated input voltage, which results in more
frequent overcurrent (OC1) fault trips with aforementioned high-impact
load applications. If this is the case, you can set CON-34 (SL2 OVM Perc)
as 140–150% to avoid frequent fault trips.

CON-48 ACR P-Gain,
CON-49 ACR I Gain Sets the current PI controller P-gain and I-gain values.

DRV-10 Torque Control

Selects the speed control and torque control modes. If you set DRV-10
(Torque control) to “1 (Yes)”, the operation switches to torque control
mode.

Code Description
• Torque control is not available during low-speed regeneration and

low-speed operation under a light load. Select vector control mode
instead.
• When the inverter is operated in torque control mode, do not
switch between forward and reverse rotations. Overcurrent or Rx
deceleration fault trips may occur.
• When the inverter is operated in sensorless vector control mode,
enable accelerating speed search by setting the CON-71 (Speed
search) bits to “0001,” if the inverter is expected to start or restart
while the motor is free-running.

In sensorless-2 control mode, the motor may overheat or the system may become unstable if the
gain values are not properly set.
Note
Sensorless-2 vector control mode is greatly affected by the motor and load characteristics.
Therefore, it is sometimes necessary to adjust the controller gain values.
When a sensorless-2 vector control is operated in speed mode [DRV-10 (torque control) is set to “0
(No)”. If the operation is unstable at extremely low speeds (below 2–3 Hz), or if the speed bounces
during startup, increase the CON-22 (ASR-SL I Gain1) value to 200% of the default value. With a
regenerative load, motor torque ripples may occur frequently. In this case, decrease the CON-21
(ASR-SL P Gain1) value to 50% of the default value. If this does not solve the problem, increase the
CON-21 (ASR-SL P Gain1) value back to the default, and decrease the CON-30 (S-Est I Gain1) value to
50% of the default value.

8.13 Vector Control Mode Operation
With an optional encoder module installed to the inverter, vector control mode provides highly
precise operation abilities.
Similar to sensorless-1 and sensorless-2 vector control modes, vector control mode requires
motor parameter values for operation. Before operating the inverter in sensorless-2 mode, run
auto tuning first.

8.14 Torque Control
You can use torque control to operate the inverter to produce a certain amount of torque as
indicated by the torque reference. In torque control mode, the motor speed is decided by the
amount of load because a motor can run at a constant speed when the output torque and
torque load are equal. The motor speed increases when the output torque becomes greater
than the torque load. You can set a speed limit to maintain the motor speed within a certain
range. Note that torque control is not available during the speed control operations.

motor and the direction of the operation command

produce a satisfactory result because the direction of

1 Flying Start-2

The speed search is carried out by the PI controller,
which controls the ripple current generated by the
counter electromotive force during no-load rotation.
As this mode establishes the direction of the idling
motor (forward/reverse), the speed search function
is stable regardless of the direction of the idling
motor and direction of the operation command.
However, because the ripple current is used, which is
generated by the counter electromotive force while
idling (the counter electromotive force is
proportional to the idle speed), the idle frequency is
not determined accurately and re-acceleration may
start from zero speed when the speed search is
performed for the idling motor at a low speed (about
10 - 15 Hz, though it depends on motor
characteristics).

operation. When the motor is rotating under load, a fault trip may occur if
the operation command is run for the inverter to provide voltage output.
The speed search function prevents such fault trips from occurring.
Initialization after a fault trip other than an LV trip: If bit 2 is set to “1”
and PRT-08 (RST Restart) is set to “1 (Yes)”, the speed search operation
automatically accelerates the motor to the operation frequency used before
the fault trip when the [STOP/RESET] key is pressed (or the terminal block
input is on) after a fault trip.
Automatic restart after an instantaneous power interruption: If bit 3 is
set to “1”, and if a low voltage trip occurs due to a power interruption but
the power is restored before the internal power shuts down, the speed
search operation accelerates the motor back to its frequency reference
before the low voltage trip.

If an instantaneous power interruption occurs and the input power is
disconnected, the inverter generates a low voltage trip and blocks the
output. When the input power returns, the operation frequency before the
low voltage trip and the voltage is increased by the inverter’s inner PI
controller.

If the current increases above the value set at CON-72, the voltage stops
increasing and the frequency decreases (t1 zone). If the current decreases
below the value set at CON-72, the voltage increases again and the
frequency stops decelerating (t2 zone). When the normal frequency and
voltage are resumed, the speed search operation accelerates the motor
back to its frequency reference before the fault trip.

CON-72 SS Sup-
Current

The amount of current flow is controlled during speed search operation
based on the motor’s rated current. If CON-70 (SS mode) is set to “1 (Flying
Start-2)”, this code is not visible.

CON-73 SS P-Gain,
CON-74 SS I-Gain

The P/I gain of the speed search controller can be adjusted. If CON-70 (SS
Mode) is set to “1”(Flying Start-2), different factory defaults based on motor
capacity [at DRV-14 (Motor Capacity)] are used.

CON-75 SS Block
Time

The block time parameter prevents overvoltage trips due to counter
electromotive force by cutting off the inverter output for the set time before
carrying out a speed search.

Note
• If operated within the rated output, the iS7 series inverter is designed to withstand
instantaneous power interruptions of up to 15 ms and maintain normal operation [when 200–
230 V AC input voltage is supplied to 200 V class model types, and 380–460 V AC input voltage is
supplied to 400 V class model types, and when the inverter is operating with static load current
(CT load)].
• The DC voltage inside the inverter changes depending on the load. Low voltage fault trips may
result if the power interruption lasts longer than 15 ms, or the output voltage exceeds the rated
input voltage.

8.20 Auto Restart Settings
When inverter operation stops due to a fault and a fault trip is activated, the inverter
automatically restarts based on the parameter settings.

PRT-09
Retry Number,
PRT-10
Retry Delay

The number of available auto restarts can be set at PRT-09. If a fault trip
occurs during an operation, the inverter restarts after the time set at PRT-10
(Retry Delay). At each restart, the inverter counts the number of tries and
subtracts it from the number set at PRT-09 until the retry number count
reaches 0. After an auto restart, if a fault trip does not occur within 60 sec, it
will increase the restart count number. The maximum count number is
limited by the number set at PRT-09.

If the inverter stops due to low voltage, an emergency stop, an inverter
overheating, or a hardware malfunction, auto restart is not activated.

At auto restart, the acceleration options are identical to those of the speed
search operation. Codes CON-72–75 can be set based on the load. For the
speed search function details, refer to 8.19 Speed Search Operation on page
254.

CON-05 PWM
Mode

The heat loss and leakage current from the inverter can be reduced by
changing the load rate option at CON-05 (PWM Mode). Selecting “1
(LowLeakage PWM)” reduces heat loss and leakage current, compared to
when “0 (Normal PWM)” is selected. However, it increases the motor noise.
Low leakage PWM uses a two-phase PWM modulation mode, which helps
minimize degradation and reduces switching loss by approximately 30%.

• The factory default carrier frequency for 90–160 kW model types is 3 kHz. The figure in the
red box (D: 5.0) is a factory default carrier frequency for models types up to 75 kW,
provided for your reference only.

• Since low carrier frequencies can transmit a much higher frequency than the capacity of
the output current, an increase in motor loss will occur. Some motors may stall due to
increased high frequency current and lack of torque may cause the inverter to stop.

Brake Operation Sequence in Control Modes Other than
“Vector”


During the motor stop state, if an operation command is entered,
the inverter accelerates up to the brake release frequency (ADV-44–
45) in a forward or reverse direction.
After reaching the brake release frequency, if the motor current
reaches the brake release current (BR Rls Curr), the output relay or
multi-function output terminal for brake control sends a release
signal.
Once the signal has been sent, acceleration will begin after
maintaining the frequency for the brake release delay time (ADV-42
BR Rls Dly).


If a stop command is sent during operation, the motor decelerates.
Once the output frequency reaches the brake engage frequency (ADV-
47 BR Eng Fr), the motor stops decelerating and sends out a brake
engage signal to a preset output terminal.
The frequency is maintained for the brake engage delay time (ADV-47
BR Eng Dly) and it becomes “0” afterwards. If the DC braking time (ADV-
15) and DC braking resistance (ADV-16) are set, the inverter output is
blocked after DC braking. For more details on DC braking, refer to
7.17.2 Stop after DC Braking on page 187.

Code Description
Brake Operation Sequence in “Vector” control Mode


When an operational command is entered, the output relay or
multi-function output terminal for brake control sends a brake
release signal after the pre-excitation time is passed. Once the
signal has been sent, acceleration will begin after the brake release
delay time (ADV-42 BR Rls Dly) has passed.


If a stop command is sent during operation, the inverter
decelerates to “0 Hz” and sends out a brake engage signal. Then,
the output is cut off after the brake engage delay time (ADV-46 BR
Eng Dly) has passed.
The brake engage sequence does not operate in torque control
mode.

APP-01 APP Mode

If “3 (MMC)” is selected for the applied function, the items related to
the MMC function are displayed in the option module function
group (APO) and the functions related to the PID controller are
displayed in APP.

APO-20, 21, 33

If the number of auxiliary motors is set at APO-33 and there is more
than one auxiliary motor, the auxiliary motor number for the first
operation should be APO-21. For example, if there are three
auxiliary motors and each of them is controlled by Relay 1 and 2
and the Q1 terminal, the auxiliary motors operate in the sequence
of Relay 2, Q1, and then Relay 1 when”2” is input at APO-21. The
auxiliary motors stop in the sequence of Relay 1, Q1, and Relay 2. At
APO-20, the number of currently operating auxiliary motors can be
monitored.

APO-23–26 Start Freq 1–
4

Sets the starting frequency for auxiliary motors. Since the main
motor is operated by the PID controller, its operating frequency is
increased by the load change and the operation for an auxiliary
motor becomes necessary. The conditions of the inverter output
terminal I (Relay or multi-function output [Qx]) that turns on for
auxiliary motor operation is as follows. The auxiliary motor can
operate when
• The speed of the main motor exceeds the starting frequency (APO-
23–26) of the auxiliary motor.
• The starting delay time (APO-13) of the auxiliary motor passes.
• The difference between the reference and the feedback of the
main motor PID controller becomes smaller than the pressure
difference (APO-40) of the auxiliary motor motion.

APO-27–30 Stop Freq 1–4

Sets the stop frequency for auxiliary motors. If the operating
frequency for the main motor decreases below a certain frequency
while the auxiliary motor is running, the auxiliary motor should be
stopped. The condition of the auxiliary motor to be stopped is as
follows. The auxiliary motor can be stopped when
• The speed of the main motor decreases below the stop frequency
(APO-27–30) for the auxiliary motor.
• The stop delay time (APO-32) for the auxiliary motor passes.
• The difference between the reference and the feedback of the
main motor PID controller becomes larger than the pressure

stops. When the auxiliary motor runs, the main motor decelerates
to the decelerating frequency of the auxiliary motor for the
decelerating time set at APO-42. Inversely, when the auxiliary
motor stops, the main motor accelerates to the starting frequency
for the accelerating time set at APO-41.

8.39.2 Auto Change Operation
The auto change function enables the inverter to automatically switch operations between
main and auxiliary motors. Prolonged continuous operation of a motor reduces motor
performance. The auto change function switches the motors automatically when certain
conditions are met to avoid biased use of certain motors and protect them from deterioration.
Code Description

APO-35 Auto
Ch Mode

Selects the motors to apply the auto change function.

0: None
The operation sequence of the auxiliary motor starts with the auxiliary motor
selected at APO-21(starting auxiliary motor selection) and the automatic
change function is not active.

1: Aux
The operation sequence of the auxiliary motor starts with the auxiliary motor
selected in APO-21(starting auxiliary motor selection). When the cumulative
operating time for a main and auxiliary motor exceeds the auto change time
(APO-36), the auto change condition is met. If the main motor is stopped by a
stop command or the sleep operation mode after the auto change condition,
the start sequence of the auxiliary motor selected at APO-21 is changed.
For example, if there are four auxiliary motors operating and motor 4 is
selected in APO-21, the start sequence of the auxiliary motor automatically
changes to motor 1. Therefore, the previous start sequence of the auxiliary
motor of 4, 1, 2, and 3 changes to 1, 2, 3, and 4, and if the auto change
condition is met, the sequence is changed to 2, 3, 4, and 1.

Learning Advanced Features

Advanced
Features

291

Code Description

2: Main
Auto change is available without distinction between the main and auxiliary
motors. The auto change condition is met if the cumulative operating time for
the motor connected to the inverter output exceeds the auto change time
(APO-36).

If the inverter is stopped by a stop command or sleep operation mode, the
operating sequence of the motor automatically changes. For example, if the
starting auxiliary motor selection (APO-21) is set at “2”, the inverter output is
connected to motor 2. If there are four motors and the auxiliary motor
operating condition is met, motors 3, 4, and 1 start operating one after
another in sequence. If the inverter stops in the auto change condition, motor
3 is connected to the inverter output in the next restart and the auxiliary
motors operate in the sequence of 4, 1, and 2.

8.39.3 Interlock Operation
When there is motor trouble, the interlock feature is used to stop the affected motor and
replace it with another that is not currently operating (i.e. in the off state). To activate the
interlock feature, connect the cables to send abnormal motor signals to the inverter input
terminal and configure the terminals as interlock 1–4 inputs. Then, the inverter decides the
motor’s availability based on the signal inputs. The order in which the alternative motor is
selected is decided based on the auto change mode selection options set at APO-35.
Code Description

IN-65–75 Px Define

The terminal to use as the interlock among IN 65–72 (up to 75 if
there is an I/O expansion module) is selected and Interlock 1–4 are

(Aux)” and if auxiliary motors 1, 2, and 3 are connected to inverter
output terminals Relay 1, 2, and Q1 when a total of four motors
including the main motor is operating, the interlock numbers 1, 2,
and 3 correspond to the motor connected to Relay 1, 2, and Q1.

Learning Advanced Features

293

Code Description
However, if the auto change mode selection (APO-35) is set to “2
(Main)” and the main and auxiliary motors are connected to
inverter output terminals Relay1, 2, Q1, and Q2 (I/O expansion
module used) respectively, Interlock 1, 2, 3 and 4 correspond to the
motors connected to Relay 1, 2, Q1 and Q2.

APO-38 Interlock

Select “1 (Yes)” to enable an interlock operation.

1) If there are five motors and the auto change mode selection
(APO-35) is set to” 0 (None)” or “1 (Aux)”, the operation is as follows:

If signals are sent to the terminal block set at Interlock 3 with a fault
at motor 3 when it is static, the auxiliary motors operate in the
sequence of 1, 2, and 4 (when the starting auxiliary motor selection
APO-21 is “1”). If the terminal block signals are released, the
operation sequence is 1, 2, 3, and 4.

If signals are sent to the terminal for Interlock 3, auxiliary motor 3
stops and auxiliary motor 4 operates. If the interlock signal is
released, auxiliary motor 4 stops and auxiliary motor 3 operates
again.

2) If there are four motors and the auto change mode selection
(APO-35) is set to “2 (Main)”, the operation is as follows:

If the starting auxiliary motor selection APO-21 is set to “1”, motor 1
is operated by the inverter and the remaining motors (2, 3, and 4)
are operated by the auxiliary motors and interlock signals are sent
to the auxiliary motors, the operation sequence is the same as the
procedure described in condition 1) above.

However, if there is a problem with motor 1, which is connected to
the inverter, the output is immediately blocked and motor 2
becomes connected to the inverter output and the operation
sequence of the auxiliary motor is 3 and 4. If the interlock signal of
motor 1 is released, the operation sequence of the auxiliary motor
is 3, 4, and 1.

81–83) are displayed. In the above settings, if “51 (Fire Mode)” in IN-65–75
is on, fire mode operates. The basic operation is the same as fire mode.
However, ADV-83 is not counted in fire test mode. Also, all fault trips
occur without ignoring them.
If a fault occurs during fire mode operation, the fault trip is ignored and the inverter
continuously operates. However, if a critical fault occurs, the inverter performs the trip
operation or auto restart operation. The auto restart is performed after PRT-10 Retry Delay is
set.
If the inverter performs the fire mode operation when the inverter is in normal status after the
auto restart, the inverter will operate via the speed search.
Fire mode cannot be set while in torque mode. Therefore, fire mode can only be set when the
inverter is in speed or operation mode.
In fire mode, the operation for fault trips is listed in the following table.

Fire mode operation voids the product warranty. To test fire mode not to increase the fire mode
operation count at ADV-83, set ADV-80 to “2-Fire Test” and operate the inverter.

If the multi-function terminal input set to “51 (Fire Mode)” is on when ADV-83 is set to “1 (Fire
Mode)”, the count value set at ADV-83 is increased by 1.

8.43 Dynamic Braking (DB) Resistor Operation
Reference Voltage
Depending on the capacity, the iS7 series is divided into models with a braking resistor circuit
integrated inside the inverter, and models that require an external braking unit to be installed.
The inverters rated between 0.75–22 kW have the built-in braking model (except for the brake
resistor), and the inverters rated above 30 kW require an external braking unit. Therefore, the
reference voltage setting function for the braking resistor is necessary for inverters rated
below 22 kW.

780 V 400 V Type: 600–800 V
ADV-79 DB Turn On Lev: This is the operation reference voltage for the braking resistor. The
braking resistor operates when the DC link voltage exceeds the reference value.
The initial value for 200 V-type inverters is 390 V, and the initial value for 400 V-type inverters is
780 V.
For 200 V-type inverters, the reference voltage that stops the braking resistor is 10 V lower than
the operating voltage set at ADV-79. For 400 V-type inverters, the braking resistor stops if the

300

voltage is 20 V lower than the operating voltage set at ADV-79.

If the set value for ADV-79 is lower than the DC link voltage when the inverter is in normal
operation, the DB resistor may overheat due to continuous DB resistor operation.
Conversely, if the set value at ADV-79 is much higher than the DC link voltage range, an overvoltage
trip may occur because the DB resistor does not operate when it is needed.

Example) If the input voltage is 440 V and the value at ADV-79 is set to 600 V, the DB resistor
operates when the inverter is on because the DC link voltage is 622 V. Since the voltage level that
stops the DB resistor is 590 V, the DB resistor may overheat due to continuous DB resistor
operation.

When the input current to the motor is greater than the overload warning
level (OL Warn Level) and continues at that level during the overload
warning time (OL Warn Time), the multi-function output (Relay 1, Q1) sends
a warning signal. When Over Load is selected at OUT-31 and OUT-33, the
multi-function output terminal or relay outputs a signal. The signal output
does not block the inverter output.

Setting Function
0 None No protective action is taken.

3 Dec If a fault trip occurs, the motor decelerates and stops.

PRT-21 OL Trip
Level,
PRT-22 OL Trip Time

When the current supplied to the motor is greater than the preset value of
the overload trip level (OL Trip Level) and continues to be supplied during
the overload trip time (OL Trip Time), the inverter output is either blocked
according to the preset mode from PRT-17 or slows to a stop after
deceleration.

Note
Overload warnings warn of an overload before an overload fault trip occurs. The overload warning
signal may not work in an overload fault trip situation, if the overload warning level (OL Warn Level)
and the overload warning time (OL Warn Time) are set higher than the overload trip level (OL Trip
Level) and the overload trip time (OL Trip Time).

10.1.3 Stall Prevention and Flux Braking
The stall prevention function is a protective function that prevents motors from stalling due to
overloads. If a motor stall occurs due to an overload, the inverter operation frequency is
adjusted automatically. When a stall is caused by overload, high currents induced in the motor
may cause motor overheating or damage the motor and interrupt operation of the motor-
driven devices.
In this case, the motor decelerates with optimum deceleration without a braking resistor by
using flux braking. If the deceleration time is too short, an over voltage fault trip may occur
because of regenerative energy from the motor. The flux braking makes the motor use
regenerate energy, therefore optimum deceleration is available without over voltage fault trip.

Code Description
0001 Stall protection
during
acceleration

If the inverter output current exceeds the preset stall
level (PRT-52, 54, 56, 58) during acceleration, the
motor stops accelerating and starts decelerating. If
current level stays above the stall level, the motor
decelerates to the start frequency (DRV-19). If the
current level causes deceleration below the preset
level while operating the stall protection function,
the motor resumes acceleration.

0010 Stall protection
while operating at
constant speed

Similar to stall protection function during
acceleration, the output frequency automatically
decelerates when the current level exceeds the
preset stall level while operating at constant speed.
When the load current decelerates below the preset
level, it resumes acceleration.

0100 Stall protection
during
deceleration

The inverter decelerates and keeps the DC link
voltage below a certain level to prevent an over
voltage fault trip during deceleration. As a result,
deceleration times can be longer than the set time
depending on the load.

1000 Flux braking
during
deceleration

When using flux braking, deceleration time may be
reduced because regenerative energy is expended
at the motor.

1100 Stall protection
and flux braking
during
deceleration

Stall protection and flux braking operate together
during deceleration to achieve the shortest and most
stable deceleration performance.

Level 4

Additional stall protection levels can be configured for different frequencies, based
on the load type. As shown in the graph below, the stall level can be set above the
base frequency. The lower and upper limits are set using numbers that correspond
in ascending order. For example, the range for Stall Frequency 2 (Stall Freq 2)
becomes the lower limit for Stall Frequency 1 (Stall Freq 1) and the upper limit for
Stall Frequency 3 (Stall Freq 3).

Using Protection Features

333

Note
Stall protection and flux braking operate together only during deceleration. Turn on the third and
fourth bits of PRT-50 (Stall Prevention) to achieve the shortest and most stable deceleration
performance without triggering an over voltage fault trip for loads with high inertia and short
deceleration times. Do not use this function when frequent deceleration of the load is required, as
the motor can overheat and be easily damaged.

• Use caution when decelerating while using stall protection since the deceleration time can take
longer than the time set, depending on the load. Acceleration stops when stall protection
operates during acceleration. This may make the actual acceleration time longer than the
preset acceleration time.
• When the motor is operating, Stall Level 1 applies and determines the operation of stall
protection.

PRT-06 IPO V Band

Sets the band of the allowed ripple voltage. If one or more phases from the
inverter output are open, the ripple of the DC link voltage increases. If ripple
voltage exceeds the set ripple voltage band, an input phase open trip occurs.
The IPO V Band may be adjusted depending on the operating environment.

Sets the IPO V Band 1–10 volts higher if the output load is too large for the
input capacity, and an open phase fault trip occurs during a normal
operation.
Sets the IPO V Band 1–10 volts lower if the output load is too smaller for the

standard values.

PRT-14 Lost Preset F

In situations where speed commands are lost, set the operation mode
(PRT-12 Lost Cmd Mode) to “5 (Lost Preset)”. This operates the protection
function and sets the frequency so that the operation can continue.
Set IN-06 (V1 Polarity) to “Unipolar” and IN-08 to “5 (V)”. Set PRT-15 (AI Lost Level) to “1 (Below

10.2.6 Dynamic Braking (DB) Resistor Configuration
The iS7 series is divided into a model which features a built-in braking circuit and the other in
which a separate external braking unit should be installed. 0.75–22 kW model types belong to
the former (braking resistor unit is excluded) and for those model types above 30 kW, you
should install a braking unit on the exterior of the inverter. Therefore the function of limiting
the braking resistance use rate (%ED) is necessary for only models below 22 kW.

Warn %ED

Sets braking resistor configuration (%ED: Duty cycle). Braking resistor
configuration sets the rate at which the braking resistor operates for one
operation cycle. The maximum time for continuous braking is 15 sec and the
braking resistor signal is not output from the inverter after the 15 sec period
has expired. An example of braking resistor set up is as follows:

%?? = ?_???

?_??? + ?_?????? + ?_??? + ?_???? × 100%

[Example 1]

%?? = ?_???

?_??? + ?_??????1 + ?_??? + ?_??????2 × 100%

• T_steady: Constant speed operation time at set frequency
• T_dec: Deceleration time to a frequency lower than constant speed
operation or the stop time from constant speed operation frequency
• T_stop: Stop time until operation resumes

Do not set the braking resistor to exceed the resistor’s power rating. If overloaded, it can overheat
and cause a fire. When using a resistor with a heat sensor, the sensor output can be used as an
external trip signal for the inverter’s multi-function input.

11.1 Introduction
This chapter explains the standards, installation process, and programs for the SV-iS7 inverter
serial communication method when using personal computers or factory automation (FA)
computers. The communication function for the SV-iS7 inverter series is designed to remotely
operate or monitor the SV-iS7 inverter series using personal computers or FA computers.
Advantages of Operating the Inverter with Network Communication
As the inverter can be operated or monitored by the user programs, it is easy to apply the
inverter to factory automation.

RS-485 standard

• Performs communication between the inverter and computers produced
by numerous companies.
• Controls up to 16 inverters at a time with one computer using the multi-
drop link system.
• Provides an interface for noise immunity environments.

Inverters can communicate with computers embedded with the RS-232 module via RS-232/485
converters. The standards and performance of converters may vary depending on the
manufacturer, but the basic functions are the same. For more details about standards and
guidelines, users are advised to consult the manual provided by the specific manufacturer.

Read this manual carefully before installation and operation. All instructions in this manual must be
followed to avoid injury or prevent damage to other components.

11.3 Communication System Configuration
In an RS-485 communication system, the PLC or computer is the master device and the inverter
is the slave device. When using a computer as the master, the RS-232 converter must be
integrated with the computer, so that it can communicate with the inverter through the RS-
232/RS-485 converter. Specifications and performance of converters may vary depending on
the manufacturer, but the basic functions are identical. Please refer to the converter
manufacturer’s user manual for details about features and specifications.
Connect the wires and configure the communication parameters on the inverter by referring to
the following illustration of the communication system configuration.

• RS-485 terminal connection: Connect the RS-485 communication line to the S+/S-/SG
terminals.
• Number of connectable inverters: Up to 16 inverters
• Number of extendable addresses (St ID): 1–250 addresses
• Length of effective communication lines: 1,200 m max. Keep it below 700 m for stable
communication.

When wiring the communication line, make sure that the SG terminals on the PLC and inverter are
connected. SG terminals prevent communication errors due to electronic noise interference.

Use a communication repeater to enhance the communication speed if you have to use a
communication cable above 1,200 m, or to connect an additional inverter. A repeater is
effective when smooth communication is not available due to noise interference.

command addresses with Int485, the Fx function is performed if 0h0001 is input in 0h0385
after COM-70 (Virtual DI 1) is set to “FX”. Before you configure the virtual multi-function inputs,
set the DRV-06 (CMD source) depending on the command source.
Virtual multi-function operates independently from the analog multi-function inputs and
cannot be set redundantly. Virtual multi-function input can be monitored using COM-86 (Virt Dl
Status).

11.8 Saving Parameters Defined by Communication
If you turn off the inverter after setting the common area parameters or keypad parameters
via communication and operate the inverter, the changes are lost and the values changed via
communication revert to the previous setting values when you turn on the inverter.
Set CNF-48 to “1 (Yes)” to allow all the changes over communication to be saved, so that the
inverter retains all the existing values even after the power has been turned off.
Setting address 0h03E0 to “0” and then setting it again to “1” via communication allows the
existing parameter settings to be saved. However, setting address 0h03E0 to “1” and then
setting it to “0” does not carry out the same function.

11.11 Parameter Group for Periodical Data
Transmission
By defining a parameter group for data transmission, the communication addresses registered
in the communication function group (CM) can be used in communication. Parameter groups
for data transmission may be defined to simultaneously transmit multiple parameters into the
communication frame.

When registering control parameters, register the operation speed (0h0005, 0h0380, 0h0381) and
operation command (0h0006, 0h0382) parameters at the end of a parameter control frame. For
example, when the parameter control frame has 5 parameter control items (Para Control - x),
register the operation speed at Para Control-4 and the operation command to Para Control-5.

11.13 Communication Protocol
11.13.1 LS INV 485 Protocol
The slave device (inverter) responds to read and write requests from the master device (PLC or
PC).

1 byte 2 bytes 1 byte 2 bytes 2 bytes 1 byte
• A request starts with ENQ and ends with EOT.
• A normal response starts with ACK and ends with EOT.
• An error response starts with NAK and ends with EOT.
• A station ID indicates the inverter number and is displayed as a two-byte ASCII-HEX string
that uses characters 0-9 and A-F.
• CMD: Uses uppercase characters (returns an IF error if lowercase characters are
encountered).

Character ASCII-HEX Command
‘R’ 52h Read
‘W’ 57h Write
‘X’ 58h Request monitor registration
‘Y’ 59h Perform monitor registration
• Data: ASCII-HEX (for example, when the data value is 3000: 3000 → ‘0’’B’’B’’8’h → 30h 42h
42h 38h)
• Error code: ASCII-HEX (20h–7Fh)
• Transmission/reception buffer size: Transmission=39 bytes, Reception=44 bytes
• Monitor registration buffer: 8 Words
• SUM: Checks communication errors via sum.
• SUM=a total of the lower 8 bits values for station ID, command and data (Station
ID+CMD+Data) in ASCII-HEX.
• For example, a command to read 1 address from address 3000:
SUM=‘0’+‘1’+’R’+‘3’+‘0’+‘0’+‘0’+’1’ = 30h+31h+52h+33h+30h+30h+30h+31h = 1A7h (the control
value is not included: ENQ, ACK, NAK, etc.

Note
Broadcasting
Broadcasting sends commands to all inverters connected to the network simultaneously. When
commands are sent from station ID 255, each inverter acts on the command regardless of the
station ID. However no response is issued for commands transmitted by broadcasting.

Error operation
For two or more data communications, when an error occurs as a result of the previous data
communication, the current data communication can be made normally regardless of the error
occurred as a result of the previous data communication.

Note 1
- Set parameters very carefully. After setting a parameter to “0 “ via communication, set it to another
value. If a parameter has been set to a value other than 0 and a non-zero value is entered again, an
error message is returned. The previously set value can be identified by reading the parameter
when operating the inverter via communication.
Note that the execution time may take longer because the data is saved in the inverter, possibly
interrupting communication.

Note 2
- The addresses 0h03E7 and 0h03E8 are parameters for entering the password. When the
password is entered, the condition will change from “Lock” to “Unlock”, and vice versa.
When the same parameter value is entered repeatedly, the parameter setting is executed just once.
To enter the same value, change it to another value first and then re-enter the previous value. For
example, if you want to enter 244 twice, enter it in the following order: 244 -> 0 -> 244.

14 Safety Funtion STO(Safe Torque Off)
The iS7 Inverter series provides resilient safety features via optional safety expansion module.
When an emergency arises, it instantly blocks inverter output to protect the operator and
reduce the risk.

14.1 Safety Standard Product
The performance levels for the safety function are as follows.
EN ISO 13849-1: Category 3, PL Class d
EN 61508: SIL 2 (EN 60204-1, Stop Category 0)

When using the safety function, perform a risk assessment for the system and ensure that it meets
the safety requirements.

Note
When wiring the inverter or performing maintenance, the inverter must be turned off. The safety
function is not used to block the power supply to the motor or insulate the inverter electrically.

14.2 About the Safety Function
The safety function is a safety torque off (STO) function used to prevent a torque and to block
the power supply to the motor by interrupting the gate using hard wires.
STO (Safety Torque Off): IEC61800-5-2
The STO function is independently connected to each input signal for 2 channels (SE(SFT11) and
SP(SFT2)). The connected circuit cuts off the operation signal for the inverter output and turns
off the power modules.
If the safety function is activated during operation, the inverter blocks the output and the
motor enters Free Run mode. Also, the “Safety Opt Err” message is displayed on the keypad.
To release the fault trip, short-circuit terminal block to return to the normal operation status
and press the [STOP/RESET] key.

Using a Single Phase Power Source

16 Using a Single Phase Power Source

16.1 Single Phase Rating
The SV-iS7 series inverter is a three-phase variable frequency drive (VFD). When applying single-
phase power to a three-phase VFD, there are several limitations that need to be considered.
The standard pulse-width-modulated (PWM) VFDs use a 6-pulse diode rectifier. The 6-pulse
rectification results in 360 Hz DC bus ripple when using a three-phase 60 Hz power supply.
However, when using a single-phase power source, the DC bus ripple becomes 120 Hz. The
input current and harmonics increase, and the VFDs DC bus circuit is subject to higher stress in
order to deliver equivalent power.
Input current distortion of 90% THD and greater can be expected under single-phase input,
compared to approximately 40% with three-phase input as indicated in Figure 2.
Therefore, use of a single-phase requires the three-phase VFD power rating to be reduced
(derated) to avoid over stressing the rectifier and the DC link components.

Using a Single Phase Power Source

453

Single
Phase

16.2 Power(HP), Input Current and Output Current
When using a three-phase VFD with single-phase input, derating the drive’s output current and
horsepower will be necessary due to the increase in DC bus ripple voltage and current. In
addition, the input current through the remaining two phases on the diode bridge converter
will approximately double, creating another derating consideration for the VFD. Input current
harmonic distortion will increase, making the overall input power factor low.
Input current distortion over 100% is likely under single-phase conditions without a reactor.
Therefore, the reactor is always required for such applications.
Using a motor that is selected by the three-phase drive ratings with single-phase input may
result in poor performance and premature drive failure.
The selected drive of single-phase current ratings must meet or exceed the motor current
ratings as indicated in the following table.

* The drive ratings in table are valid for 60 Hz input only.

16.3 Input Frequency and Voltage Tolerance
The AC supply voltage must be within the required voltage range of 240/480 VAC +10% to –5%
to maximize motor power production.
The standard product with three-phase voltage input has an allowable range of +10% to –15%.
A stricter input voltage tolerance of +10 to –5% applies when using the drive with a single-
phase supply. The average bus voltage with single-phase input is lower than the equivalent of a
three-phase input. Therefore, the maximum output voltage (motor voltage) will be lower with a
single-phase input.
The minimum input voltage must be no less than 228 VAC for 240 volt models and 456 VAC for
480 V models, to ensure motor voltage production of 207 VAC and 415 VAC, respectively.
If full motor torque must be developed near the base speed (full power) it will be necessary to
maintain a rigid incoming line voltage so that adequate motor voltage can be produced.
Operating a motor at reduced speed (reduced power), or using a motor with a base voltage
that is lower than the incoming AC supply rating (ex. 208 VAC motor with a 240 VAC supply) will
also minimize the effect of voltage deprivation ( 240 VAC Input for 208 V motor, 480 VAC Input
for 400 V motor).

16.4 Wiring and Peripheral Device
It is important that input wiring and branch circuit protection be selected based on the drive’s
single-phase input current rating indicated in Table 1–2.
The single-phase input current after derating differs from the three-phase input indicated on
the VFD nameplate.
Refer to the following figure and connect the single-phase AC input wiring to the inverter’s R[L1]
and T[L3] terminals.

The drive ratings in Table 1 are valid for 60 Hz input only.

Using a Single Phase Power Source

16.5 Other Considerations
The following lists other precautions that need to be considered when using a three-phase VFD
using single-phase power source.
• Depending on the increased DC ripple, sensorless mode may result in poor performance
when operating a three-phase inverter using single-phase power supply.
• If a phase open trip occurs, cancel the input phase open protection bit setting (PRT-05:
Phase Loss Chk).
• Do not allow the current to exceed the single-phase rating. Motor capacity, motor overload
trip, and E-thermal functions must be set to protect motor.
• A reactor is always required. Use a model type that comes with built-in DC reactor. The iS7
200 V 30–75kW and 400 V 280–375 kW products do not have built-in DC reactors. Install an
external AC reactor separately for these model types (Do not install DC reactors externally).

Storage and Disposal

Storage &
Disposal

17 Storage and Disposal

17.1 Storage
If you are not using the product for an extended period, store it in the following way:
• Store the product in the same environmental conditions as specified for operation (refer to
3.1 Installation Considerations on page16.
• When storing the product for a period longer than 3 months, store it between 0˚C and
65˚C, to prevent depletion of the electrolytic capacitor.
• Do not expose the drive to snow, rain, fog, or dust.
• Package the inverter in a way that prevents contact with moisture. Keep the moisture level
below 70% in the package by including a desiccant, such as silica gel.
• If the product is exposed to a humid or dusty environment, separate the product and then
keep it in an adequate environment that is suitable for product operation.

If the inverter has not been operated for a long time, capacitors may lose their charging
characteristics and become depleted. To prevent depletion, turn on the product once a year and
allow the device to operate for 30-60 min. Run the device under no-load conditions.

17.2 Disposal
When disposing of the product, categorize it as general industrial waste. Recyclable materials
are included in the product, so recycle them whenever possible. The packing materials and all
metal parts can be recycled.
