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 high voltage terminals or 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 charge long after the power supply has been turned off. Use a
multi-meter to make sure that there is no voltage before working on the inverter, motor or
motor cable.
• Supply earthing system: TT, TN, not suitable for corner-earthed systems
• 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.iii
Safety Information
• 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.
• The inverter is designed for 3-phase motor operation. Do not use the inverter to operate a
single phase motor.
• Do not place heavy objects on top of electric cables. Doing so may damage the cable and
result in an electric shock.
Note
Maximum allowed prospective short-circuit current at the input power connection is defined
in IEC 60439-1 as 100 kA. LSLV-H100 is suitable for use in a circuit capable of delivering
not more than 100kA RMS at the drive’s maximum rated voltage, depending on the
selected MCCB. RMS symmetrical amperes for recommended MCCB are the following
table.
Remarque
Le courant maximum de court-circuit présumé autorisé au connecteur d’alimentation
électrique est défini dans la norme IEC 60439-1 comme égal à 100 kA. Selon le MCCB
sélectionné, la série LSLV-H100 peut être utilisée sur des circuits pouvant fournir un
courant RMS symétrique de 100 kA maximum en ampères à la tension nominale
maximale du variateur. Le tableau suivant indique le MCCB recommandé selon le courant
RMS symétrique en ampères.

1.3 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

search. 50 ℃ 75% of the rated current of the drive if possible)
Ambient Humidity 95% relative humidity (no condensation)
Storage Temperature - 4–149 F (-20–65 ℃)
Environmental Factors An environment free from corrosive or flammable gases, oil residue
or dust
Altitude
Maximum 3,280 ft (1,000m) above sea level for standard operation.
After that the driver rated voltage and the rated output current
derating by 1% for every extra 328 ft (100m) up to 13,123 ft
(4,000m).
Vibration less than 1.0 G (9.8m/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.
Do not allow the ambient temperature to exceed the allowable range while operating the
inverter.Preparing the Installation
11
1.4 Selecting and Preparing a Site for Installation
When selecting an installation location consider the following points:
• The inverter must be installed on a wall that can support the inverter’s weight.
• The location must be free from vibration. Vibration 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 and with sufficient clearance around the inverter to
allow air to circulate. The illustrations below detail the required installation clearances.Preparing the Installation
12
• 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 the ventilation louver. The cooling fan must
be positioned to efficiently transfer the heat generated by the operation of the inverter.
• If you are installing multiple inverters in one location, arrange them side-by-side and
remove the vent covers. Use a flat head screwdriver to remove the vent covers. Only

Installing the Inverter
2.2 Enabling the RTC (Real-Time Clock) Battery
The H100 series inverter comes from the factory with a CR2032 lithium-manganese battery
pre-installed on the I/O PCB. The battery powers the inverter’s built-in RTC. The battery is
installed with a protective insulation strip to prevent battery discharge; remove this
protective film before installing and using the inverter.
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.
Follow the instructions below to remove the protective insulation strip and enable the RTC
feature on the H100 series inverters.
1 Turn off the inverter and make sure that DC link voltage has dropped to a safe level.

2.3 Cable Wiring
Open the terminal cover, remove the cable guides, and then install the ground connection
as specified. Complete the cable connections by connecting an appropriately rated cable to
the terminals on the power and control terminal blocks.
Read the following information carefully before carrying out wiring connections to the
inverter. All warning instructions must be followed.
• Install the inverter before carrying out wiring connections.
• Ensure that no small metal debris, such as wire clippings, remain inside the inverter. Metal
debris in the inverter may cause inverter failure.
• Tighten terminal screws to their specified torque. Loose terminal block screws may allow
the cables to disconnect and cause a short circuit or inverter failure. Refer to page 577.
• 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 re-wire 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 wiring connections. The inverter may hold a high voltage electric charge long
after the power supply has been turned off.
• The accessible connections and parts listed below are of protective class 0. It means that
the protection of these circuits relies only upon basic insulation and becomes hazardous in
the event of a failure of the basic insulation. Therefore, devices connected to these circuits
must provide electrical-shock protection as if the device was connected to supply mains
voltage. In addition, during installation these parts must be considered, in relation with
electrical-shock, as supply mains voltage circuits.

Step 3 Power Terminal Wiring
The following illustration shows the terminal layout on the power terminal block. Refer to the
detailed descriptions to understand the function and location of each terminal before making
wiring connections. Ensure that the cables selected meet or exceed the specifications in 1.5
Cable Selection on page 14 before installing them.Installing the Inverter
30
• Apply rated torques to the terminal screws. Loose screws may cause short circuits and
malfunctions. Tightening the screw too much may damage the terminals and cause short
circuits and malfunctions.
• Use copper wires only with 600 V, 75 ℃ rating for the power terminal wiring, and 300 V,
75 ℃ rating for the control terminal wiring.
• Power supply wirings must be connected to the R, S, and T terminals. Connecting them to
the U, V, W terminals causes internal damages to the inverter. Motor should be connected
to the U, V, and W Terminals. Arrangement of the phase sequence is not necessary.
• Equipment must only be fitted to the closed electric operating areas.
Attention
• Appliquer des couples de marche aux vis des bornes. Des vis desserrées peuvent
provoquer des courts-circuits et des dysfonctionnements. Ne pas trop serrer la vis, car
cela risque d’endommager les bornes et de provoquer des courts-circuits et des
dysfonctionnements.
• Utiliser uniquement des fils de cuivre avec une valeur nominale de 600 V, 90 ℃ pour
le câblage de la borne d’alimentation, et une valeur nominale de 300 V, 75 ℃ pour le
câblage de la borne de commande.
• Les câblages de l’alimentation électrique doivent être connectés aux bornes R, S et T.
Leur connexion aux bornes U, V et W provoque des dommages internes à l’onduleur.
Le moteur doit être raccordé aux bornes U, V et W. L’arrangement de l’ordre de phase
n’est pas nécessaire.31

Installing the Inverter
Note
• Apply a DC input to the P2 (+) and N (-) terminals to operate the inverter on DC voltage
input.
• Use STP (Shielded Twisted Pair) cables to connect a remotely located motor with the
inverter. Do not use 3 core cables.
• Make sure that the total cable length does not exceed 492 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 malfunction of equipment connected to the inverter. • Voltage drop is calculated by using the following formula: • Voltage Drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current (A)] / 1000 • Use cables with the largest possible cross-sectional area to ensure that voltage drop is minimized over long cable runs. Lowering the carrier frequency and installing a micro surge filter may also help to reduce voltage drop. Distance < 165 ft (50 m) < 330 ft (100 m) > 330 ft (100 m)
Allowed Carrier Frequency <15 kHz <5 kHz <2.5 kHz 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. • 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 to 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 phaseadvanced condensers, surge protection, or electronic noise filters on the output side of the inverter. • Connect the MC to the output of the inverter and avoid MC ON / OFF state during operation. (It may cause inverter trip and burn-out.)Installing the Inverter 36 Step 4 Control Terminal Wiring The illustrations below show the detailed layout of control wiring terminals and control board switches. Refer to the detailed information provided below and 1.5 Cable Selection on page 14 before installing control terminal wiring and ensure that the cables used meet the required specifications.

Note • While making wiring connections at the control terminals ensure that the total cable length does not exceed 165 ft (50 m). • Ensure that the length of any safety related wiring does not exceed 100 ft (30 m). • Ensure that the cable length between the keypad and the inverter does not exceed 10 ft (3.04 m). Cable connections longer than 10 ft (3.04 m) may cause signal errors. • Use ferrite material to protect signal cables from electro-magnetic interference. • Take care when supporting cables using cable ties, to apply the cable ties no closer than 6 inches from the inverter. This provides sufficient access to fully close the terminal cover.41 Installing the Inverter Step 5 PNP/NPN Mode Selection The H100 inverter supports both PNP (Source) and NPN (Sink) modes for sequence inputs at the terminal. Select an appropriate mode to suit requirements using the PNP/NPN selection switch (SW2) on the control board. Refer to the following information for detailed applications. PNP Mode (Source) Select PNP using the PNP/NPN selection switch (SW2). Note that the factory default setting is NPN mode. CM is the common ground terminal for all analog inputs at the terminal, and P24 is 24 V internal source. If you are using an external 24 V source, build a circuit that connects the external source (-) and the CM terminal.Installing the Inverter 42 NPN Mode (Sink) Select NPN using the PNP/NPN selection switch (SW2). Note that the factory default setting is NPN mode. CM is the common ground terminal for all analog inputs at the terminal, and P24 is 24 V internal source.43 Installing the Inverter Step 6 Disabling the EMC Filter for Power Sources with Asymmetrical Grounding H100, 400 V 0.75–55 kW, 110~500kW(3 phase) inverters have EMC filters built-in and activated as a factory default design. An EMC filter prevents electromagnetic interference by reducing radio emissions from the inverter. EMC filter use is not always recommended, as it increases leakage current. If an inverter uses a power source with an asymmetrical grounding connection, the EMC filter must be turned off. Asymmetrical Grounding Connection One phase of a delta connection is grounded (TN Systems) Intermediate grounding point on one phase of a delta connection (TN Systems) The end of a single phase is grounded (TN Systems) A 3-phase connection without grounding (TN Systems) • Do not activate the EMC filter if the inverter uses a power source with an asymmetrical grounding structure (corner-earthed systems), for example a grounded delta connection. Personal injury or death by electric shock may result. • Wait at least 10 minutes before opening the covers and exposing the terminal connections. Before starting work on the inverter, test the connections to ensure all DC voltage has been fully discharged. Personal injury or death by electric shock may result. Before using the inverter, confirm the power supply’s grounding system. Disable the EMC filter if the power source has an asymmetrical grounding connection.Installing the Inverter 44 Disabling the Built-in EMC Filter for 0.75–30 kW (3–Phase) Inverters Refer to the figures below to locate the EMC filter on/off terminal and replace the metal bolt with the plastic bolt. If the EMC filter is required in the future, reverse the steps and replace the plastic bolt with the metal bolt to reconnect the EMC filter. If the EMC filter is required in the future, reverse the steps and replace the plastic bolt with the metal bolt to enable the EMC filter.45 Installing the Inverter Disabling the Built-in EMC Filter for 37–55 kW (3–Phase) Inverters Follow the instructions listed below to disable the EMC filters for the H100 inverters rated for 37–55 kW. 1 Remove the EMC ground cover located at the bottom of the inverter. 2 Remove the EMC ground cable from the right terminal (EMC filter-ON / factory default), and connect it to the left terminal (EMC filter-OFF / for power sources with asymmetrical grounding).

3 Set a frequency reference, and then check the following:
• If V1 is selected as the frequency reference source, does the reference change
according to the input voltage at VR?
• If V2 is selected as the frequency reference source, is the voltage/current selector
switch (SW4) set to ‘voltage’, and does the reference change according to the input
voltage?
• If I2 is selected as the frequency reference source, is the voltage/current selector
switch (SW4) set to ‘current’, and does the reference change according to the input
current?
4 Set the acceleration and deceleration time.
5 Start the motor and check the following:
• Ensure that the motor rotates in the correct direction (refer to the note below).
• Ensure that the motor accelerates and decelerates according to the set times, and
that the motor speed reaches the frequency reference.
Note
If 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.51
Installing the Inverter
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

Operation Mode at Power Recovery
If a power interruption occurs during inverter operation in the OFF or HAND mode, the
inverter halts the operation with low voltage fault trip. Then, when the power is recovered,
the inverter turns on in OFF mode.
If the inverter was operating in AUTO mode at the time of the low voltage trip following the
power interruption, the inverter turns on in AUTO mode, and the operation may vary
depending on the inverter’s ‘PowerOn Resume’ and ‘Power-on run’ settings.
Note
• To operate the inverter using the keypad in AUTO mode, set DRV-06 (CMD Source) to
‘KeyPad’ and press the AUTO key to enter AUTO mode. Then, press the AUTO key on
the keypad once again to start the inverter operation.
• If a fault trip occurs during an operation in the AUTO or HAND mode, the inverter can
be reset by pressing the OFF key. After the reset, the fault trip is released and the
inverter enters OFF mode.86
Learning Basic Features
• If a fault trip occurs during an operation in the AUTO or HAND mode, the inverter can
be reset using the reset signal from the multi-function input terminal as well. In this
case, the inverter turns back on in AUTO mode after the fault trip is released.
Use caution when the inverter is set to operate in AUTO mode by commands over
communication, and if COM-96 (PowerOn Resume) is set to ‘yes’, as the motor will begin
rotating when the inverter starts up, without additional run commands.
4.2 Setting Frequency Reference
The H100 inverter provides several methods to setup and modify a frequency reference for
an operation. The keypad, analog inputs [for example voltage (V1, V2) and current (I2)

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 analog
maximum input (60 Hz), the output frequency will increase or decrease by91

0.6 Hz per 0.1 V difference.
When the analog input is increased, an increase to 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.

Note
• To prevent a repeat fault trip from occurring, set CON-71 (speed search options) bit 4 the
same as bit 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 ‘reset and
restart’ enabled, the terminal block command must be first turned off, and then turned on
again to begin the inverter’s operation.
Use caution when operating the inverter with Power-on Run enabled as the motor will begin
rotating when the inverter starts up.110
Learning Basic Features
4.9 Reset and Restart
Reset and restart operations can be setup for inverter operation following a fault trip, based
on the terminal block operation command (if it is configured). When a fault trip occurs, the
inverter cuts off the output and the motor will free-run. Another fault trip may be triggered if
the inverter begins its operation while motor load is in a free-run state. In PRT-08, bit 1 sets
the option for all the fault trips, other than low voltage trips, and bit 2 sets the option for low
voltage trips. PRT-10 sets the delay time for restart (the time for the inverter to 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 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 certain period of time.

4.10 Setting Acceleration and Deceleration Times
4.10.1 Acc/Dec Time Based on Maximum Frequency
Acc/Dec time values can be set based on maximum frequency, not on inverter operation
frequency. To set Acc/Dec time values based on maximum frequency, set BAS- 08
(Acc/Dec reference) in the Basic group to ‘0 (Max Freq)’.
Acceleration time set at DRV-03 (Acceleration time) refers to the time required for the
inverter to reach the maximum frequency from a stopped (0 Hz) state. Likewise, the value

Code Description
ADV-03 Acc S
Start
Sets the gradient level as acceleration starts when using an S-curve,
Acc/Dec pattern. ADV-03 defines S-curve gradient level as a percentage,
up to half of total acceleration.
If the frequency reference and maximum frequency are set at 60 Hz and
ADV-03 is set to 50%, ADV-03 configures acceleration up to 30 Hz (half
of 60 Hz). The inverter will operate S-curve acceleration in the 0-15 Hz
frequency range (50% of 30 Hz). Linear acceleration will be applied to the
remaining acceleration within the 15–30 Hz frequency range.
ADV-04 Acc S End
Sets the gradient level as acceleration ends when using an S-curve
Acc/Dec pattern. ADV-03 defines S-curve gradient level as a percentage,
above half of total acceleration.
If the frequency reference and the maximum frequency are set at 60 Hz
and ADV-04 is set to 50%, setting ADV-04 configures acceleration to
increase from 30 Hz (half of 60 Hz) to 60 Hz (end of acceleration). Linear

4.14.2 Auto Torque Boost
Set DRV-15 to ‘Auto 1’ or ‘Auto 2’ to select the type of torque boost. While manual torque
boost adjusts the inverter output based on the setting values regardless of the type of load
used in the operation, auto torque boost enables the inverter to automatically calculate the
amount of output voltage required for 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 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
5.21 Auto Tuning on page 210.
4.14.3 Auto Torque Boost 2 (No Motor Parameter Tuning
Required)
By adjusting the auto torque boost voltage gain set at DRV-15 (ATB Volt Gain), automatic
torque boost may be operated without tuning the motor-related parameter values. The
DRV-15 (ATB Volt Gain) value is used to adjust the amount of compensation required for
each load. It prevents stalls or overcurrent fault trips at start up.

4.15 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, when the input voltage is lower than the parameter setting, the input voltage will
be the inverter output voltage.

inertia, DC braking will stop the motor, allowing the motor to accelerate from a stopped
condition. 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 the

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
4.17 Stop Mode Setting

ADV-14 DCBlock Time
Set the time to block the inverter output before DC braking. If the inertia of
the load is great, or if DC braking frequency (ADV-17) is set too high, a fault
trip may occur due to overcurrent conditions when the inverter supplies DC
voltage to the motor. Prevent overcurrent fault trips by adjusting the output
block time before DC braking.
ADV-15 DCBrake Time Set the time duration for the DC voltage supply to the motor.
ADV-16 DCBrake Level
Set the amount of DC braking to apply. The parameter setting is based on
the rated current of the motor.
ADV-17 DCBrake Freq
Set 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, dwell operation will not work and DC braking will start
instead.131
Learning Basic Features
• Note that the motor can overheat or be damaged if excessive amount of DC braking is
applied to the motor or DC braking time is set too long.
• 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.
4.17.3 Free Run Stop
When the Operation command is off, the inverter output turns off, and the load stops due to
residual inertia.
Group Code Name LCD Display Parameter Setting Setting Range Unit
ADV 08 Stop Method Stop mode 2 Free-Run 0–4 -
Note that 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 if the inverter output is blocked132
Learning Basic Features
4.17.4 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.
• To prevent overheating or damaging the motor, do not apply power braking to the 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 and operate.
• Note that if deceleration time is too short or inertia of the load is too great, an overvoltage
fault trip may occur.
• Note that if a free run stop is used, the actual deceleration time can be longer than the preset deceleration time.

4.18.3 Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies. The inverter will avoid
identified ranges during acceleration and deceleration. Operation frequencies cannot be set
within the pre-set frequency jump band.
When a frequency setting 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

The table above lists the available calculated conditions for the main and auxiliary
frequency references. Refer to the table to see how the calculations apply to an example
where the DRV-06 Frq Src code has been set to ‘0 (Keypad-1)’, and the inverter is
operating at a main reference frequency of 30.00 Hz. Signals at -10 to +10 V are received
at terminal V1, with the reference gain set at 5%. In this example, the resulting frequency
reference is fine-tuned within the range of 27.00–33.00 Hz [Codes IN-01–16 must be set to
the default values, and IN-06 (V1 Polarity), set to ‘1 (Bipolar)’].144

5.2 Jog Operation
The jog operation allows for a temporary control of the inverter. You can enter a jog
operation command using the multi-function terminals or by using the [ESC] key on the
keypad.
The jog operation is the second highest priority operation, after the dwell operation. If a jog
operation is requested while operating the multi-step, up-down, or 3-wire operation modes,
the jog operation overrides all other operation modes.
5.2.1 Jog Operation 1-Forward Jog by Multi-function Terminal

For jog operation 1, an operation command must be entered to start 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 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.

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 constant speed operation begins when both 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 in the following conditions: the operation command (Fx or
Rx) is off, a fault trip occurs, or the power is off.
When the operation command is turned on again, or when the inverter
regains the power source or resumes to a normal operation from a
fault trip, it resumes operation at the saved frequency. To delete the
saved frequency, use the multi-function terminal block. Set one of the
multi-function terminals to 22 (U/D Clear) and apply signals to it during
constant speed operation. The saved frequency and the up-down
operation configuration will be deleted.152

5.6 Dwell Operation
The dwell operation is used to maintain torque during the application and release of the
mechanical brakes on lift-type loads. Inverter dwell operation is based on the Acc/Dec dwell
frequency and the dwell time set by the user. The following points also affect dwell
operation.
• Acceleration Dwell Operation: When an operation command runs, 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 acceleration time and the operation
speed that was originally set.
• Deceleration Dwell Operation: When a stop command is run, 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 deceleration time that was originally set, then
the operation stops.

5.8 PID Control
PID 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 speed by monitoring the current speed levels of the
equipment or machinery being controlled. Control maintains
consistent speed or operates at the target speed.
Pressure Control
Controls pressure by monitoring the current pressure levels of
the equipment or machinery being controlled. Control maintains
consistent pressure or operates at the target pressure.
Flow Control
Controls flow by monitoring the current amount of flow in the
equipment or machinery being controlled. Control maintains
consistent flow or operates at a target flow.
Temperature Control
Controls temperature by monitoring the current temperature
levels of the equipment or machinery to be controlled. Control
maintains a consistent temperature or operates at a target159

• The following are the variables used in PID operation, and how they are calculated:
- Unit MAX = PID Unit 100% (PID-68)
- Unit Min = (2xPID Unit 0% (PID-67)–PID Unit 100%)
- Unit Default = (PID Unit 100%-PID Unit 0%)/2
- Unit Band = Unit 100%-Unit 0%
• PID control may be utilized for the following operations:
Soft fill, auxiliary PID reference compensation, MMC, flow compensation, pipe breakage
detection
• During a PID operation, the PID output becomes the frequency reference. The inverter
accelerates or decelerates to the frequency reference based on the Acc/Dec times.

5.8.2 Soft Fill Operation
A soft fill operation is used to prevent excessive pressure from building in the pipe system at
the initial stage of a pump operation. When the operation command is given, a general
acceleration (without PID control) begins and continues until the output reaches the
frequency set at AP1-21, for the time set at AP1-22. Then, the soft fill PID operation is
performed unless the feedback value has reached the value set at AP1-23 (Soft Fill Set
value). The soft fill PID operation continues until the feedback or the soft fill PID reference
value reaches the value set at AP1-23 (Soft Fill Set value). When the soft fill operation ends,
a normal PID operation starts.

if the PID reference or feedback exceeds the value set at AP1-23 during
the pre-PID operation, a normal PID operation starts immediately.174

Soft Fill Set
In general, a PID operation starts when the feedback volume (controlled
variables) of PID controller exceeds the value set at AP1-23. However, if
AP1-22 (Pre-PID Delay) is set, the feedback after the set time becomes
the default value for the soft fill PID reference, and the inverter starts the
soft fill operation.
When the feedback or the Soft Fill PID Reference exceeds the Soft Fill Set
value, the soft fill operation ends and a normal process PID operation
begins.

However, note that if the difference between the Soft Fill PID Reference
value and the feedback value is greater than the value set at AP1-26 (Fill
Fdb Diff value), the Soft Fill PID Reference value does not increase.
When a PID process is performed after the soft fill PID operation, the PID Reference value
becomes the PID-11 PID Ref1 Set value.175

5.8.3 PID Sleep Mode
If an operation continues at a frequency lower than the PID operation conditions, a boost
operation is performed to extend sleep mode by raising the PID Reference, and then the
inverter enters PID sleep mode. In PID sleep mode, the inverter resumes PID operation
when the PID feedback falls below the PID Wakeup level and maintains the condition for
the time set at AP1-09 (PID WakeUp1 DT) or AP1-13 (PID WakeUp2DT).
Note
PID Wakeup level may be calculated using the following formula:
PID Wakeup Level = PID-04 (PID Ref Value)–AP1-10 (PID WakeUp1Dev) or, PID-04 (PID Ref
Value) - AP1-14 PID (WakeUp2Dev).
Two sets of configurations are available in PID sleep mode for sleep mode frequency, sleep
mode delay time, wakeup variation, and wakeup delay time. One of the two configurations
may be selected depending on the multi-function input terminal configuration and input
conditions.

5.10 Damper Operation
A damper is a device that controls the flow in a ventilation system. If a fan and a damper are
used together in a system, the inverter may be configured to operate according to the
damper’s operation status. During a damper operation, one of the relay outputs OUT-31–35
(Relay 1–5) may be set to ‘33 (Damper Control)’ to output a signal based on the damper’s
operation status. One of the multi-function terminal inputs (IN-65–71) may also be set to ‘45
(Damper Open)’ to receive the damper status input. The inverter starts operating when both
the run command and the damper open signal are turned on (relay output setting at OUT-
31–35 is not necessary).
When the time difference between the inverter run command and the damper open signal
exceeds the delay time set at AP2-45 (Damper DT), damper error (Damper Err) occurs. If
the damper open relay output and damper control input are set at the same time, and if the
damper open signal is not received until the time set at AP2-45 (Damper DT) is elapsed
(when the inverter is not operating), damper error (Damper Err) occurs.

Sets the maximum compensation volume. This function is based on a PID
operation. The volume is given the same unit used for the PID reference.
Longer pipes cause the actual pressure to decrease, which in turn increases the difference
between the pressure reference and the actual pressure. When the pipe lengths are equal
in two different systems, more pressure loss is caused in the system with greater flow. This
explains the pressure difference between (A) and (B) in the figure (when the flows are
different). To compensate for the pressure loss above, the value of AP1-31 is set to the
maximum volume of compensation when the inverter has the maximum frequency, and
adds to the PID reference after calculating compensation volume based on the output
frequency.

steps (Fx/Rx) switch, the inverter waits at a stop state for the time set at AP2-21 before
going on with the next step. One step in the forward direction and another step in the

5.17 Load Tuning
Load tuning refers to an operation that detects the load applied to a specific section of the
inverter operation (current and voltage) and creates an ideal load curve for the under load
and pump clean operations. The two set points to define the section are user-definable, and
are set at 50% and 85% of the base frequency (DRV-18 Base Freq) by default. The load
tuning result values are saved at codes AP2-2–AP2-10. These values are user definable as
well.
The minimum set point for the load tuning begins at 15% of the base frequency (DRV-18
Base Freq), and the maximum set point can be set up to the base frequency. If the
frequency limit is set to ‘1 (Yes)’ at ADV-24 (Freq Limit), the range is limited within the
frequencies set at ADV-25 (Freq Limit Lo) and ADV-26 (Freq Limit Hi).

AP2-11 Load Curve Cur
AP2-12 Load Curve
PWR
Monitors the load curve value set at AP2-1 (Load Tune) based on
the current output frequency.
When a load tuning is performed, the inverter measures for 10 seconds the motor current
and power, at the frequencies set at AP2-02 and AP2-09. The motor current and power
values measured here are used to generate an ideal load curve.
Note
Load tuning is not available while the inverter is operating.202
Learning Advanced Features
• If the frequencies for AP2-02 (Low Freq) and AP2-08 (High Freq) are set too close to each
other, the resulting load curve may not reflect the actual (ideal) load curve. Therefore, it is
recommended that you keep the AP2-02 and AP2-08 frequencies as close to the factory
defaults as possible.
• If a secondary motor is in use, note that the existing load curve for the main motor will be
applied to the secondary motor unless a load tuning has been performed for the secondary
motor.
5.18 Level Detection
When the inverter is operating at or above the frequency set at PRT-74 (LDT Level), this
function is used to triggers a fault trip or sets a relay output if the source value is out of the
range of the user-defined values. If the reset restart feature is turned on, the inverter
continues to operate based on the run command after the LDT fault trip is released.

If the source is detected below the set level, it must be adjusted to be
above the ‘LDT Level + LDT Band Width’ value to release the level
detection fault trip.
If the source is detected above the set level, it must be adjusted to be
below the ‘LDT Level - LDT Band Width’ value to release the level

PRT-77 LDT
Restart DT
If PRT-08 (RST restart) is set to ‘YES,’ the inverter restarts after the time
set at PRT-76 elapses when an LDT trip is released. The LDT Restart
operates each time an LDT trip is released.
If PRT-77 is set to any other value than ‘0’ and the inverter is operating in
HAND mode, the inverter resets and the LDT trip is released. However,
the inverter stays in OFF mode and does not restart the operation
instantly.

If an LDT trip occurs, the inverter automatically restarts after the time set
in PRT-77 (LDT Restart DT) has elapsed. The PRT-97 is incremented by
1 each time it is automatically restarted.
When the value of PRT-97 becomes equal to PRT-96, it does not try to
restart automatically.
The LDT trip will be restarted within the time set in PRT-98 after auto
restart
If not, PRT-97 is initialized to 0.
OUT-31–35
Relay 1–5
Sets one of the output relays to ‘32 (LDT)’ to monitor the level detection
status.206
Learning Advanced Features

As shown in the figure above, level detection can be carried out (relay output is ‘on’) as the
output frequency is above PRT-76 and the detection value is greater than the value of PRT-
74. The LDT operation is released if the value is less than the value subtracted from the value of
band of, when the value of the feedback is set from PRT-74 to PRT-75.
• The LDT operation is carried out if the inverter operation is above PRT-74.
• Modify PRT-74 and PRT-75 appropriately when modifying LDT Source of PRT-71.
• PRT-74 and PRT-75 become default value if the LDT Source is modified.
• PRT-77 (Restart DT) and PRT-08 (RST restart) features operate separately.
• The inverter waits until the delay time set at PRT-73 (LDT Dly Time) before it operates
based on the setting in LDT-70 when the level detection time condition is met.
5.19 Pipe Break Detection
This function detects Pipe Breaks while the PID operation is on. The fault trip or a warning

In the graph above, Pipe Break occurs if the feedback is smaller than the value calculated
by multiplying the two values set at PID-04 and PRT-61(PID-04 x PRT-61) at the inverter’s
maximum output (when PID output is the maximum set value, or the inverter is running at
the frequency set at DRV-20).

IN-65–71 P1–7 Define Performs the Pre Heat function if the Pre Heat (44) terminal is set.
The initial heating function continually operates when the set multi-function input terminal is
on and until the inverter command is on. If an inverter command is input while the initial
heating function is operating, the inverter starts operation immediately.209
Learning Advanced Features
The initial heating operation starts to run after an inverter operation stops, when the initial
heating function’s terminal input is on after the inverter operation command is off.
The diagram above shows the operation waveform related to AP2-50 DC Inj Delay T. The
Pre Heat function performs when the inverter stop mode is set to Free Run and the Pre
Heat signal is supplied. Then, if the inverter operation command is on, the inverter
maintains acceleration and a fixed frequency. If the inverter operation command is off, the
motor is in Free Run and the Pre Heat operations starts after the time amount set in AP2-
50.
• If the value for AP2-48 Pre Heat Curr is above the rated motor current value, it is limited by
the rated motor current value.
• If the value for AP2-48 Pre Heat Curr is too high or the DC current output time is too long,
the motor may overheat or be damaged and the Inver IOLT may also malfunction. Reduce
the DC output current amount and DC output time to prevent from such damages.210

motor is rotating, including stator resistance
(Rs), no-load current (Noload Curr), rotor
time constant (Tr), etc. Since the motor is

Measures all parameters while the motor is
in the stopped position, including stator
resistance (Rs), no-load current (Noload
Curr), rotor time constant (Tr), etc. Since the
motor is not rotating while the parameters
are measured, the measurements are not
affected when the load is connected to the
motor spindle. However, when measuring
parameters, do not rotate the motor spindle
on the load side.

Displays motor parameters measured by auto tuning. For
parameters that are not included in the auto tuning measurement
list, the default setting will be displayed.
• Perform auto tuning ONLY after the motor has completely stopped running.
• Auto tuning operates when the inverter’s auto mode is off.
• Before you run auto tuning, check the motor pole number, rated slip, rated current, rated
voltage, and efficiency on the motor’s rating plate and enter the data. The default
parameter setting is used for values that are not entered.
• When measuring all parameters after selecting 2 ( All-static type) at BAS-20: compared
with rotation type auto tuning where parameters are measured while the motor is rotating,
parameter values measured with static auto tuning may be less accurate. Inaccuracy of the
measured parameters may degrade the performance of operations. Therefore, run statictype auto tuning by selecting 2 (All) only when the motor cannot be rotated (when gearing
and belts cannot be separated easily, or when the motor cannot be separated mechanically
from the load).
• If auto tuning operates without wiring the motor, ‘Rs Tune Err’ or ‘Lsig Tune Err’ warning
messages are displayed. It can be reset if you press ‘STOP/RESET’ button of the keypad.214

5.22 Time Event Scheduling
Time Event function enables the user to operate the inverter using the RTC (Real-Time
Clock) feature at certain times that the user would like to set. An RTC battery is installed on
the I/O board of the H100 inverter, and it lasts approximately 25,800 hours with the inverter
turned off, and 53,300 hours with the inverter turned on.
To use the Time Event, set the current date and time. Three parameters need to be set to
configure the Time event feature: Time Period Module, Time Event, and Exception Date.
Time Period Description
Time Period Used to set the time of operation.
Time Event Used to set the time of operation.
Exception Date Used to specify the exception date. Exception date has the highest priority.
4 Time period Module types, 8 Time Event Module types, and 8 Exception day types can be
used to configure time events. The Time Event function works based on a series of
configuration using the modules listed in the table above.
