Step1 Front Cover, Control Terminal Cover and Cable Guide

The front cover must be removed to install cables.
1 Slide the front cover downward while pressing and holding the upper-center part of the cover.

2 Remove the cover by lifting it upward from the bottom and moving it away from the front of the
inverter.

Note
If you have installed the remote keypad, remove the plastic cover under the lower-right part of the control
terminal cover, and then connect the remote keypad signal to the RJ-45 connector.

Step 2 Ground Connection

Remove the control terminal cover, and then follow the instructions below to install the ground
connection for the inverter.
3 Locate the ground terminal and connect an appropriately rated ground cable to the terminals.
Refer to 1.5 Cable Selection on page11 to find the appropriate cable specification for your
installation.

4 Connect the other ends of the ground cables to the supply earth (ground) terminal.

Note
Class 3 grounding is required. Resistance to ground must be < 100Ω.

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.

Step3 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 page11 before installing them.

• Tighten terminal screws to their specified torque. Loose terminal screws may allow the cables to
disconnect and cause short circuit or inverter failure. Over tightening terminal screws may damage the
terminals and cause short circuits and malfunctions.
• Use copper cables rated for 600V, 75℃ for power terminal wiring.
• Use copper cables rated for 300V, 75℃ for control terminal wiring.
• When making wiring connections at the power terminals, do not make a bi-wired connection to a
single terminal.
• Power supply cables must be connected to the R and T terminals. Connecting power cables to the U,
V, and W terminals will cause internal damage to the inverter. Connect motors to the U, V, and W
terminals. Phase sequence arrangement is not necessary.

• 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 risqué
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, 75 ℃ pour le câblage de la
borne d’alimentation, et une valeur nominale de 300 V, 75 ℃ pour le câblage de la borne de
commande.
• Ne jamais connecter deux câbles à une borne lors du câblage de l'alimentation.
• Les câblages de l’alimentation électrique doivent être connectés aux bornes R, 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.

R/T AC power input terminal Mains supply AC power connections.
B1/B2(1.5kW~2.2kW) Brake resistor terminals Brake resistor wiring connection.
U/V/W Motor output terminals 3-phase induction motor wiring connections.

Note
• Use STP (Shielded Twisted Pair) cables to connect a remotely located motor with the inverter. Do
not use 3 core cables.
• Ensure that the total cable length does not exceed 165ft (50m).
• 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 and T terminals. Connecting power cables to other
terminals will damage the inverter.
• Use insulated ring lugs when connecting cables to R/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 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.

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 11 before

* If the length (L) of the crimp terminals exceeds 0.5” (12.7mm) after wiring, the control terminal cover may not
close fully.

To connect cables to the control terminals without using crimp terminals, refer to the following
illustration detailing the correct length of exposed conductor at the end of the control cable.

Ensure that there is no debris entered inside the inverter.

Step 5 PNP/NPN Mode Selection
The M100 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 (SW1)
on the control board. Refer to the following information for detailed applications.

Note
• While making wiring connections at the control terminals, ensure that the total cable length does not
exceed 165ft (50m).
• Ensure that the length of any safety related wiring does not exceed 100 ft (30 m).
• Ensure that the cable length between a remote keypad and the inverter does not exceed 1 0ft (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 front cover.
• When making control terminal cable connections, use a small flat-tip screw driver (0.1in wide
(2.5mm) and 0.015in thick (0.4mm) at the tip).

When making control terminal cable connections, ensure that the inverter’s power is turned off.

PNP Mode (Source)
Select PNP using the PNP/NPN selection switch (SW1). 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 24V
internal source. If you are using an external 24V source, build a circuit that connects the external
source (-) and the CM terminal.

NPN PNP

NPN Mode (Sink)
Select NPN using the PNP/NPN selection switch (SW1). CM is the common ground terminal for all
analog inputs at the terminal, and P24 is 24V internal source.

NPN PNP

Step 6 Disabling the EMC Filter for Power Sources with Asymmetrical Grounding

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.

• 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.
• 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.

설치준비 기본조작법기능알람표제어블록도 기본기능 응용기능 모니터기능 보호기능 통신기능

Before using the inverter, confirm the power supply’s grounding system. Disable the EMC filter if the
power source has an asymmetrical grounding connection. Check the location of the EMC filter on/off
screw and attach the plastic washer to the screw under the control terminal block.

• When a normal induction motor is in use, care must be taken not to configure the output pattern away
from a linear V/F pattern. Non-linear V/F patterns may cause insufficient motor torque or motor
overheating due to over-excitation.
• When a user V/F pattern is in use, forward torque boost (Ftb) and reverse torque boost (rtb) do not
operate.

Output Voltage Setting
Output voltage settings are required when a motor’s rated voltage differs from the inverter’s input
voltage. The set voltage becomes the output voltage of the inverter’s base frequency. If the frequency
is higher than the base frequency, and the input voltage is lower than the parameter setting, the input
voltage will become the inverter output voltage.
If this code is set to 0, the inverter corrects the output voltage based on an inactive input voltage.
This feature is used when a motor is operating with a voltage that is lower than the input voltage.

You can use the parameter value displayed on the motor’s rating plate without motor parameter
tuning. Set the MbF (Base frequency), bA12 (Rated slip speed), MrC (Motor-rated current), bA14
(Motor noload current, 40% of motor-rated current) codes to the value displayed on the motor’s rating
plate. If you do not use the value displayed on the motor’s rating plate, each parameter value is set to
the initial value and some features may be limited.
Auto torque boost basically operates with manual torque boost (Ftb, rtb) setting value, and the
additional boost amount is determined according to the following situation.
The output voltage can be adjusted by adding voltage boost to the output voltage using torque current,
when it is too low to start the V/F pattern operation. When the starting torque is too low or too high,
the dr27 and dr28 codes (auto torque boost voltage gains) can be used for adjusting compensation
based on the load.
Set the dr15 code to 1 (Auto torque boost) in the Drive (dr) group to output the voltage based on the
torque boost. You can also change the dr26, dr27, and dr28 parameters.

Use frequency jump to prevent motor operation at mechanical resonance frequencies. When jumping
through a frequency bands while a motor accelerates and decelerates, operation frequencies cannot be
set within the preset frequency jump band and the inverter operates at a constant speed.
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 frequencies used by the frequency jump band.
On the contrary, when a frequency setting is decreased, 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 upper limit value of the frequency band. Then, the frequency will
decrease when the frequency parameter setting exceeds the range of frequencies used by the
frequency jump band.

or DC braking time is set too long.

This feature is disabled if the Ad16 or Ad15 code is set to 0.
Output block time before braking (Ad14): If the inertia of the load is great, or if DC braking
frequency 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 (Ad14).
When the inertia of the load is great and DC braking frequency is set too high, modify the inertia rate
at the bA16 code. The DC braking controller’s controller gain will be changed based on the set value
of the bA16 code.

Dwell frequency: A rated slip frequency that supplies the rated torque to the motor before opening the
mechanical brake of lift-type loads. The rated slip frequency is different from the rated frequency
converted from the rated RPM on the motor rating plate.

AP23: Sets the time to output accumulated errors. When the error is 100%, the time taken for 100%
output is set. When the integral time is set to 1 second, 100% output occurs after 1 second of the error
remaining at 100%. Differences in a normal state can be reduced by the integral time. Adjusting the
value leads to a faster response, but oscillation may occur at the controller.
AP24: Sets the output volume for the rate of change in errors. M100 detects error every 1 ms. When
the differential time is set to 1 ms and the rate of change in errors per sec is 100%, output occurs at 1%
per 10 ms.
AP28: Adds the set target to the PID controller and sets the volume of the target.
AP29, AP30: Limits the output of the controller.
AP20: Selects the PID reference source.
AP02: You can set the unit of the PID reference (AP19) and PID feedback (AP18) to Hz (frequency)
or % (percentage). (AP02 = 0: Hz, AP02 = 1: %)
In65–In69: When one the multi-function input terminal P1–P5 is set to 21 (PID switch operation) and
turn the terminal ON, the PID control is switched to normal PID control where the command
frequency is operated as the PID reference but not as the PID controller output.)
rPM: Converts the feedback volume set at AP21 to motor frequency.
When running the PID switch operation, the output frequency is displayed, but the feedback volume
is not displayed.

1) RS-485 communication is added to the PID feedback group.
2) PID REF (PID reference) value can be checked and configured at AP19.
When AP02 = 0, the unit is set to [Hz]. When AP02 = 1, the unit is set to [%].
3) PID FBK (PID feedback volume) value can be checked at AP18. The unit is identical to the unit of the AP19
parameter value.
4) When the PID switch operation (21, PID operation switched to normal operation) signal is input to the multi-

percentage value is converted and output to the frequency value.
5) Polarity of PID OUT (Normal PID output) is unipolar, and it is limited by AP29 (H-Limit, Frequency jump

1) Main reference is a frequency (Frq=10, Up/Down operation excluded) set at the Frq/bA05 codes in the
Operation group, and the actual output frequency is the main reference and PID OU2 (PID block output).
2) When the PID switching operation is selected, the main reference becomes the actual output frequency.
3) PID OU1, the output in the PID block diagram, is bipolar and the parameter is limited by the AP29 (PID
upper limit) code.
4) PID OU2 is the actual frequency and is limited by the FrM (maxFreq, the maximum frequency) and AP28 (L-
Limit, frequency jump lower limit 1) codes.

Other operations are identical to those using normal PID operation.

PID Sleep & Wake-up
The inverter automatically enters sleep mode and stops operating when the PID controller’s output
frequency is maintained at the sleep frequency (AP38) for sleep delay time (AP37). Monitoring still
operates in the sleep mode, and the inverter wakes up and runs again when deviation between the PID
reference and the feedback volume becomes higher than the wake-up level (AP39).
Sleep mode is disabled when a stop command is input.
This feature can be used, for example, at night when the flow rate to the pump load is low.

This operation is used to prevent fault trips that can occur while the inverter output voltage is
disconnected and the motor is idling.
Because this feature estimates the motor rotation speed based on the inverter output current, it does
not give the exact speed.
You can select a speed search operation from the following four types.

Speed
search
selection

---1 Speed search for general acceleration
--1- Initialization after a fault trip (Pr08=1)
-1-- Restart after instantaneous power interruption
1--- Starting with power-on (Ad10)

Cn72: The amount of current flow is controlled during speed search operation based on the motor’s
rated current (MrC).

Cn73, Cn74: The P/I gain of the speed search controller can be adjusted. The P/I gain are adjusted
according to the characteristics of a load.
OU31, OU32: Outputs the speed search operation state to the external sequence using a multi-
function relay (3ABC).
Example) After an instantaneous power interruption

_
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 control.
t1: If the current increases above the value set at Cn72, the voltage stops increasing and the
frequency decreases.
t2: If the current decreases below the value set at Cn72, the voltage increases again and the
frequency stops decelerating.
When the normal frequency and voltage are resumed, the speed search operation accelerates
the motor back to its frequency reference before the fault trip.
Speed search operation is suitable for loads with high inertia. When the load with high friction force
occurs, stop and restart the inverter.
If operated within the rated output, the M100 series inverter is designed to withstand instantaneous
power interruptions within 15 ms and maintain normal operation.

The DC voltage inside the inverter may vary depending on the output load. If the power interruption
time is longer than 15 ms, a low voltage trip may occur. The instantaneous power interruption
specification is applied when the input voltage is 200–240 VAC.

(Protection)

09 Auto restart count - 0–10 0 count
10 Auto restart delay time after trip - 0.0–60.0 1.0 sec

Auto restart count can be set using the Pr09 code.
An auto restart is used to activate the inverter protection feature and protect the inverter from noise or
other problems, therefore preventing the shutdown of the system.
Pr09: When a trip occurs and the run command is input after the trip, the inverter protection feature is
activated and the inverter restarts automatically after the set time programmed at the Pr10 code. At
each restart, the inverter counts the number of tries and subtracts it from the number set at the Pr09
code until the retry number count reaches 0. The retry number count returns to the original setting
when you manually reset it using the inverter terminal block or the [STOP/RESET] key, and when a
trip does not occur within 30 seconds after an auto restart.
If the inverter stops due to low voltage, emergency stop (Bx), inverter overheating, or hardware
diagnosis, an auto restart is not activated.
The inverter start acceleration automatically after the auto restart delay time set by the Pr10 code. At
auto restart, the acceleration options are identical to those of speed search operation (Cn71–74).

The following graph is an example when the auto restart count is set to 2.

Brake release sequence
During motor stop state, if an operation command is entered, the inverter accelerates up to brake
release frequency (Ad44– 45) in forward or in reverse direction. After reaching brake release
frequency, if motor current reaches brake release current (Ad41), 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 frequency for brake release delay time (Ad42).
Brake engage sequence
If a stop command is sent during operation, the motor decelerates. Once the output frequency reaches
brake engage frequency (Ad47), the motor stops deceleration and sends out a brake engage signal to a
preset output terminal. Frequency is maintained for the brake engage delay time (Ad46) and will
become 0 afterwards.

The external brake control is used only when the control mode is set to V/F steady control and the brake
open frequency is lower than the brake close frequency.

Draw operation is a tension control. This feature allows a constant tension to be applied to the
material that is drawn by a motor-driven device, by fine-tuning the motor speed using operation
frequencies that are proportional to a ratio of the main frequency reference.
The ratio applied to the output frequency differs by the AP70 (Draw operation) parameter setting.

Set the AP70 code to 1, 2, or 3.
If the input value is higher than the analog input’s median value that is determined by the parameter
settings of In08–11, In38–41, In53–56, and In58–61, the value is applied to the output frequency as a
positive value, as much as the ratio set by AP71. If it is lower than the median value, it is applied as a
negative value.

Example of Draw Operation
When the set frequency is 30 Hz, AP70=1(V1: 0 –10 V), AP71=10.0%, and In07–In11 are set to the
factory default settings, the frequency converted to the draw operation is 27 Hz (V1=0 V)–33 Hz
(V1=10 V).
When the AP70 code is set to 1 (V1), the frequency is calculated by the following formula:

• Set the operation command at the Frq/bA05 codes and other frequencies at the AP70 code (Draw
operation).
• For example, the draw operation is disabled if Frq=3 (V1) and AP70=1 (V1).

Information of the current fault trip can be monitored by the nOn code in the Operation group when a
trip occurs during operation.
When you reset the inverter to clear the fault status by using the [STOP/RESET] key or a multi-
function terminal block, the information displayed by the Operation group is moved to the Pr91 code.
At this time, the previous fault information saved at the Pr91 code is moved to the Pr92 code
automatically. Therefore, the most recent trip information is saved in the lowest fault history codes.
If multiple trips occur at the same time, the trip information is saved at a single code in a sequential
order.
The following example details navigating to a different code after viewing a fault.

Pr (Protection) 80 Initial charging circuit trip

protection 1 0 –1 1 bit

The initial charging circuit trip protection function can be used only when input power is 0.4–2.2 kW,
and it does not protect trips due to a relay fusion.
This function activates and protects the inverter when the input power is unstable or an initial charging
circuit trip occurs while supplying power to the inverter. If the ROT continues to occur after turning the
power off and on again, stop using the inverter and contact the retailer or the LSIS customer service
center.
(The inverter may become damaged if you operate the inverter in an initial charging circuit trip status.)

8 RS-485 Communication Features
This section in the user manual explains how to control the inverter with a PLC or a computer over a
long distance using the RS-485 communicationfeatures. RS-485 communication features are
available only for M100 models equipped with advanced I/O. To use the RS-485 communication
features, connect the communication cables and set the communication parameters on the inverter.
Refer to the communication protocols and parameters to configure and use the RS-485
communication features.

8.1 Communication Standards
Following the RS-485 communication standards, M100 products exchange data with a PLC and
computer. The RS-485 communication standards support the Multi-drop Link System and offer an
interface that is strongly resistant to noise. Please refer to the following table for details about the
communication standards.
Item Standard
Communication method/
Transmission type RS-485/Bus type, Multi-drop Link System
Inverter type name M100
Number of connected inverters/
Transmission distance

Maximum of 16 inverters / Maximum 1,200m (recommended distance:
within 700m)
Recommended cable size 2 Pair Shielded Twisted Pair Cable (keep it a safe distance from the
power cable.)
Installation type 1) RJ45 connector (pin 1: S+, pin 8: S-, pin 7: SG) on the I/O board
Power supply Supplied by the inverter– an insulated power source from the inverter’s
power circuit
Communication speed 1,200/ 2,400/ 4,800/ 9,600/ 19,200/ 38,400 bps
Control procedure Asynchronous communications system
Communication system Half duplex system
Character system Modbus-RTU: Binary / LS Bus: ASCII

Item Standard
Stop bit length 1-bit/2-bit
Frame error check 2 bytes
Parity check None/Even/Odd
1) Refer to the following when connecting the communication line:
• Use a 2-pair STP (Shielded Twisted Pair) cable (use
only pin 1: S+, pin 8: S-, and pin 7: SG, pin 1 and pin
8 have to be twisted type) and RJ45 STP plug.
For connections between inverters or extension cables,
use an RJ45 coupler (Y-type LAN coupler that the
STP plug can be attached to).
Use cables, plugs, and couplers that conform to the
LAN standard: CAT5, CAT5e, and CAT6.
• Maintain a safe distance between the communication
line and the power cable.

8.2 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.

설치준비 제품설치 기본조작법기능알람표제어블록도 기본기능 응용기능 전체기능표 통신기능

Communication Line Connection
Make sure that the inverter is turned off completely, and then connect the RS-485 communication line
to the RJ45 connector (pin 1: S+, pin 8: S–, pin 7: SG) of the I/O board. The maximum number of
inverters you can connect is 16. Use a shielded twisted pair cable for communication, and keep it a
safe distance from the power cable during installation.
The maximum length of the communication line is 1,200 meters, but it is recommended to use no
more than 700 meters of communication line to ensure stable communication. Please use a repeater to
enhance the communication speed when using a communication line longer than 1,200 meters or
when using a large number of devices. A repeater is effective when smooth communication is not
available due to noise interference.

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

Setting Communication Parameters
Before proceeding with setting communication configurations, make sure that the communication
lines are connected properly. Turn on the inverter and set the communication parameters.

Note
1 Data cannot be saved when editing data via the common area parameter.
• The data change is reflected temporarily, but the value will return to the previously set value
when resetting or turning off and on the inverter.
• When editing data via each group parameter other than the common area parameter, the data
change will be maintained even after resetting or turning off and on the inverter.
2 The software version in the common area is displayed in hexadecimal numbers, and the software
version in the parameter area is displayed in decimal numbers.
3 The 0x001E PID Feedback parameter in the common area can be written and read in 0.1%
increments regardless of the AP2 PID unit setting parameter, and the amount of feedback that can be
reflected or read is as follows:
• When the maximum frequency is 60.00 Hz and writing 0x0032 (5.0%) to 0x001E:
60.00Hz x 5.0% = 3.00Hz_

10 Troubleshooting
This chapter explains how to troubleshoot a problem when inverter protective functions, fault trips,
warning signals, or a fault occurs. If the inverter does not work normally after following the suggested
troubleshooting steps, please contact the LSIS customer service center.

10.1 Trips
When the inverter detects a fault, it stops the operation (trips) or sends out a warning signal. When a
trip or warning occurs, the keypad displays the information. Users can read the warning message at
Pr91–Pr95. When more than 2 trips occur at roughly the same time, the keypad (basic keypad with 7-
segment display) displays the higher priority fault trip information.
The fault conditions can be categorized as follows:
• Level: When the fault is corrected, the trip or warning signal disappears and the fault is not saved
in the fault history.
• Latch: When the fault is corrected and a reset input signal is provided, the trip or warning signal
disappears.
• Fatal: When the fault is corrected, the fault trip or warning signal disappears only after the user
turns off the inverter, waits until the charge indicator light goes off, and turns the inverter on again.
If the inverter is still in a fault condition after powering it on again, please contact the supplier or
the LSIS customer service center.

Fault Trips
Protection Functions for Output Current and Input Voltage
Keypad
Display Item Type Description

OLt
(Over Load) Latch

Displayed when the motor overload trip is activated and the
actual load level exceeds the set level. Operates when Pr20
is set to a value other than 0.

OCt
(Over
Current)

Latch Displayed when inverter output current exceeds 200% of the
rated current.

Ovt
(Over
Voltage)

Latch Displayed when internal DC circuit voltage exceeds the
specified value.

Lvt
(Low Voltage) Level

Displayed when internal DC circuit voltage is less than the
specified value.

GFt
(Ground Trip) Latch

Displayed when a ground fault trip occurs on the output side
of the inverter and causes the current to exceed the specified
value. The specified value varies depending on inverter
capacity.

EtH
(E-Thermal) Latch

interference, change the input filter time
constant (In07, In52, In57).

The wiring length between the inverter and
the motor is too long.

Ensure that the total cable length between
the inverter and the motor is less than
100 m.

The motor does
not come to a
complete stop
when the inverter
output stops.

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, 75 ℃ pour le câblage de la borne d’alimentation, et une valeur nominale de
300 V, 75 ℃ pour le câblage de la borne de commande.

[Frame B/C (0.4kW-1–2.2kW-1)]

If the ambient temperature is high, and if the maximum carrier frequency for continuous full load
conditions (4 kHz for A Frame 0.1 kW-1/0.2 kW-1 products, 6 kHz for B/C Frame 0.4 kW-1 – 2.2
kW-1 products) is exceeded, a protective feature may be activated to limit the carrier frequency (to 4
kHz / 6 kHz) to prevent damages to the product.
The protective feature will be deactivated and the user-configured carrier frequency will be used
again when the internal temperature becomes low enough for reliable operation.
Before operating the product with a high carrier frequency, refer to the table above to ensure that the
carrier frequency is appropriately set for reliable operation at continuous full load conditions(%).

12.9 Remote Keypad Option
The option consists of a remote keypad and cables (1M, 2M, 3M, 5M).

Unit: mm

Installation
1 Remove the remote keypad cable connection hole and then connect the cable of the remote keypad
to the I/O RJ45 connector.
2 Connect the other end of the cable to the remote keypad.

How to use

1 When connecting the remote keypad, the key and potentiometer on the inverter keypad are ignored
and replaced by the key and potentiometer on the remote keypad.
- Dismount the remote keypad and 2 seconds later, it will return to the original position with the key
and potemtiometer on the inverter keypad.
(If the frequency reference source set to potentiometer, at the time of mounting and dismounting,
the command frequency is instantly switched between the inverter keypad potentiometer and the
remote keypad potemtiometer. Be careful that the motor does not rotate at an unintended frequency.)
- If communication between the inverter and the remote keypad is not established, "E.vEr" is
displayed on the remote keypad 7-Seg.
2 With the remote keypad connected to the inverter, parameter settings saved in the inverter can be
copied to the remote keypad by setting the dr 85 to 1.
- "R-UL" is displayed on the 7-Seg keypad during upload. When the save is complete, the text
disappears and the main screen is displayed.
- If there is an error such as communication error during upload, "FAIL" warning message will be
displayed for 3 seconds and the operation to save the parameter on the remote keypad will fail.
3 With the remote keypad connected to the other inverter of same series, parameter settings saved in
the remote keypad can be copied to the inverter by setting the dr 86 to 1.
- "W-dL" is displayed on the 7-Seg keypad during saving. When the save is complete, the text
disappears and the main screen is displayed.
- At this time, if the model name of the inverter is wrong or the version of the parameter code of the
inverter is wrong or if an error such as remote keypad communication error occurs, a warning
message "FAIL" is displayed for 3 seconds and the parameter is set to inverter Will fail.
