Installation Considerations
• Selecting the installation site
- The location must be free from vibration, and the inverter must be installed on a wall that can support the inverter’s weight.
- 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. 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.
• If you are installing multiple inverters in one location, arrange them side-by-side and remove the top covers.
The top covers MUST be removed for side-by-side installations. Use a flat head screwdriver to remove the top covers.
(DIN rail installation is available.)

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.
• 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.
* The ambient temperature is the temperature measured at a point 2” (5 cm) from the surface of
the inverter.

Installation Quick Guide
Basic Commissioning
• In this step the motor is checked for proper direction
and operation. This test is to be performed solely
from the keypad. Apply power to the drive after all the
electrical connections have been made and protective
convers have been reattached.
• Please go through the following direction to run the
motor.
• Observe the motor’s rotation from the load side and
ensure that the motor rotates counterclockwise
(forward).
• If the motor rotation is not correct, change the
wiring of the motor. (ex. U-V-W > V-U-W)
• This step shows how to setup the sequence and
reference method of the drive. The sequence method
determines how the drive receives its start and stop
command and the reference method determines how
the speed of the motor is controlled. Make sure all
protective covers have been reattached and power is
turned on.

Question: The motor does not rotate and the output current is too high at start.
• Cause: the load is too high. It can be solved by using manual/auto torque boost and changing some parameters.
Question: The motor makes humming sound or loud noises.
• Answer: Slightly increase or decrease the carrier frequency in Cn04.
Question: When the drive is running, the Earth-Leakage Circuit Breaker(ELCB) is activated.
• Cause: The ELCB will disconnect the power if leakage current flows to grounding during drive operation.
• Answer1: Connect the drive to grounding terminal.
• Answer2: Check if the ground resistance is less than 100Ωfor 200V class.
• Answer3: check the capacity of ELCB and connect it to the drive according to the rated current of the drive.
• Answer4: reduce the carrier frequency in Cn-04.
• Answer5: Attempt to keep the cable distance from the drive to motor short as possible.
Question: How do I reset the drive back to factory default settings?
•
Answer: Set CF-93 to 1 (All groups) and press the [ENT] key. CF-93 is displayed again when the initialization has been completed.
Question: How do I adjust the time it takes the motor to speed up or down?
• Answer: Adjust the acceleration time in ACC and deceleration time in dEC.
Question: How do I prevent the drive from tripping on an OV fault (overvoltage) while the motor is ramping down?
• Answer1: Increase the deceleration time in dEC.
• Answer2: Activate flux braking in Pr-50. Activate the very first bit on the left.
• Answer3: DB resistor may be installed due to the characteristics of the load.
Question: How do I prevent the drive from tripping on an OLT(overload) while the motor is ramping up or down?
• Answer: Verify motor rated current in bA-13 and motor overload parameter setting in Pr-20(Overload trip selection),
Pr-21(Overload trip level), and Pr-22(Overload trip time).
Question: How do I run the motor above the nominal motor speed?
• Answer: Increase the maximum frequency in dr-20. At V/f mode, maximum frequency is 400Hz and 120Hz for
sensorless mode.
Question: Does the drive create harmonics? If so, are they a problem?
• Answer: All standard drives create 5th and 7th harmonic frequencies. Occasionally, depending on the applications, there
may be issues and harmonics can cause problems such as transformer heating or interference with other communication
devices installed near the drive. To reduce interference, the installation of noise filters or line filters may be required.
Additionally, it may be helpful to adjust the carrier frequency to the minimum value in Cn-04.
1Manual Torque Boost Slightly increase the forward or reverse boost in dr-16 or dr-17
If the torque boost level is too high, a trip may occur such as IOL.
2Auto Torque Boost(ATB) Set dr-15 to 1. It is necessary to reduce the manual boost value (ex. 0~2%) in dr-16 or dr-17,
and then to adjust the values in dr-26~28.
3Starting Frequency Slightly increase the start frequency in dr-19. (ex. 0.5 →1.0 →1.5 →2.0Hz)
4User V/F Pattern When bA-07 is set to 2(User V/f), User V/f pattern can be set up according to the applications and motor
characteristics.
