CHAPTER 3 - VARIOUS FUNCTION SETTING & DESCRIPTION
3.1 Function Setting
3.1.1

Basic function parameter setting

It is the basic function setting. All settings are factory defaults unless users make change. It is recommended to use
factory setting value unless the parameter change is necessary.

1) Common parameter setting

The following table shows common parameter setting that should be checked before use but making change does not
affect inverter control type.
Parameter Name
Motor Selection
Motor parameters
Drive Mode
Frequency or
Torque Mode
Accel/Decel time
setting

2) V/f control

FU2-39 [Control mode] is set to 0 (V/F) as factory setting. Operation via V/F control can be performed after common
parameter settings are done and the followings are set.
Parameter Name
Starting freq.

Code
Selects motor and voltage rating suitable to the desired
FU2-30
inverter.
Basic parameter value setting when selecting the motor
rating.
☞ Note: If there is any discrepancy between parameter
FU2-31 ~ 36
preset value and the actual motor parameter value,
change the parameter value according to the actual
motor.
DRV-3 Operation via Keypad, Fx/Rx-1, Fx/Rx-2 setting
Frequency/Torque setting parameter
DRV-4 It automatically changes to torque mode when FU2 39-
[Control mode] is set to Sensorless_T, Vector_TRQ.
DRV-1, DRV-2 Accel/Decel time setting
Code
FU1-22 Set frequency to start the motor.
Manual or Auto torque boost settable in this parameter
FU1-26
If FU1-26 [torque boost] is set to manual, user sets the
FU1-27, FU1-28
desired value and the direction in code FU1-27 and 28.
