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