Set Values
·The default setting does not need any changes in normal operation.
·Change the default setting in the following cases.
The wiring distance between the Inverter and motor is long:
Set the gain to a larger value.
The capacity of the motor is lower than the maximum applicable motor capacity of
the Inverter:
Set the gain to a larger value.
The motor vibrates:
Set the gain to a smaller value.
·The torque compensation gain must be adjusted so that the output current at low
speed will not exceed 50% of the rated output current of the Inverter, otherwise the
Inverter may be damaged.
