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.
