The slip compensation function calculates the motor torque according to
the output current, and sets gain to compensate for output frequency.
This function is used to improve speed accuracy when operating with a
load.

Setting 0.0 to 20.0 (Hz)
range
Note The default setting varies with the capacity of the Inverter model.
Set Values
Set the rated slip value of the motor in use.
This parameter is used as a slip compensation constant.

Note The default setting varies with the capacity of the Inverter model.
Set Values
Set the motor current with no load in percentage based on the rated motor current as
