It is enabled only for V/F control. Setting this parameter can compensate the
slip in the V/F control mode due to load and reduce the change of rotation
speed of the motor following the load change. In general, 100% corresponds
to the rated slip of the motor with rated load. Slip coefficient adjustment can
refer to the following principles: When the load is rated load and the slip
compensation coefficient is set to 100%, the rotation speed of the motor in
the driver is close to the reference speed.
