It can compensate the rotational speed slip of the asynchronous motor when the load of the
motor increases, stabilizing the motor speed in case of load change.
If this parameter is set to 100%, it indicates that the compensation when the motor bears
rated load is the rated motor slip.
When the motor bears the rated load and this parameter is set to 100%, the rotational speed
of the motor is close to the set speed. Modify this parameter based on such a principle.
Before performing automatic torque boost or slip compensation, carry out motor auto-tuning
to guarantee the control effect. Follow the precautions:
 When this parameter is set to a large value, the motor may oscillate. In this case,
decrease the value of this parameter.
 Do not use the automatic torque boost and slip compensation functions simultaneously.

Set these parameters based on the motor parameters. If these parameters are set
incorrectly, the control performance will be affected. If you are sure about the values,
perform motor auto-tuning, or contact the manufacturer of the motor.

Set this parameter to 0 if the motor has no oscillation. Increase the value properly only
when the motor has obvious oscillation. The larger the value is, the better the oscillation
suppression result will be.
When the oscillation suppression function is enabled, the rated motor current and no-
load current must be correct. Otherwise, the V/F oscillation suppression effect will not be
satisfactory.
