This parameter is set to auto slip compensation gain.
Rotor speed of the motor (output frequency of AC drive) can’t synchronize due to induction motor characteristic. The difference between synchronization speed and rotor speed is called slip frequency. Slip frequency is in direct proportion with output torque and output current. Therefore, slip compensation could make rotor speed and master frequency command the same according output current (lo).
The equation of slip compensation is
Output frequency after compensation is limited by
When PID feedback control, slip compensation function will be disabled.
Unsuitable setting value may cause over compensation.
