As the load increases, the rotor speed of the motor will decrease. To make the rotor
speed of the motor close to the synchronous speed under rated load, slip compensation can
be enabled. When the motor speed is less than the target value, the set value of F05.11 can
be increased.
★
: In the case of F05.11=0, slip compensation is invalid. This parameter is valid only for
the asynchronous motor.
