Slip Compensation
Settings 0.00 to 10.00 Factory Setting: 0.00
★
This parameter can be used to compensate motor slip. Although no linear, it typically adds 6Hz for a
setting of 10 if Pr.03=60 Hz. When the output current of the AC drive is greater than the motor
no-load current (Pr.53), the AC drive will adjust its output frequency according to this parameter.
