Slip Compensation
Parameter # 55
Parameter Name
Slip compensation
Factory Setting
d000.0
Units
0.1%
Parameter value
d000.0 - d010.0%
 This parameter can be programmed while the drive is running.
 This parameter is used to compensate for the nominal slip within a range of 0.0 -
10.0%. 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 Pr.55.
 Example: If Pr. 04 is set at 60Hz and Pr. 55 is set at 10%, the drive will increase the
output frequency up to 6% under full load conditions to compensate for slip.
