5.7 Slip Compensation Operation
Slip refers to the variation between the setting frequency (synchronous speed) and motor
rotation speed. As the load increases there can be variations between the setting frequency
and motor rotation speed. Slip compensation is used for loads that require compensation of
these speed variations.
