• Although a deceleration dwell operation is carried out whenever stop commands are entered
and the deceleration dwell frequency is passed through, it does not work during a deceleration
operation by a simple frequency change (which is not deceleration due to a stop operation), or
during external brake control applications.

8.7 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.*
*If DRV-09 is set to Sensorless, Vector, or V/F PG, the variation (slip) is automatically compensated.
