The change in motor torque will affect motor slip
and result in speed change. Through slip
compensation, the output frequency can be
adjusted according to motor load torque, so as to
reduce speed change caused by load change.
See Fig. 5-17.

Fig. 5-17 Auto Slip Compensation
Electromotion state: Increase the gain of slip
compensation gradually when the actual speed is
lower than the reference speed (F3.07)
Power generation state: Increase the gain of slip
compensation gradually when the actual speed is
higher than the reference speed (F3.07).

rated slip (FH.08).
Note:
The value of automatically compensated slip is
dependent on the motor’s rated slip, therefore the
motor’s rated slip must be set correctly (FH.08)

:
1. To get the best control effect, the ratio of carrier
wave frequency to the max. operating frequency of
the drive should be lower than 36.
2. The displayed current might have error when the
carrier frequency is lower
