◆ C3: Slip Compensation
The Slip Compensation function improves the speed accuracy of an induction motor. As loads on induction
motors increase, motor slip increases and motor speed decreases. By adjusting the output frequency in accordance
with the motor load, it compensates the slip and makes the motor speed equal to the frequency reference.
■ C3-01: Slip Compensation Gain
No.
(Hex.)

(Range)
C3-01
(020F)
RUN
Slip Compensation Gain
Sets the gain for the slip compensation function. Usually it is not necessary to change this setting.
