Figure 11.51 S-Curve Timing Diagram - Forward/Reverse Operation
Note:
• If STPo [Motor Step-Out Detected] occurs when starting a PM motor, try increasing the value set to C2-01.
• Setting the S-curve will increase the acceleration and deceleration times.
■ C2-01: S-Curve Time @ Start of Accel

◆ 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.)
Name Description
Default
(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.
