Set S-curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop.
The following figure explains how S-curves are applied.
Figure 12.50 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.

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.
