C3: Slip Compensation - YASKAWA GA700 Technical Manual

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.

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.
