C2-01 to C2-04: S-Curve Characters
C2-01 through C2-04 set separate S-curves for each section of the acceleration or
deceleration.
Figure 1.26 explains how S-curves are applied.
Figure 1.26
Figure 1.26 S-Curve Timing Diagram - FWD/REV Operation
Setting the S-curve will increase the acceleration and deceleration times.
Actual accel time = accel time s (C2-01 + C2-02)/2
Actual decel time = decel time s (C2-03 + C2-04)/2

C3: Slip Compensation
The Slip Compensation function prevents motor speed loss due to an increase in load.
Note: Before making changes to the Slip Compensation parameters, make sure the motor parameters
and V/f pattern are set properly or perform Auto-Tuning.
■
C3-01: Slip Compensation Gain
This parameter sets the gain for the motor slip compensation function. Although this
parameter rarely needs to be changed, adjustments might be needed under the following
situations:
No. Parameter Name Setting Range Default
C2-01 S-Curve Characteristic at Accel Start
0.00 to 10.00 s
