C2: S-Curve Characteristics
Use C2 parameters to configure S-curve operation.
C2-01
<15>
S-Curve Characteristic at
Accel Start
The S-curve can be controlled in the four points shown
below.
S-curve is used to further soften the starting and
stopping ramp. The longer the S-curve time, the softer
the starting and stopping ramp.
