n023 : S-Curve Selection
Factory setting: 0
Range: 0 to 3
Setting of this parameter
determines the S-curve
(starting) characteristics
of the acceleration ramp.
0 = S-curve disabled
1 = S-curve
of 0.2 seconds
2 = S-curve time
of 0.5 seconds
3 = S-curve time
of 1.0 seconds
NOTE: Actual accel time = Set accel time + (2
*
S-curve selection)
Actual decel time = Set decel time + (2
*
S-curve selection)
The following figure shows FWD/REV switching and acceleration & deceleration to a stop with
S-curve active.
