S-curve ramp-function generator
You can also use the S-curve ramp-function generator by setting p1115 to 1. The S-curve
ramp-function generator is realized with the following parameters:
● the acceleration (p1120) and deceleration (p1121) ramps
● the initial (p1130) and final (p1131) rounding-off times
You can see the properties of the S-curve ramp-function generator from the diagram below:
