Control functions
7.5 Speed control (S)
The maximum speed p1082 is used as the reference value for calculating the ramp-up and
ramp-down times.
You can see the properties of the ramp-function generator from the diagram below:
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 acceleration (p1120) and deceleration (p1121) ramps
● the initial (p1130) and final (p1131) rounding-off times
