Changing the characteristic of the ramp function generator
You can select two different characteristics for the ramp function generator of the speed
setpoint via C0134:
ƒ
A linear characteristic for all acceleration processes that are required for a constant
acceleration.
ƒ
S−shaped characteristic for all acceleration processes that require a jerk−free
acceleration.
