4.4.4. 3-4* Accel/Decel 1
A linear ramp is characterized by ramping up at a constant speed until the desired motor speed has been reached. Some overshoot may be experienced when
reaching speed, which may cause speed jerks for a short while before stabilizing.
An S-ramp accelerates more smoothly thus compensating for jerks when the speed is reached.
See the below figure for a comparison of the two ramp types.
Accel/Decel Time:
Acceleration time from 0 to nominal motor frequency (par. 1-23).
Ramp down: Deceleration time from nominal motor frequency (par. 1-23) to 0.
