• If the values for acceleration and deceleration times are extremely low, the rise times and set-

tling times of the drive become already noticeable and superimpose the desired speed profile.

Although the acceleration and deceleration times can be physically provided by the drive, they

are not feasible in a control-oriented manner, so that delays result.

[8-2] Drive behaviour for highly dynamic motion profiles

• These effects can occur in the case of highly dynamic clocked drives, like for example cam appli-

cations, cross cutters, handling devices, robots, packaging machines.
