Jerk limitation with path interpolation (SOFT) (channel-specific)

As far as the functionality described in the rest of this document is concerned, constant acceleration, i.e.,

acceleration with jerk limitation (jerk = infinite value), is the assumed acceleration profile. In the case of

acceleration with jerk limitation, linear interpolation is applied in respect of acceleration from 0 to the maximum

Minimal load on the machine's mechanical components and low risk of high-frequency and difficult-to-control

mechanical vibrations thanks to constant excessive acceleration.

Disadvantages

Longer machining times compared with stepped acceleration profile when the same maximum velocity and

acceleration values are used.
