4.2.12 Jerk limitation with path interpolation (SOFT) (channel-specific)
4.2.12.1 General Information
Overview
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
value.
Advantages
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.
