Jerk Limitation With Path Interpolation (Soft) (Channel-Specific); General Information - Siemens SINUMERIK 840D Function Manual

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

12.2.11.1

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.
