Maximum axial jerk for JOG motions
For JOG mode, a JOG-specific maximum jerk value can be configured for each machine axis
(see Section "Acceleration and jerk for JOG motions (Page 282)").
5.2.12.2

Programming

Syntax
SOFTA (
Functionality
The SOFTA part-program command is used to select acceleration with jerk limitation for single-
axis movements (positioning axis, reciprocating axis, etc.)
G group: -
Effectiveness: Modal
Axis :
● Value range: Axis name of the channel axes
Axis-specific initial setting
Acceleration with jerk limitation can be set as the axis-specific initial setting for single-axis
movements:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE = TRUE
Reset behavior
The axis-specific initial setting is activated via a reset:
MD32420 $MA_JOG_AND_POS_ENABLE

Path-jerk limitation (channel-specific)

5.2.13.1

General Information

Overview
To enable a flexible response to the machining situations concerned, setting data can be used
to limit the path jerk calculated during preprocessing for specific channels:
SD42510 $SC_SD_MAX_PATH_JERK (maximum path jerk)
The value specified in the setting data is only taken into account in the channel if it is smaller
than the path jerk calculated during preprocessing.
