Programming; Limiting The Path Jerking (Channel-Specific); General Information - Siemens SINUMERIK 840D Function Manual

12.2.12.2

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

Limiting the path jerking (channel-specific)

12.2.13.1

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.
The limitation must be activated for specific channels using setting data:
SD42512 $SC_IS_SD_MAX_PATH_JERK = TRUE
