4.2.13.3 Programming
Syntax
SOFTA ( Axis { Axis })
Functionality
The SOFTA part-program instruction is used to select acceleration with jerk limitation for single-axis movements
(positioning axis, reciprocating axis, etc.)
G group: -
Effective: modal
Axis :
• Value range: Axis identifier for 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 response
The axis-specific initial setting is activated via a reset:
MD32420 $MA_JOG_AND_POS_ENABLE
4.2.14 Path-jerk limitation (channel-specific)
4.2.14.1 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
