Functions
2.12 Jerk limitation with single-axis interpolation (SOFTA) (axis-specific)
2.12.2 Activation
2.12.2.1 Parameterization
Function
The function's initial setting and the maximum values are parameterized for specific axes
using machine data:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE
(initial setting of axial jerk limitation)
MD32430 $MA_JOG_AND_POS_MAX_JERK (maximum axis jerk)
2.12.3 Programming
Syntax
SOFTA (
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
