B2: Acceleration
4.2 Functions
Basic Functions

235
Functionality
The SOFT part-program instruction is used to select the acceleration profile with jerk limitation for the traversing
operations of geometry axes in the channel.
G group: 21
Effective: Modal
Reset response
The channel-specific initial setting is activated via a reset:
MD20150 $MC_GCODE_RESET_VALUES[20]
Boundary conditions
If the acceleration mode is changed in a part program during machining (BRISK ↔ SOFT), a block change is
performed at the point of transition with an exact stop at the end of the block, even in continuous-path mode.
4.2.13 Jerk limitation with single-axis interpolation (SOFTA) (axis-specific)
4.2.13.1 General Information
Overview
The maximum jerk value can be set for each specific machine axis for single-axis movements (setup modes e.g.
JOG, JOG/INC, positioning axis, reciprocating axis, etc.):
MD32430 $MA_JOG_AND_POS_MAX_JERK (maximum axis jerk)
Initial setting
Acceleration with jerk limitation can be set as the axial initial setting:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE
(initial setting of axial jerk limitation)
4.2.13.2 Parameterization
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)
