Jerk Limitation With Single-Axis Interpolation (Softa) (Axis-Specific); Parameterization - Siemens SINUMERIK 840D Function Manual

B2: Acceleration and jerk
12.2 Functions
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.

Jerk limitation with single-axis interpolation (SOFTA) (axis-specific)

12.2.12.1

Parameterization

Basic setting of axis-specific jerk limitation
Acceleration with jerk limitation can be set as the axis-specific initial setting:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE== TRUE
Maximum axis-specific jerk for positioning axis movements
When traversing positioning axes with active jerk limitation, the value from one of the following
machine data takes effect as the maximum axis-specific jerk:
● MD32430 $MA_JOG_AND_POS_MAX_JERK (maximum axis-specific jerk)
● MD32431 $MA_MAX_AX_JERK [0] (maximum axis-specific jerk for path motions in the
dynamic response mode DYNNORM)
● MD32431 $MA_MAX_AX_JERK [1] (maximum axis-specific jerk for path motions in
dynamic response mode DYNPOS)
The machine data to be used is determined by the set positioning axis dynamic response mode:
MD18960 $MN_POS_DYN_MODE = <mode>
<mode>
Maximum axial jerk for JOG motions
See Chapter "Acceleration and jerk for JOG motions (Page 388)".

Meaning
The following applies as the maximum axis-specific jerk for positioning axis motions:
0 MD32430 $MA_JOG_AND_POS_MAX_JERK
With active G75 (fixed-point approach): MD32431 $MA_MAX_AX_JERK[ 0 ]
1 MD32431 $MA_MAX_AX_JERK[ 1 ]
