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

B2: Acceleration
5.2 Functions
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.

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

5.2.12.1

Parameterization

Initial setting for axial jerk limitation
Acceleration with jerk limitation can be set as the axial initial setting:
MD32420 $MA_JOG_AND_POS_JERK_ENABLE== TRUE
Maximum axial jerk for positioning axis motions
When traversing positioning axes with active jerk limitation, the value from one of the following
machine data takes effect as maximum axial jerk:
● MD32430 $MA_JOG_AND_POS_MAX_JERK (maximum axial jerk for positioning axis
motions)
● MD32431 $MA_MAX_AX_JERK [0] (maximum axial jerk for path motions in the dynamic
response mode DYNNORM)
● MD32431 $MA_MAX_AX_JERK [1] (maximum axial jerk for path motions in the 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>
262
Meaning
The following is effective as maximum axial 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]
