Jerk With Programmed Rapid Traverse (G00) (Axis-Specific); General Information; Parameterization - Siemens SINUMERIK 840D sl Function Manual

Boundary conditions
Programming $AC_PATHJERK in the part program automatically triggers a preprocessing
stop with REORG (STOPRE).

Jerk with programmed rapid traverse (G00) (axis-specific)

5.2.15.1

General Information

Overview
Frequently, the maximum jerk for the machine axes involved in the machining process must
be set lower than the machine's performance capability officially allows because of the
supplementary conditions associated with the specific process concerned.
For time-optimized traversing of the machine axes with programmed rapid traverse (part-
program instruction G00), a specific maximum value can be programmed for the axis-specific
jerk.
JOG setup mode
This function does not affect jerk in respect of a rapid traverse override in JOG setup mode.
5.2.15.2

Parameterization

The maximum value for axis-specific jerk with programmed rapid traverse is parameterized
(G00) using the axis-specific machine data:
MD32434 $MA_G00_ACCEL_FACTOR
(scaling of the acceleration limitation with G00)
This is used to generate the maximum value for axis-specific jerk with programmed rapid
traverse (G00) that is taken into account by the path planning component during preprocessing:
Jerk[axis] =
MD32431 $MA_MAX_AX_JERK * MD32435 $MA_G00_JERK_FACTOR
