Siemens SINUMERIK 840Di Function Manual page 240

Detailed Description
2.15 Jerk with programmed rapid traverse (G00) (axis-specific)
Functionality
The path jerk for real-time events is set via the channel-specific system variables.
Jerk value
• Value range: Path jerk ≥ 0
• Unit: m/s
Application:
• Part program
• Static synchronized action
Reset response
The function is deactivated on reset.
Supplementary conditions
Programming $AC_PATHJERK in the part program automatically triggers a preprocessing
stop with REORG (STOPRE).

2.15.1 Detailed description
2.15.1.1 General information
Key statement
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.
