Machine data
3.2 General machine data
12030 OVR_FACTOR_FEEDRATE
- Evaluation of path feedrate override switch
-
- 31
Description:
Evaluation of the feedrate override switch with gray-coded interface.
Special function of the 31st value for the velocity control:
The setting of the 31st override value defines the dynamic reserves which take the
velocity control to be an excessive increase in the path feed. The setting should
correspond to the highest override factor actually used.
Not relevant with:
MD12020 $MN_OVR_FEED_IS_GRAY_CODE = 0
Related to:
NC/PLC interface signal DB380x DBX0 (Feed override A-H)
12040 OVR_RAPID_IS_GRAY_CODE
- Rapid traverse override switch Gray-coded

Description:
This machine data is used to adapt the rapid traverse override switch to the interface
coding of the PLC interface.

a switch setting.
It is used as an index for selecting the correct override factor from the table of
