Description: Evaluation of the axis velocity override switch with gray-coded interface.
Not relevant with:
MD12000 $MN_OVR_AX_IS_GRAY_CODE = 0
Related to:
NC/PLC interface signal DB380x DBX0 (Feed override A-H), (axis-specific)

- - TRUE 0 - 1/1
Description: This machine data is used to adapt the path feed override switch to the interface
coding of the PLC interface.
1: The 5 low-order bits of the NC/PLC interface signal DB380x DBX0 (Feed override
A-H) are interpreted as a Gray code. The value which is read corresponds to a switch
setting. It is used as an index for selecting the correct override factor from the
table of MD12030 $MN_OVR_FACTOR_FEEDRATE [n].
0: The feed override byte of the PLC interface is interpreted as a binary
representation of the override value in percent (limit 200 percent).

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.

- - TRUE 0 - 1/1
Description: This machine data is used to adapt the rapid traverse override switch to the interface
coding of the PLC interface.
1: The 5 low-order bits of the PLC interface signal DB3200 DBX5 (Rapid traverse
override A-H) are interpreted as a Gray code. The value which is read corresponds to
a switch setting.
It is used as an index for selecting the correct override factor from the table of
MD12050 $MN_OVR_FACTOR_RAPID_TRA[n].
0: The rapid traverse override byte of the PLC interface is interpreted as a binary
representation of the override value in percent (limit 200 percent).
