Machine data
2.2 General machine data
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 tra-
verse 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).
Related to:
NC/PLC interface signal DB3200 DBX5 (Rapid traverse override A-H)
MD12050 $MN_OVR_FACTOR_RAPID_TRA[n]
(Evaluation of the rapid traverse override switch)
Description: Evaluation of the rapid traverse override switch with gray-coded interface.
Not relevant with:
MD12040 $MN_OVR_RAPID_IS_GRAY_CODE = 0
Related to:
NC/PLC interface signal DB3200 DBX5 (Rapid traverse override A-H)
Description: This machine data is used to adapt the spindle speed override switch to the
interface coding of the PLC interface.
1: The 5 low-order bits of the "spindle speed override" PLC interface sig-
nal 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 MD12070 $MN_OVR_FACTOR_SPIND_ SPEED [n].
0: The spindle speed override byte of the PLC interface is interpreted as a
binary representation of the override value in percent (limit 200 percent).
Related to:
NC/PLC interface signal DB380x DBX2003 (Spindle speed override)
MD12070 $MN_OVR_FACTOR_SPIND_SPEED[n]
