Traversing key disable for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 A traversing request using the "Plus" and "Minus" traversing keys is ignored for the geometry axis.
If the traversing key disable is activated while traversing, then traversing is canceled.
Signal state 0 The plus and minus traversing keys are enabled.
Application
example(s)
It is thus possible, depending on the operating mode, to disable manual traversing of the geometry
axis in JOG mode with the traversing keys from the PLC user program.

Rapid traverse override for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 Moves the axis due to a traversing request:
• DB21, ... DBX12.7 == 1 (traversing key plus)
• DB21, ... DBX12.6 == 1 (traversing key minus)
when the interface signal is set, the geometry axis is moved with rapid traverse.
The rapid traverse feedrate is defined in machine data:
MD32010 $MA_JOG_VELO_RAPID (conventional rapid traverse)
The rapid traverse override is effective in JOG mode for:
• Continuous travel
• Incremental travel (INC1, INC10, ...)
The rapid traverse velocity can be influenced using the rapid traverse override switch.
Signal state 0 The geometry axis traverses with the defined JOG velocity:
SD41110 $SN_JOG_SET_VELO (axis velocity with JOG)
or
MD32020 $MA_JOG_VELO (conventional axis velocity).
