DBX4.4 Traversing key lock
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
The traverse keys plus and minus have no effect on the machine axes in question. It is thus not
possible to traverse the machine axis in JOG with the traverse keys on the machine control panel.
If the traverse key disable is activated during a traverse movement, the machine axis is stopped.
Signal state 0 or
edge change 1 → 0
The plus and minus traverse keys are enabled.
Application
example(s)
It is thus possible, depending on the operating mode, to disable manual traverse of the machine
axis in JOG mode with the traverse keys from the PLC user program.

DBX4.5 Rapid traverse override
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
If together with interface signal:
DB31, ... DBX4.0, 4.1, 4.2 (traverse key plus or traverse key minus)
the PLC interface signal:
DB31, ... DBX4.5 (Rapid traverse override)
is sent, then the corresponding machine axis is operating 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 the JOG mode for the following versions:
• Continuous jogging
• Incremental jogging
If rapid traverse override is active, the velocity can be modified with the rapid traverse override
switch.
Signal state 0 or
edge change 1 → 0
The machine axis traverses with the defined JOG velocity:
SD41110 $SN_JOG_SET_VELO (Axis velocity with JOG)
or
MD32020 $MA_JOG_VELO (Conventional axis velocity).
