If, together with the "Traversing key plus" or "Traversing key minus" the PLC
interface signal "Rapid traverse override" is issued, then the geometry axis
that is addressed traverses with the rapid traverse - intended for JOG - of
the associated machine axis (e.g.: X → X1).
This rapid traverse velocity is defined using MD32010 JOG_VELO_RAPID.
The rapid traverse override is effective in the JOG mode for the following
versions:
● for continuous travel
● for incremental travel
If rapid traverse override is active, the velocity can be modified with the rapid
traverse override switch.
The geometry axis traverses with the specified JOG velocity (SD41110
JOG_SET_VELO or MD32020 JOG_VELO).
● AUTOMATIC and MDI modes
● Reference point approach (JOG mode)

The selected axis can be traversed in both directions in JOG mode using
the plus and minus traversing keys.
Incremental travel
With signal state 1 the axis starts to traverse the set increment. If the signal
changes to the 0 state before the increment is traversed, the traversing
movement is interrupted. With a new signal state 1, the traversing motion is
continued.
Until the increment has been completely traversed, the axis traversing mo‐
tion can be stopped and continued a multiple number of times as described
above.
Continuous traversing
If an INC dimension has not been selected, but "continuous", then the axis
traverses as long as the traversing key is kept pressed.
If both traverse signals (plus and minus) are set at the same time, no move‐
ment occurs, or any current movement is aborted!
The effect of the traversing keys can be disabled for every axis individually
using the PLC interface signal "Traversing key disable".
Notice:
In contrast to machine axes, for geometry axes, only one geometry axis can
be traversed at any one time using the traversing keys. Alarm 20062 is output
if an attempt is made to traverse more than one axis using the traversing
keys.
