Handwheel active for orientation axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Feedback signal indicating which handwheel is active for the orientation axis.
The interface can be interpreted either bit or binary-coded. The specification is performed via:
MD11324 $MN_HANDWH_VDI_REPRESENTATION
Bit-coded: Maximum of three handwheels
Note
At any one time, the axis can only be assigned to one handwheel. If several interface signals are
set simultaneously, then the following priority applies: "Handwheel 1" before "handwheel 2" before
"handwheel 3"

Plus and minus traversing request for orientation axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
The signal is the same as the previous traversing command signal.
Signal state 1
• JOG mode:
With the plus or minus traversing key.
• REF mode:
With the traversing key that takes the axis to the reference point.
• AUTOMATIC/MDI mode:
A program block containing a coordinate value for the axis in question is executed.
