19.3 Manual and Handwheel Travel (H1)
DB21, ...
DBX332.0-2,
DBX336.0-2, Handwheel active for orientation axis (1, 2, 3)
DBX340.0-2
Edge evaluation: No
Signal state 1 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"
Binary-coded: Maximum of six handwheels
Signal state 0 A handwheel is not active for the orientation axis.
Corresponding to ... DB21, ... DBX332.0-2 ff (activate handwheel)
DB21, ...
DBX332.4-5,
DBX336.4-5, Plus and minus traversing request for orientation axis (1, 2, 3)
DBX340.4-5
Edge evaluation: No
The signal is the same as the previous traversing command signal.

Signal(s) updated: Cyclically
Number of the assigned handwheel
Number of the assigned handwheel
Signal(s) updated: Cyclically
With the plus or minus traversing key.
With the traversing key that takes the axis to the reference point.
A program block containing a coordinate value for the axis in question is executed.
