DB21, ...
DBX40.0-2,
DBX46.0-2, Handwheel active for geometry axis (1, 2, 3)
DBX52.0-2
Edge evaluation: No
Signal state 1 Feedback signal indicating which handwheel is active for the geometry 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 None is active for the geometry axis.
Corresponding to ... DB21, ... DBX12.0-2 ff (activate handwheel)

DBX40.4-5,
DBX46.4-5,
DBX52.4-5 Plus or minus traversing request for geometry axis (1, 2, 3)
Edge evaluation: No
Signal state 1 A traversing request is available for the geometry axis for the corresponding traversing direction.
● Bit 4 = minus traversing request
● Bit 5 = plus traversing request
Operating modes:
● JOG mode:
● REF mode:
● AUTOMATIC/MDI modes:
