DBX 23.0 Handwheel direction of rotation inversion for geometry axis (1, 2, 3)
Signal state 0 The handwheel direction of rotation to which geometry axis 1, 2 or 3 is assigned, is not inverted.
Application exam‐
● The handwheel direction of movement does not match the expected direction of the axis.
ple(s)
● A handwheel (HT2, HT8) has been assigned to various axes.

DBX30.0-2 Activate contour handwheel
Edge evaluation: No
Signal state 1 Request for activation of the corresponding handwheel for the "Contour handwheel / path specifica‐
tion with handwheel" function.
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 No request for activation of a handwheel.
Corresponding to ... DB21, ... DBX37.0-2 (contour handwheel active)
