DB21, ...
DBX320.0-2,
DBX324.0-2, Activate handwheel for orientation axis (1, 2, 3)
DBX328.0-2
Edge evaluation: No
Signal state 1 Request for activation of the corresponding handwheel 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 No request for activation of a handwheel.

DBX323.0,
DBX327.0, Handwheel direction of rotation inversion for orientation axis (1, 2, 3)
DBX331.0
Edge evaluation: No
Signal state 1 Request for inversion of the handwheel direction of rotation assigned to orientation axis 1, 2 or 3.
Note
It is only permissible to change the inversion signal at standstill.
Signal state 0 Inversion has not been requested.
Application exam‐
● The handwheel direction of rotation should match the axis direction of motion.
ple(s)
● A handwheel is assigned to several axes with different orientations.
