Handwheel assignment for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Request for activation of the appropriate geometry axis handwheel.
The interface can be interpreted either bit or binary-coded. The selection is defined using machine
data:
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"
Number of the assigned handwheel Bit 2 Bit 1 Bit 0
