Request for incremental machine function for geometry axis (1, 2, 3)
Edge evaluation: No
Signal state 1 Request for a machine function for incremental traversing of the geometry axis in JOG mode:
● Bit 0 = INC1
● Bit 1 = INC10
● Bit 2 = INC100
● Bit 3 = INC1000
● Bit 4 = INC10000
● Bit 5 = INCvar
An increment corresponds to an actuation of one of the "plus" and "minus" traversing keys, or a detent
position of the active handwheel. Specification of the increment sizes via:
● INC1 to INC10000:
● INCvar:
Note
If several requests are set simultaneously, no machine function becomes active.
Signal state 0 No machine function is requested.
If a geometry axis is currently being traversed via a machine function, the movement is aborted
through deselection or change of the machine function.
Corresponding to ... DB21, ... DBB41 ff (active machine function INC1,...) for geometry axes

DBX21.6 Request for continuous machine function for geometry axis (1, 2, 3)
Edge evaluation: No
Signal state 1 The machine function for continuous traversing of the geometry axis in JOG mode with the traversing
keys "Plus" and "Minus" is requested.
Signal state 0 Machine function "Continuous traversing" is not requested.
Corresponding to ... DB21, ... DBB41.6 ff (active continuous machine function)

DBX 23.0 Handwheel direction of rotation inversion for geometry axis (1, 2, 3)
Edge evaluation: No
Signal state 1 Request to invert the handwheel direction of rotation.
It is only permissible to change the interface signal when the geometry axis is at a standstill.
