Traversing command plus and minus for geometry axis (1, 2, 3)
Application
example(s)
Releasing the axis clamp when the traversing command is identified.
Note
For axes on which the clamping is not released until a drive command is detected, continuous-path
mode (
G64) is not possible.

Active machine functions for geometry axis (1, 2, 3)
INC1, INC10, INC100, INC1000, INC10000, INCvar, continuous
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 The corresponding machine function is active.
• Bit 0 = 1 INC
• Bit 1 = 10 INC
• Bit 2 = 100 INC
• Bit 3 = 1000 INC
• Bit 4 = 10000 INC
• Bit 5 = Var. INC
• Bit 6 = continuous
The reaction to actuation of the traversing key or rotation of the handwheel varies, depending on
which machine function is active.
Signal state 0 The machine function in question is not active.

DBX43.0, 49.0, 55.0 Handwheel direction of rotation inversion active for geometry axis (1, 2, 3)
Edge evaluation: No Signal(s) updated: Cyclically
Signal state 1 The inversion of the handwheel direction of rotation is active for the geometry axis.
Signal state 0 The inversion of the handwheel direction of rotation is not active for the geometry axis.
Corresponding to ... DB31, ... DBX15.0, DBX19.0, DBX23.0.(invert handwheel direction of rotation for geometry axis)
