Bit 0-5 Machine function INC1, INC10, INC100, INC1000, INC10000, INCvar
Edge evaluation: No
Signal state 1 Request to activate a machine function for incremental traversing of the axis:
● Bit 0: INC1
● Bit 1: INC10
● Bit 2: INC100
● Bit 3: INC1000
● Bit 4: INC10000
● Bit 5: INCvar
One increment corresponds to actuating the traversing key or a detent position of the handwheel.
The size of an increment is defined in the following system data:
● INC1 to INC10000:
● INCvar:
The feedback signal indicating that the machine function has been activated is realized via:
DB31, ... DBB65 (machine function INC1, ...)
Notice
If several bits are simultaneously set, then no machine function is active in the control.
Signal state 0 The corresponding machine function is not requested.
If the axis is presently traversing an increment, motion is canceled when the machine function is
either selected or changed over.
Corresponding to ... DB31, ... DBB65 (machine function INC1, ...)

DBX5.6 Continuous machine function
Edge evaluation: No
Signal state 1 The machine axis can be continuously traversed with the traversing keys "plus" and "minus" in the
JOG mode.
Signal state 0 The machine function "Continuous jogging" is not selected.
Corresponding to ... DB31, ... DBB65 (active machine function INC1, ..., continuous)
DB31, ... DBB5 (machine function INC1, ..., INC10000)

DBX7.0 Invert handwheel direction of rotation (machine axes)
Edge evaluation: No
Signal state 1 The direction of rotation of the handwheel, which is assigned to the machine axes, is inverted.
It is only permissible to change the inversion signal at standstill.
Signal state 0 The handwheel direction of rotation is not inverted.
