Handwheel 1 active as contour handwheel
Handwheel 2 active as contour handwheel
Handwheel 3 active as contour handwheel
Edge evaluation: No Signal(s) updated: Cyclic
These signals show which handwheel is selected as contour handwheel:
Signal = 1 Handwheel x is selected as contour handwheel.
Description
Signal = 0 Handwheel x is deselected as contour handwheel.
Special cases,
errors, ...
The signal is kept beyond an NC Reset.

DBX39.5 Handwheel direction of rotation inversion active for contour handwheel
Edge evaluation: No Signal(s) updated: Cyclic
This signal indicates whether the direction of rotation was inverted for the contour handwheel:
Signal = 1 The direction of rotation of the contour handwheel is inverted.
Description
Signal = 0 The direction of rotation of the contour handwheel is not inverted.
Corresponding to ... DB31, ... DBX31.5 (invert handwheel direction of rotation for the contour handwheel)

Signal state 1 or
edge change 0 → 1
This PLC interface signal defines whether this machine axis is assigned to handwheel 1, 2, 3 or no
handwheel.
Only one handwheel can be assigned to an axis at any one time.
If several interface signals:
DB31, ... DBX4.0, 4.1, 4.2 (Activate handwheel)
are set, priority "Handwheel 1" before "Handwheel 2" before "Handwheel 3" applies.
If the assignment is active, the machine axis can be traversed with the handwheel in JOG mode or
a DRF offset can be generated in AUTOMATIC or MDA mode.
Signal state 0 or
edge change 1 → 0
Neither handwheel 1, 2 nor 3 is assigned to this geometry axis.
Application
example(s)
The PLC user program can use this interface signal to disable the influence of turning the
handwheel on the axis.
Corresponding to ... DB31, ... DBX64.0 to DBX64.2 (Handwheel active)
