DBX37.0 Handwheel 1 active as contour handwheel
DBX37.1 Handwheel 2 active as contour handwheel
DBX37.2 Handwheel 3 active as contour handwheel
Edge evaluation: No
Description These signals show which handwheel is selected as contour handwheel:
Signal = 1
Signal = 0
Special cases, The signal is kept beyond an NC Reset.

DBX39.5 Handwheel direction of rotation inversion active for contour handwheel
Edge evaluation: No
Description This signal indicates whether the direction of rotation was inverted for the contour handwheel:

Signals to axis/spindle (DB31, ...)

Description of signals to axis/spindle
DB31, ...
DBB4
Bit 0-2 Activate handwheel (1 to 3)
Edge evaluation: No
Signal state 1 or edge This PLC interface signal defines whether this machine axis is assigned to handwheel 1, 2, 3 or no
change 0 → 1 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 Neither handwheel 1, 2 nor 3 is assigned to this geometry axis.
change 1 → 0
