Description of signals from axis/spindle
DB31, ...
DBX62.1 Handwheel override active
Edge evaluation: no
Signal state 1 or The function "Handwheel override in AUTOMATIC mode" is active for the programmed positioning
edge change 0 → 1 axis (FDA[AXi]). Handwheel pulses for this axis affect the programmed axis feedrate either as path
definition (FDA=0) or as velocity override (FDA > 0).
The interface signal will also be set if "Handwheel override in automatic mode" is active with a
concurrent positioning axis with FC18 ( for 840D sl).
Signal state 0 or The function "Handwheel override in AUTOMATIC mode" is not active for the programmed
edge change 1 → 0 positioning axis (or concurrent positioning axis).
An active handwheel override is not active if:

DBB64
Bit 0-2 Handwheel active (1 to 3)
Edge evaluation: no
Signal state 1 or These PLC interface signals provide feedback whether the machine axis is assigned to handwheel
edge change 0 → 1 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 to DBX4.2 (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 Neither handwheel 1, 2 nor 3 is assigned to this geometry axis.
edge change 1 → 0
