DB21, ...
DBB40, 46, 52
Bit 0-2
Handwheel active (1 to 3) for geometry axis
Edge evaluation: No
Signal state 1 or
These PLC interface signals report whether this geometry axis is assigned to handwheel 1, 2 or 3
edge change 0 → 1
or to no handwheel.
Only one handwheel can be assigned to an axis at any one time.
If several interface signals:
DB21, ... DBX12.1-3; 16.1-3; 20.1-3 (Activate handwheel)
are set, priority "Handwheel 1" before "Handwheel 2" before "Handwheel 3" applies.
If the assignment is active, the geometry axis can be traversed in JOG mode with the handwheel or
a DRF offset can be generated in AUTOMATIC or MDA modes.
Signal state 0 or
Neither handwheel 1, 2 nor 3 is assigned to this geometry axis.
edge change 1 → 0

Edge evaluation: No
The signal is the same as the travel command signal in the earlier version.
Signal state 1 or

Signal state 0 or
A travel command in the relevant axis direction has not been given or a traverse movement has
edge change 1 → 0
been completed.

Signal(s) updated: Cyclically
Signal(s) updated: Cyclically
JOG mode:
With the plus or minus traverse key.
REF mode:
With the traverse key that takes the axis to the reference point.
AUT/MDA mode:
A program block containing a coordinate value for the axis in question is executed.
JOG mode:
The travel command is reset depending on the current setting "jog or continuous mode" (DB21,
... DBB12.6-7; 16.6-7; 20.6-7).
While traversing with the handwheel.
REF mode:
When the reference point is reached.
AUT/MDA mode:
The program block has been executed (and the next block does not contain any coordinate
values for the axis in question).
Cancel by "RESET", etc.
NST DB21, ... DBX25.7 (axes disable) is active.
