No effect.
Application
example(s)
Terminating traversing motion on account of an external signal (e.g. sensing probe).

DBX16.4 - DBX16.5 Resynchronizing spindles 2 and 1
Edge evaluation: yes Signal(s) updated: cyclic
Edge change
0 → 1
The spindle should be resynchronized, as the synchronization between the position measuring
system of the spindle and the 0 degree position has been lost.
Signal state 0 or
edge change
1 → 0
No effect.
Signal irrelevant
for ...
... Spindle modes other than the control mode.
Application
example(s)
The machine has a selector switch to changeover between a vertical and a horizontal spindle. Two
different position encoders are used (one for the vertical spindle and one for the horizontal spindle),
but only one actual value input is used on the control. When the system switches from the vertical
to the horizontal spindle, the spindle must be resynchronized.
This synchronization is triggered by the IS "re-synchronize spindle 1 or 2".
Corresponding to .... DB31, ... DBX60.4 (referenced/synchronized 1)

DBX16.3 Gear is changed over
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
When the new gear stage is engaged, the PLC user sets the interface signals:
DB31, ... DBX16.0 - DBX16.2 (actual gear stages A to C)
and
DB31, ... DBX16.3 (gear is changed over).
This signals the NCK that the correct gear stage has been successfully engaged.
The gear stage change is complete (spindle oscillation mode is deselected), the spindle accelerates
in the new gear stage to the last programmed spindle speed and the next block in the parts
program can be executed.
The interface signal:
DB31, ... DBX82.3 (change over gear)
is reset by the NCK - the PLC user then resets the interface signal:
(gear is changed over).
