If the PLC user reports back to the NCK with a different actual gear stage than issued by the NCK
as the setpoint gear stage, the gear change is still considered to have been successfully completed
and the actual gear stage A to C is activated.
Corresponding to .... DB31, ... DBX16.2 - DBX16.0 (actual gear stage A to C)
DB31, ... DBX82.2 - DBX82.0 (setpoint gear stage A to C)

DB31, ... DBX18.5 (oscillation speed)
DB31, ...
DBX16.0 - DBX16.2
Actual gear stage A to C
Edge evaluation: yes Signal(s) updated: cyclic
Signal state 1
(status-controlled)
If the new gear stage is engaged, the PLC user program sets the interface signals:
DB31, ... DBX16.2 - DBX16.0 (actual gear stage 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 change is considered to have been completed (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 actual gear stage is output in coded format.
For each of the 5 gear stages, there is one set of parameters assigned as follows:

Special cases,
errors, ......
If the PLC user program signals a different actual gear stage back to the NCK than that issued by
the NCK as the setpoint gear stage, the gear stage change is still considered as having been
successfully completed and the actual gear stage A to C is activated.
