Signal state 1(status-
controlled)
If the new gearbox stage is engaged, then the PLC user sets the IS "Actual
gear stage A" to "...C" and the IS "Gear is changed over". This signals to 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 pro‐
grammed spindle speed and the next block in the parts program can be exe‐
cuted.
The actual gear stage is specified coded (ABC values).
There is one
parameter set for each of the 5 gear stages, which is parameter‐
ized as follows:

If the PLC user signals 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 consid‐
ered to have been successfully completed and the actual gear stage A to C is
activated.

Signal state 1 or edge
change 0 → 1
If the new gearbox stage is engaged, then the PLC user program sets the
IS
"Actual gear
stage A to C" and the IS "Gear stage 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 NCK
resets the IS "Change gear stage" and then the PLC user program resets
the IS "Gear stage is changed over".

No effect
