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.

Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge

The spindle should be resynchronized, as the synchronization between the
position measuring system of the spindle and the 0° 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 The machine has a selector switch for a vertical and horizontal spindle. Two
different
position measuring
encoders are required, but only one actual value
input is used at 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".
