Axis replacement
Synchronization with preprocessing stop
On the transition of an axis from "PLC axis," "neutral axis," or "axis in another channel" status
to "channel axis" status, synchronization with preprocessing stop and synchronization in the
fetching channel are performed. This involves:
● Axis: Accept the actual axis position
● Spindle: Accepting the current speed and current gearbox stage
