• Synchronous:
The "Flying saw" never moves faster than the material. For this
purpose an offset is calculated online and the "Flying saw" therefore
starts before the cutting position reaches the saw. The advantage
this mode offers for synchronisation is primarily that maximum
process speeds for the synchronous axis cannot be exceeded. This
situation could be the case when the master speed for the material
to be machined is already very high and the synchronous axis would
hit the maximum speed limit trying to catch up with the cutting point.

Comment: The time delay between reaching the synchronous speed
and the output of the synchronised signal can be set using a
