15.4 Synchronization Between Part Systems OFF

15.4 Synchronization Between Part Systems OFF
Synchronization between part systems and feedrate change are turned OFF in a part of a machining program to eliminate a
synchronization between part systems by single block operation between part systems or variation of a machining program
feedrate by dry run. This function is effective mainly in blocking the cycle operation pause or feedrate variation in only some of
part systems when the sub part system control II function is being used. When loader control and ATC control which are
operated independently of machining are performed with a sub program or sub part system control, this function enables a
operation with synchronization between part systems in machining part systems and an independent operation in sub part
systems.
ON/OFF can be switched with the system variable or the PLC signal.
