2 If one path is waiting because of an M code for waiting specified, and a different M code for
waiting is specified with the other path, an P/S alarm (No. 160) is raised, In this case, both paths
stop operation.
3 PMC–CNC interface
Unlike other M codes, the M code for waiting is not output to the PMC.
4 Operation of a single path
If the operation of a single path is required, the M code for waiting need not be deleted. By using
the NOWT signal to specify that waiting be ignored (G0063, #1), the M code for waiting in a
machining program can be ignored. For details, refer to the manual supplied by the machine
tool builder.
