M-code signal

BFM#5
Generally, other machine operations (e.g. tool change, drill) are operated together with the position-
ing operation.
Thus, an M-code is set within the PGU to inform the PC which auxiliary machine to operate.

A WAIT M instruction is an instruction to wait for a start command (in the loop or continue mode,
it is
also started by an
M

instruction. Both can be used alone or in combination.
