If
SET M53 or WAIT M53 is driven, for instance, BFM113 b7 is turned
ON
after bo, b2, b4, and b5 are turned
ON.
At the programmable controller side, each aux. machine is driven in accordance with the M-code
data.
Since, unlike a WAIT M instruction, a SET M instruction does not require any start command, it serves
as a convenient instruction
to start the succeeding positioning operation (WITH MODE), while the
programmable controller drives the aux. machine.
