[Pr.18] M code ON signal output timing
This parameter sets the M code ON signal output timing.
Choose either WITH mode or AFTER mode as the M code ON signal output timing.
[QD77MS4 operation example]
WITH mode ............ An M code is output and the M code ON signal
is turned ON when a positioning operation
starts.

1: m1 and m2 indicate set M codes.
(Note): Refer to Section 3.3 for input/output signal of QD77MS16 and Chapter 5 for buffer memory address.
Note: If AFTER mode is used with speed control, an M code will not be output and the M code ON signal will not be turned
ON.
An M code is a number between 0 and 65535 that can be assigned to each positioning
data ([Da.10]).
The sequence program can be coded to read an M code from the buffer memory
address specified by "[Md.25] Valid M code" whenever the M code ON signal turns ON
so that a command for the sub work (e.g. clamping, drilling, or tool change) associated
with the M code can be issued.
