[Pr.18] M code ON signal output timing
Set the timing of outputting the M code ON signal.
Select either the WITH mode or the AFTER mode as timing of outputting the M code ON signal.
• An M code is a number between 0 and 65535 that can be assigned to each positioning data (shape).
• Programs can be coded to read the M code from [Md.25] Valid M code whenever the M code ON signal [X4, X5, X6, X7]
turns on so that a command for sub works such as clamping, drilling, and tool change corresponding to the M code can be
issued.
• When the AFTER mode is set in the speed control, the M code is not output and the M code ON signal [X4, X5, X6, X7] is
not turned on.
• The M code ON signal output timing can be set for each positioning data with the positioning option ([Da.27] M code ON
signal output timing) of the positioning data.

Buffer memory address
The following table shows the buffer memory address of this area.
■ Default value
The default value is 0: WITH mode for all the axes.
WITH mode (setting value: 0) AFTER mode (setting value: 1)
An M code is output and the M code ON signal [X4, X5, X6, X7] is turned on
when a positioning operation starts. An M code is output and the M code ON signal [X4, X5, X6, X7] is turned on
when a positioning operation completes.
