[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.
WITH mode (setting value: 0)
An M code is output and the M code ON signal ([Md.31] Status: b12) is turned
on when a positioning operation starts.

Positioning
[Da.1] Operation pattern
*1 m1 and m2 represent the configured M codes.
• 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 ([Md.31] Status:
b12) 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 ([Md.31] Status:
b12) 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.
