(8) [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.
An M code ([Da.10]) is a number between 0 and 65535 that can be assigned to each positioning data.
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.
The 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 [X4, X5, X6, X7] turns ON so that a command for the sub work (e.g.
clamping, drilling, tool change) associated with the M code can be issued.
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.
WITH mode AFTER mode
An M code is output and the M code ON signal is turned ON when a
positioning operation starts.
An M code is output and the M code ON signal is turned ON when a
positioning operation completes.
