: m1 and m2 indicate set M codes.

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

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.
