(3) Resetting of M-codes
M-codes can be reset by setting of the M-code output devices to zero.
Use this method during positioning control to perform operations unrelated to the
servo program, such as when it has been difficult to output the M-code during the
previous positioning control.
However, M-code is set55 during the speed switching control or constant-speed
control, the M-code output of the servo program takes priority.
