M FUNCTION STROBE 1
This signal informs that the 1st set of miscellaneous functions (M code) is commanded with the
automatic operation (memory, MDI) machining program or manual numerical command input.
The miscellaneous function is also called the M function, and is used to issue miscellaneous functions
such as ON/OFF of the cutting oil, and normal/reverse/stop of the spindle, etc., for the target machine.
This signal turns ON when:
(1) The 1st set of M function (M code) is specified in automatic operation (memory or MDI).
(2) M function (M code) is specified by manual numerical command input.
The signal turns OFF when:
(1) "M function finish 1" signal (FIN1) or "M function finish 2" signal (FIN2) turns ON.
(2) Reset condition occurs.
Refer to the "In auto operation" signal (OP) section for details on the reset conditions.
(Note 1) When built-in PLC is used, four sets of M functions can be specified at the same time the
relation of the machining program and M function strobe is shown below.
Machining program ..... M03
(Note 2) During operation with miscellaneous function lock (AFL signal ON), the M function strobe
(MF1, MF2, MF3, MF4) will not be output. However, this signal will be output when the M
code is commanded independently (M00, M01, M02, M30).
(Note 3) Since M98 (subprogram call), M99 (return from subprogram), etc. are handled within the
controller, M function strobe is not output.
(Note 4) The M function strobe will not be output when the M function is output if the "M function
finish 1" signal (FIN1) or "M function finish 2" signal (FIN 2) is ON.
