    Default Fanuc OM can't run M code in Memory mode

    Dear all.
    I have my trouble is: My CNC machine( it's using Fanuc OMC controller, with PMC axis control) can't run M-code from Memory mode, but I can let it run correctly in MDI mode.
    Does any one can guide me to fix this problem?
    Thanks for your help.
    Nam.

    When you press the start cycle button is that lit(green color) or is not:
    1.If start button is not lit you must check the following:
    -diagnose 122 must be XXXXX001-means machine is in auto mode
    --diagnose 120 XXXXX1XX---this bit must be 1 when you press cycle start button
    -diagnose 121 XX1XXXXX this bit ia feed hold signal
    2.If the start button of cycle start is lit wth green colour but the machine do nothing check following:
    -diagnose 700--all bits on 700 line must be 0 if everything is ok,if any bit is 1 when you press cycle start on diagnose 700 line please come back and let us know what bit
    -diagnose 701 bit 5 XX0XXXXX must be 0 in normal operation

    Please check and let us know

    It seems this solution is absolutely correct. I believe it will work normally again
