    Default Fanuc 21-t error 414 servo alarm

    Hello....I have problems with the control of my fanuc 21-t lathe.
    I would like to know if you can advise me because in my small country there is no fanuc specialist technician....
    ¡¡¡¡¡¡thank you very much!!!!!!
    data: sometimes when you leave the lathe on for 30 minutes or 1 hour with this error when you turn it off and turn on the lathe again the error disappears but then when you run the g code in automatic mode it works for a few minutes and then the lathe stops and the error 414 servo alarm appears again....
    ---------------------------------------------------------------------------------
    Alarm code: 1 on fanuc servo drive A06B-6079
    -------------------------------------------------------------------------------------------------
    On the lathe control panel : 414 servo alarm : x axis detec err
    414 servo alarm : axis detec err
    Any advice on what it could be?

    the EXP alarm is related to encoders
    as i checked my info i see there are 2 fans mounted on that driver.
    did you plugged out the control PCB to check if is any fan on the PCB?
