    Unhappy Mazak QT100SG Alarm 406 - Memory Protect

    Hi All,

    I am having some issue with my mazak QT100 smooth C control.

    I am unable to edit or write any new programs as when you try to do so, this alarm comes up saying 'memory protect', I and the other operators of this machine have not set a password and would not know how to even do so. Can anyone help with this issue please.

    I'm not familiar with this control and may sound stupid but does that control have a key switch on the panel like older machines to stop operators changing programs?
    Regards Bob
