    Mazak QuickTurn 15n

    Hi,

    I bought Mazak QT15N 1990r, and after a few days it stopped working. When I turn it on there are this alarms : 204, 73, 128.
    The spindle controller was checked and proved to be good. there is propably problem with the MC617 on mitshubishi board (that is just my idea).

    One the Mitshubishi board there are:

    MC712 - the second and third LEDs light up green
    MC116 - Same
    MC724-1 - There are no LEDs on it
    MC617 - There are no LEDs light
    MC301 - One green LED on
    Last one - Mistshubishi CNC there's one green light on.

    Have you any idea what it can be?
