    Hello. I'm helping a mate get a 7d simulator working. It has 6 AC servo drives and Dorna AC drivers.
    Did some initial testing and found a Dorna AC servo driver EPS-KA01D2123-6000 which has blown up. Looks like some sort of short an a number of components blown off the board.

    The actual servo drive tests ok. No shorts.

    Does anybody know if there is a schematic for the circuit boards avaliable - for possible repair.
    Are 2nd hand replacements available anywhere?
    Or is there an equivalent AC driver that I could purchase and set up to run with the existing servo as a replacement for this one.

    Thanks
    Any information appreciated. This is the 1st time I have done any fault finding on a machine like this.
