    Hello everyone!

    New member here and knowledge thirsty.
    So here goes my first question...My lathe X-axis drive(PKS-DIGIPLAN SD2) lights up a red LED. Then a TO-220 Transistor or maybe a triac, I have no idea what this may be found dead. It has a printed code _PKS0320 but nowhere in the Net I was able to find data or a cross reference for this . So, I have no idea what it may be . I am just guessing this has to be a triac. In the Parker SD2 drive user guide though, only block diagrams I have found so far. Electronic schematics of the boards... nowhere.

    Just in case someone of you had access to a stepper drive like this and happen to know what kind of IC this is please help.

    regards!
