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!

Hi Spud!
I have finaly managed to fix the faulty board after i replaced a dead cmos ic.But i still have need of some boards from this machine like the main interface board. It looks like the one and only Ferranti IC located there is dead as well. If you still heve the old boards i am interested buying them.
