Long shot this one but does anyone have a pcb schematic for a Kinco 2m2280N stepper driver?

I got these one from Gary at Zapp a long time ago but his site shows none in stock. I will need to speak to him tomorrow to sort out a replacement.
Can you think of any problems with using differing types of drivers on the same control system? I can swap things around to have my remaining kinco drivers on the X and Y axis and say have a different one on the z axis.
Sorry cant help, what happened to your forum avatar?
Lee, I don't think I ever had one. Never got round to it. I'm sure its on the list somewhere.
No Problem what so ever, it's done often.Quote:

I can also post what I find here in case it helps others with fixing them.
Bit of an update on this. I have the driver apart on my bench and have found the cooling fan faulty and a shorted IGBT. The fan is easy but waiting for someone to see if they can get me a replacement IGBT.
With the faulty IGBT removed from circuit the existing fault disappears and now says that it cannot find the motor which is correct seeing as its not connected.
I will update again if I can get the correct parts and get it working.
If there are any protection diodes on the output, check these as they often go with the IGBTs.Quote:
