I've just had a quick scan of the G540 manual. How have you connected pin 10 and 12 on the G540? Have you tried connecting them with just a short bit wire?

The G540 uses 4 G250s internally, which don't have any form of fault output, so an individual axis fault should not cause the G540 fault light to come on.

I've got a wire - about 2 foot long which is connecting them both together, I'll have a go - and shorten it right up, but I doubt this is the issue, then again, the + and _ wires run right next to this wire at the G540 box. -I heard there was some form of overvoltage protection, so I assumed that was what was faulting.

Wow - I just found this thread..

Guy has exactly the same motors as me, and the same fault.
