Fanuc Robcut EDM - "Short" fault.
I am working on a Fanuc Robocut a-OA CNC EDM Wire Cutter, Type A04B-0301-B033 (1993 Model). The machine keeps saying that the EDM Wire is "Shorting" even when dry running with no workpiece fitted. Does anyone know what the likely causes are for this problem. We can't find any reference in the manuals to this problem other than checking the actual wire for shorts - which we have done. We have changed the Discharge Cables and Board. We have checked the fluid - there is no contamination (the machine sensor shows a good reading for the fluid). We have also disconnected the electrode leads but still get the "Short" warning.
Have you had this problem before and been able to correct it?
Does anyone know what the Short sensing circuit is?
