Hi, I am new to this forum and pretty new to programming fanuc robots. I do have one program that is working in production under my belt. The company I work for recently bought a used M-20iA with a R-30iB controller. The robot was tested and worked before it was shipped to our facility. However, not upon start up the robot faults out and gives the error messages: SPOT-474 NM&OUT24v shorted after MCC SPOT-476 Fix Pwr short & then cycle I am wondering if a wire was vibrated loose during the shipment, however I have not been able to find anything in the cabinet. It looks like all of the boards are lighting up and working fine. I have been unable to find any documentation on these particular SPOT errors. Has anyone experience this error and knows how to fix it? Or does anyone have resources that may shed light on the situation? Thanks!
