We are having 132 Encoder Err & 137 1Mtr Driver position err issues with our KRC 4. We can run a cold start after we EMD Master and the issue stops for a few days. If we don't power down the issue will return every hour or so. We are green to Kuka (New) and any help would be appreciated. We have had Kuka here a few times and the issue keeps coming back. 1st They had us change the motor and pulse counter. 2nd We moved a ground cable inside the controller. We had a main harness shipped in, but it dose not look like the correct one. It seems like more of a driver or hardware issue inside the controller. Thanks!!
