Looking for some assistance here. currently have a NX100 ES165N we are refurbishing. on our known good test controller we have no issues running this robot and there are no unknown noises coming from it.
We have currently grabbed the matching controller for this robot and when we power it up we are getting a grinding noise coming from the R & the B axis motors when we try to move them. Currently we have tried replacing amplifiers, power supply, axa01a board, JZNC-NIF01 board, power supply contactor unit and the converter. with no success. I've looked into the x11,x21,x22 terminals ensuring there are no burn marks, loose wire and also cleaned the connectors.
would anybody happen to have any information that may help lead up in the correct direction?
