I have a UP130 manipulator with XRC controller and the U -axis keeps getting serial encoder battery alarms. The battery's are fine and tested at 3.6V. Replaced them anyways and have same problem. This isn't a continuous issue. It may run for 8 hours or run for 1 hour but it does come back. So I found a thread where someone said they replaced the motor and that fixed the issue and another person said it was the wiring harness. So I would like to replace the motor first since it is much easier but I don't have a working motor in stock. I have a U- axis motor that we took off from another robot, same motor numbers, but the power lead connector is broken off of it. that's why we replaced it, it still worked fine and encoder is good. So what I'm wondering is can I take the encoder off this spare motor and put it on the motor I'm having encoder faults on? and if so does anyone have a procedure or advice?
Thanks.
