Fanuc Oi-MC control. Keep getting alarm 2082 Axes zero point return requested. Machine will not move in zero return or jog. When I switch it to handle mode it throws message 1210 APC not at ready position. Can not get the machine to move in any direction. Checked the battery voltage at the back of the control and it reads 3 volts which is correct. Problem is somewhat intermittent, once in a while after the machine sets you can get the machine to home out but then its throws the same alarms stated above. Any ideas? Thanks
