Hello All,
Wish you all a happy new years 2021!
We have an Okuma lathe LB 300 R with OSP-U100L controller, we have been getting this intermittently 1181-11 MCS DIFF OVER X AXIS ERROR and the lathe use to run after turning off for a while and switch back-on until now as the x axis does not move nor the reading changes in display in jog. WE had a humming sound before in jog as it would alarm out MCS DIFF after moving an mm or so.
No mechanical damage observed and ball screw is in good condition. we connected the z axis motor wires to x motor and it works fine. Also the z wires from drive have been connected to x motor it works fine as well. But when we connect the x wire from drive to either motor they doesnt work. We have come to conclusion that the wires, motors, ball screw seems to be ok. After doing this exercise of disconneting motors now we no longer receiving any error alarm, just that axis will not move. we checked the drive and it does not have any visible issues, Does anyone know of what could be the problem? does it have to do with any parameter/software issue?
