Came into an odd problem yesterday. F200 8.3 /15. Apparently servo motor was replaced on the off-shift. Tech supposedly single axis mastered the one arm and then calibrated. As soon as they would try to jog the robot they would get a servo fault on the drive and the TP would lock up. For what ever reason they decided to start loading images.... They said they had the same issue with all the images they tried.
When I came in they had just installed an image from 2020. I single axis mastered all 6 axis and then calibrated. No issues. Loaded the latest AOA backup and we are back in production. Any ideas on what could cause their issue with it locking up?
