I am a teacher in Wisconsin using a UR5 with my machining and automation classes. I’ve had the robot for over three years now with no issues.
Today during my 1st hour class, the robot ran fine. The students shut it down when they were done with their project. I was supervising and everything seemed to be normal during operation.
I had a group of students during 2nd hour that wanted a demonstration on how to start their robot projects, so I powered on the robot at the pendant, took the e-stop off, and went to the initialization screen. I pressed the “on” button, but the “start” button remains greyed out. I have never seen this happen before.
I tried a restart, I checked to make sure the installation program is set to be the default program, and everything appears to be good there.
I am stumped, and figured I would make a post here while waiting to hear back from tech support.
Thanks for any advice!
