Re: motor failure
generally in engineering you look for a single point of failure. If three motors have stopped working then most likely one thing has failed that can stop all three motors
I would look at stuff like your ground connections (ground stud or the terminal block)
or make sure your SW guys didnt decide to test new SW when you were not there.
It very rare for two things to fail at the same time. Extreemly rare for three things to fail all at once.
Look for the single link that ties them all together.
