Hello all,
I am brand new here . I'm limited in my controls knowledge but always trying to learn more.
I recently started working at a new manufacturing facility and one of the assembly lines I have aquired is having issues with AB ultra3000i servo drives failing. Apparently these drives are failing multiple times per year and are expensive to replace.
The drives are on a machine that has light curtains that are arranged in a manner that they are accidentally being interrupted during servo motions. The narrative I've heard is the light curtains are being interrupted so often therefore the drives fail prematurely.
Some other things I have noticed:
1. The enclosure for the drive is fairly warm. There are vents on the enclosure with a fan that appears to no longer work.
2. There are 9 bowl feeder controllers crammed in the same panel. I'm assuming this could create some noise?
3. I don't see ac noise filters. Don't know how critical these are.
4. There was some suggestion that the light curtains are cutting the 460V instead of using 24V to signal stop. Im trying to read the documentation to understand how it is typically wired. I assumed there was only one way to do this.
Can anyone point me in a direction or things I can look at?
