40A Breakers popping when using CIMs

[galewind]

Hello everyone

We're having a small problem with our CIM motors.

When we're spinning 360 or moving slowly, our one side cuts out. You hear a clicking noise when it comes back on. Our victor on that motor powers down completely, fan and all, and then comes back on. I'm ASSUMING that means it's the 40A breaker popping.

What could be the cause of this problem? What could we do to fix it?

Sorry, I'm not familiar with the electrical portion of it, and we're wired according to specs, so I'm not sure what type of malfunction we could be having. I've switched the breakers around, but to no avail. Switching one breaker over another does increase the time that we can turn/move, but it still does cut out.

WE're using the default code as far as the power to the motors go. Is that our problem?

Any help appreciated.
