I have a dead ABB ACS550 drive that won't do anything.
Is this a common fault with these and can they be repaired?
I think it may have over heated.

I also have a smaller ACS550-U1-012A-4 drive that is now
doing the same thing.
I've heard that they can be rebuilt or repaired by replacing some parts.
