ECN Forum Forums General Topics of the Trade General Discussion Area VFD BURNING OUT MOTOR BEARING

We have recently installed vfd's in exixting circuits and now one of the motors has burned out and they are blaming our VFD. The vfd s are not even programmed to do any control as of yet just off and on.
Can it be the VFD the controls company is saying that our VFD's are causing a voltage across the bearings?
