Are you refering to a flexpak drive?

A VFD drive

 

[Ken Roach]

A-B has made VFDs for decades, and there are at least four hardware families with the name "PowerFlex".

Please post the model, and ideally the size (HP or kW or Amperes) or part number of the drive, and folks may be able to direct you to a troubleshooting and repair guide.

as stated we need more information the origenal manufactured date may help
early VFD's used SCR's on both the incoming power bridge and as well as the output power section. ether way it's time to consider an upgrade other components may be ready to fail as well. Some VFD's just aren't worth the time and expense of a repair
