Drive Repair and Drive Health

diagnose and repair problems with ABB drives and Siemens controls

Quad Plus technicians are manufacturer trained. That gives us the ability to expertly diagnose issues with drives because of our experience with OEM manufacturers and exclusive access to original OEM documentation, including manuals, literature, and schematics.

Once a drive repair is completed, drives are put through a load stress test to ensure it will perform adequately and safely once it is back in production. Our expert repair technicians check the drive health by taking readings and performing advanced testing.

IGBT (insulated gate bipolar transistor) can degrade over time and become dangerous to operate due to the risk of explosion. Restoration must be made, especially if drives have been shut down for an extended period. Our team can perform the extensive work necessary to test IGBTs and reform bus capacitors for safe operation.
