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 your drive system because of our experience with OEM manufacturers (specifically Siemens & ABB) 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 safely and as required 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.

Technical Support Services

Whether you have questions that our technical support team can answer over the phone or complex issues that require expert support onsite or remotely, our goal is to provide fast repairs with the shortest downtime possible.

Technical Consulting

Are you experiencing issues with your control system, but concerned about changing settings? Our technical support team will discuss the problems and issues you are facing over the phone and via email. We can review fault codes, photos, and descriptions of the situation before sending you some recommendations and documentation to resolve the problem. We will get you back up and running by pointing you in the right direction.

Remote Support

Our experts are available to provide remote support sessions that allow us to connect to your control systems to gather information, system alarms, and fault codes. For safety reasons, we will not modify any operational parameters or control sequencing, but review the information to make recommendations. For new customers, our senior engineers will need to complete the qualification process before we can connect to your systems.

Onsite Support

Our technicians can also be dispatched to your location to provide onsite technical support. Before heading to the site, the technician will gather information and attempt to diagnose issues remotely. That way, we can ensure that a remote solution isn’t possible first, and then arrive onsite with the correct tools and parts to complete the repair. Our goal is to provide quick solutions with less downtime.
