Repair or Replace a Failed VFD? How to Decide

Technician inspecting AC drives inside an industrial control cabinet during troubleshooting

When a VFD fails, the pressure to get the line back up is immediate. But making the wrong call, repairing what should be replaced or replacing what could be repaired, costs time and money. Learn what actually determines whether repair or replacement is the smarter move for your situation.

Common DC Drive Failures and What They Mean

DC drive failures can look straightforward but rarely are. A motor that won’t run, repeated fuse failures, overheating, or a failed board often point to something deeper in the system. Learn what common DC drive failure symptoms mean, what to check, and when it’s time to call for service.

What Thermal Imaging Can Reveal in Industrial Systems

Thermal imaging helps industrial facilities find heat-related problems before they become failures. From loose electrical connections and overloaded circuits to failing bearings and stressed drives, abnormal heat is often the first sign something is wrong. Learn what infrared inspections can reveal and how they fit into a smarter maintenance program.

What Is a Yaskawa Drive? Applications and Reliability
