About Sumitomo Drive Systems
Sumitomo variable frequency drives are used in industrial applications where dependable motor-speed control, efficient operation, and reliable equipment performance are essential to daily operations.
Control Concepts Dallas supports current and legacy Sumitomo inverter equipment used with conveyors, pumping systems, material-handling equipment, process machinery, gearmotors, and other demanding motor-control applications.
Our technicians diagnose and repair variable frequency drives, power and control electronics, cooling systems, communication hardware, and related motor-control components. We can also help evaluate repair, replacement, retrofit, or modernization options for aging or difficult-to-support equipment.

The Repair Process
When a Sumitomo VFD or electronic motor-control system develops a problem, Control Concepts Dallas evaluates the equipment and surrounding operating conditions to determine whether the issue originates within the drive or elsewhere in the application.
Our technicians review incoming power, fault history, drive settings, communication systems, cooling components, connected motors, and mechanical loads. When appropriate, the equipment is inspected and tested through controlled power-up and functional motor testing.
Once the cause is identified, we determine whether repair, replacement, retrofit, or modernization is the most practical solution.
Most drive failures can be avoided through preventative maintenance.
