About Danfoss Drive Systems
Danfoss drive systems are used in industrial and commercial motor-control applications where dependable speed regulation, energy efficiency, and consistent equipment performance are essential to daily operations.
Control Concepts Dallas services current and legacy Danfoss equipment used throughout industrial plants, commercial HVAC systems, water and wastewater facilities, material handling, packaging, and other demanding motor-control environments.
Our technicians diagnose programming problems, damaged electrical connections, cooling failures, communication issues, control-circuit faults, and problems involving connected motors. We inspect and test the drive, back up existing parameters when appropriate, and verify operation through controlled power-up and functional testing.

The Repair Process
When a Danfoss drive 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, electrical connections, cooling components, communication signals, connected motors, and operating conditions. Before applying power, we inspect and test the drive’s power sections, back up existing parameters when appropriate, and verify operation through controlled power-up and motor testing.
Once the cause is identified, we determine whether repair or component replacement is the most practical solution. Proper cooling, clean operating conditions, secure electrical connections, and periodic inspections can also help reduce future problems.
Most drive failures can be avoided through preventative maintenance.
