About Lenze & AC Tech Drive Systems
Lenze and AC Tech drive systems are used in industrial automation and motion-control applications where dependable motor-speed regulation, torque control, and reliable machine performance are essential.
Lenze acquired AC Tech in 1999, and many legacy AC Tech drives remain in service today. Control Concepts Dallas services current and legacy Lenze and AC Tech equipment used in packaging, warehouse logistics, material handling, automotive, converting, printing, and other automated industrial applications.
Our technicians diagnose drive faults, programming problems, damaged electrical connections, cooling failures, circuit-board issues, and problems involving connected motors or operating conditions. We perform component-level repairs, replace damaged parts, provide preventative maintenance, and offer onsite troubleshooting when needed.

The Repair Process
When a Lenze or AC Tech drive develops a problem, Control Concepts Dallas evaluates the equipment and surrounding operating conditions to determine whether the issue is within the drive or elsewhere in the application.
Our technicians review incoming power, fault history, drive settings, electrical connections, cooling components, connected motors, mechanical loads, and environmental conditions. Before applying power, we inspect the drive and terminals, test the input and output power sections, back up existing settings when appropriate, and verify operation through controlled power-up and motor testing.
Once the source of the problem is identified, we determine whether component-level repair or damaged-part replacement is needed. 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.
