Terminal 5 at London’s Heathrow Airport opened in 2008 with over 800 VACON AC drives helping to reduce energy consumption and noise levels.
Control Concepts knowledge of VACON AC drives covers every industry served by VACON.
What Is an AC Drive?
An AC variable speed drive efficiently controls the speed of an electric motor, matching the speed to demand and saving energy. It can also convert energy from natural and renewable resources such as the wind, tides, or sun. AC drives also transmit energy to the electrical network or for local use.
AC drives are used in hybrid technology as well, combining conventional energy sources and storage to create total energy management solutions.
- Enhance process control
- Reduce energy usage and efficiently generate energy
- Decrease mechanical stress on motor control applications
- Optimize the operation of various applications that rely on electric motors
75% of AC drives are used on pumps and fans. If used in every suitable application, AC variable speed drives could reduce global electrical energy consumption by 10%.
Control Concepts provides service for VACON AC drives backed by over 30 years of experience in drive repair, service, and support.

Control Concepts Service and Repair
Common Drive Failure
- Drive doesn't run the motor
- Drive keeps blowing fuses or tripping breakers
- Loose connections
- Non-functional cooling fans
- Software or programming problems
- Circuit board failure
The Repair Process
We check the motor drive and terminals for substandard connections which can be caused by anything from heat cycles and mechanical vibration to reusing or over-tightening torque screws.
We conduct diode and IGBT tests on the input/output power sections before applying power to the drive unit. This is to protect against further damage from a short.
We power up the unit and perform amp readings and output frequency tests, slowly increasing the voltage until the rated input voltage of the drive is reached.
If everything functions properly, we use the drive to run a motor through basic jog functions after backing up existing programs. If the motor does not run, we check the output voltages and current ratings going to the motor to check drive function for motor rotation.
Most drive failures can be avoided through preventative maintenance.
Control Concepts provides 24/7 service and support.

Did you know? The Seikku sawmill in Pori, Western Finland was the first to receive a VACON CX AC Drive which was delivered so quickly there was no time to paint the front panel.
*Danfoss and VACON joined in January 2016 to become the second-largest AC drive manufacturer in the world.
