Variable Frequency Drives

CAD Control Systems has experience designing/integrating and building systems utilizing variable frequency drives.  Using VFD’s will offer benefits far greater than using a traditional starter.


  • Energy savings
  • Smoother and leaner operation
  • Reduction in downtime
  • Increased reliability (Less wear on belts, drives, pumps)
  • Increased control (Speed, flow, pressure, temperature, torque, acceleration/deceleration etc.)
When used in conjunction with our HMI Control Stations, you also gain the benefits of easy viewing of VFD Motor Statistics to simplify troubleshooting and assist in fine tuning production.
Here at CAD our team can help integrate VFD’s in a number of applications. We have used VFD’s in standalone applications and in systems that include controllers (PLC or desktop PC). Not only can we help in the design phase, but we are also a UL listed panel shop.  We can manufacture, program, and test control systems before delivery to our customers. Our Engineers are available to help in the set-up, programming and tuning during installation and commissioning to ensure that all customer needs are met.

We have standardized on Siemens controllers and drives, offering a high level of quality, support, and reliability with a cost effective solution. At the same time, we can also incorporate a number of other manufactures VFD’s to ensure all customer needs are met.

We would love to hear more about the particular application that you are using, and what kind of goals/expectations you have for the system.
