Top 5 VFD Parameter Changes

Through VFDs, electric motors can be used to run a wide array of applications to achieve control not possible with across-the-line operation or mechanical means. Through VFD controlled motors, users can optimize system efficiency by matching motor speed to maintain exact system demand.

As with all electronics, VFDs have advanced in capability and function over their long history, providing more system control to help eliminate external devices and integrate with programmable logic controllers (PLCs).

Due to these innovations, it is perfectly understandable that you may be overwhelmed by the prospect of programming VFDs for your application. However, most applications require only the most basic settings to operate the motor. That is because VFDs are designed and engineered to make the complicated simple. They can even use integrated setup wizards to get you up and running quickly.

In most cases, the VFD’s default settings will be sufficient for your application and not require any adjustment. Typically no more than a dozen settings are adjusted for an application. This article details a list of the top five parameter settings programmed by VFD installers to help you better understand what your setting and why.
