A typical variable frequency drive (VFD) can have anywhere from a few hundred to well over a thousand parameters. Which parameters are important and which ones not so much? Arguably, one of the most important, and sometimes. Maintains a stable V/f ratio, allowing for proportionate changes in voltage and frequency.
