An AC drive, which is often called a VFD drive, is a device which you use to control the rate of an electric motor in your application. A drive will alter the frequency and voltage of the electric supply to control rate. Frequency (or hertz) accounts for the motor’s speed. The quicker the frequency, the more rapid the RPMs. Appendix B in the manual is a helpful list of parameters that allow the user to record their settings in case the drive goes bad and parameter settings are lost.
