This one-day class on variable frequency drives consists of concept, application, installation and maintenance. The course will cover general VFD theory of operation that is not vendor specific. Also discussed are startup, programming, troubeshooting, motor selection and harmonics. Whether it's called a freak, a drive, a VFD or an AFD, what was once limited to very large horsepower-expensive units has found its way into everyday applications.
Note: Accessing a refrigerant system requires an EPA Certification.
