Purpose of Training:
This course was created to bring students up to speed in their knowledge of variable frequency drives (VFDs) as quickly
and safely as possible. It includes "hands-on" demonstrations for skills improvement and is specifically designed for
maintenance technicians and others working in industrial plants and commercial buildings, or wherever variable speed
control applications are found. It is also a great refresher for experienced electricians and engineers. It provides a practical,
real world VFD education. Students are also encouraged to describe their own unique VFD applications during the class so
that after discussion they can go back to their workplace and immediately apply what they’ve learned.
Overall, the purpose of this course is to increase the skill and confidence needed to get the most out of your VFDs by
teaching students how to improve VFD control and efficiency, troubleshoot and fix VFDs, reduce equipment downtime,
eliminate chronic VFD problems, lower the cost of VFD operation, and alleviate the need for hiring costly outside service
contractors, all while establishing a culture of safe work practices among employees. This course can also be adopted as
part of a company’s regular Qualified Electrical Worker program.
Course Overview
This course provides a solid foundation for those needing to understand Variable Frequency Drives. It
enables students to service their own VFDs from top to bottom. It is practically designed around common
applications involving HVAC, pumps, fans, conveyors and other specific applications including those that
require constant torque operation. It covers AC motors, VFD configuration, component layout, control
methods, installation requirements, operation, setup, programming, preventive maintenance, power
