Variable Frequency Drives

This cutting edge, hands-on training program will expose the “magic” in the mysterious box known as the VFD or Variable Frequency Drive. The VFD has evolved to meet the needs of today’s manufacturing facilities and their requirements for the future. Single speed or constant speed drives served industry well for over 100 years. But these systems have a crucial drawback in today’s fast-paced environments; the speed of the motor is dependent upon the frequency of the AC that we power it with.
Variable Frequency Drives have overcome this limitation by utilizing the power of solid state devices and microprocessors. The drives are capable of taking a fixed frequency power in and delivering almost any frequency power out. But this technology also has certain drawbacks for the folks who must maintain it; it is much more complicated and the maintenance and troubleshooting techniques are quite different than those for the single speed drives.

This hands-on training session is designed to take you through the complete system of VFD: from the basics, through operation and setup, to troubleshooting. All of this training is conducted on state-of-the-art simulators in a safe environment. Making a mistake in our lab won’t cost you a cent!
Attending this exciting new program will provide you with the skills and knowledge to successfully operate, apply, maintain, and troubleshoot the Variable Frequency Drives you encounter in your plant each day. Come and demystify the “magic” in the box!

Who Should Attend

Maintenance mechanics, supervisors, electricians, plant engineers, HVAC mechanics and any one else directly involved with selecting, maintaining, or operating Variable Frequency Drives. VFD’s are found in many types of rotating equipment such as: compressors, pumps, conveyor systems, fans, and other such equipment. An understanding of basic electricity is helpful but not required.
