About This Course

This course covers all aspects of working with modern variable frequency drives (VFDs).

Generic terms that apply to all VFD manufacturers are covered. Wiring, programming and commissioning of different manufacturers are covered. In depth VFD setup is covered using professional drive commissioning software that is included free in the course. The student can follow along and adjust parameters using the software. Also included and demonstrated is VFD simulation software that replicates exactly the front panel buttons of a modern VFD. The student is walked through the steps of setting up a drive and important points learned over the years are covered. Periodic inspection and maintenance of VFDs and electric motors is covered. The tasks involved in maintaining and troubleshooting equipment are covered.

Other important information covered in the course include:

  • Working safely with VFDs and the hazards associated with VFD commissioning
  • VFD power and control wiring
  • Line, load and DC link reactors
  • The DC bus
  • Sink & source wiring

Norman Burton Education: My educational background is trades centric. I started a high school co-op in the early eighties and spent six years obtaining an Automotive Machinists’ license. Afterward, I started an Electrical Construction and Maintenance apprenticeship. Having successfully completed the academic portion of the apprenticeship at Durham College I became a C+M Interprovincial licensed Electrician in 1998. Working as an Electrician, I have completed numerous continuous learning programs such as: Arc Welding, PLC programming, Automation Technology, Teaching and Training Adults and a Masters Electrician Course. I became a licensed Master Electrician in 2007. Professional Experience: Working in the trades has been exciting and wide-ranging having worked in the construction, industrial and institutional sector. I have also spent considerable time working in the automation and controls sector. In 2007 I started an electrical business, Burton Electro Technical Inc. The business focus is primarily industrial controls, installations and troubleshooting. The business also builds electrical training equipment for learning institutions and private companies. Burton Electro Technical Inc. has customers throughout Canada and the United States. In addition to working in the Electrical industry I have been instructing part time since 2005 at Georgian College in the Electrical Apprenticeship program. While working in the Electrical Industry, I have travelled to the United States, Mexico, Japan, throughout Central Ontario and British Columbia. Current Endeavors: Owner / Operator Burton Electro Technical Inc. Instructing electrical apprenticeship programs part time at the Georgian College Skilled Trades Center in Midland, Ontario.
