VFD Fundamentals - Houston

Facility technicians, electricians, service engineers and anyone who is interested in working with VFDs and require an entry level class.

At the completion of this 2 day VFD fundamentals course, students will be able to understand the hardware components making up an AC PWM VFD, the safety hazards involved, basic troubleshooting and the approaches for setting up basic motor starting applications.

PWM VFDs are unique electrical devices that utilize high speed switching technologies and power electronics that require a unique skill set in order to successfully apply and troubleshoot this type of motor starting. Understanding the VFD hardware topology, motor impact and load response is crucial to successful motor starting. Knowing how to program VFD I/O functions is essential for coordinating specified controls within any application. Above all, knowing how to work with VFDs safely is paramount if any work / troubleshooting is to be performed. Real world lab applications are used to conceptualize the topics and familiarize the individual with how VFDs actually respond and how the VFD and motor should be installed, programmed and tested. Additionally, practical and safe approaches for troubleshooting are covered in addition to understanding fault data.

• VFD Safety considerations.
• PWM technology, power electronics and the fundamentals of power converters / inverters.
• Power wiring and motor installation requirements.
• Controls - physical wiring and programming of VFD I/O points.
• Fundamentals of VFD motor starting and basic parameter setup and tuning.
• Safe methods of powering and testing VFDs and repair options.

Gaining Access:

Upon arriving at our training centers, follow signage and any other directions you may have received before arriving for your event. Our staff will greet you upon arrival and take you to the appropriate training area. You will be asked to sign in for all events so that we can track building occupants in case of an emergency situation.

What to Wear:

Due to the nature of our training facilities and other events taking place, we ask that you wear business casual (or appropriate PPE if your event requires PPE in lab exercises) while in the facilities. Please do NOT wear shorts, open-toed shoes, or loose clothing that can get caught on equipment in the lab spaces.

Safety:

Our labs are working labs, as well as training and testing spaces. Equipment may or may not be energized with control voltages as well as three phase power. We ask that you do not open or operate any equipment within the facility without discussing with your host. Eaton staff will provide you with information on gathering points, as well as exit paths at the start of your event.

In addition, Eaton can customize training specific for your organization on a variety of other topics. To learn more visit www.eaton.com/electricalworkertraining or email [email protected].
