Applied VFD Controls and Service - Basic - Denver

Facility technicians, electricians, service engineers and anyone who may be responsible for the installation / setup / troubleshooting of VFDs.

At the completion of this 4-day basic level course, students will be able to utilize all I/O functions to apply control schemes across several applications, understand the hardware components making up an AC Pulse Width Modulation(PWM) Variable Frequency Drive(VFD), how to utilize fault information for hardware troubleshooting, and know how to safely power a VFD during troubleshooting.

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 control schemes and effective motor starting characteristics. Generally, there are two scenarios facing a VFD technician when installing or troubleshooting a VFD: Either you have specified drawings from an engineered solution, or you are applying a VFD into your application yourself. Both scenarios require the technician to fully understand the control capabilities of the drive and how the various internal systems function in order to troubleshoot them. Real world applications are used to implement basic open and closed loop control schemes. VFDs present electrical hazards and you will be shown safer methods of powering VFDs during troubleshooting as well as repair considerations and methods.

• VFD safety considerations
• Power terminal locations for Live-Dead-Live measurements
• Fundamentals of open and closed loop control schemes
• Entry level fieldbus communication for monitoring and control
• Control schematics and physical wiring of VFD I/O points
• Selecting VFD applications for testing / tuning of open and closed loop systems
• Fundamentals of troubleshooting VFD software and hardware faults / test and measurement instruments
• 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].
