VFD 101​

Variable frequency drives (VFDs) are a commonly used piece of equipment across the industrial industry. This webinar will introduce what VFDs are and how they operate along with how they control electric motors. With a basic understanding of how VFDs control electric motors, this presentation will describe the positive effects a variable frequency drive can have on the system.


Understanding VFD De-rating​

The term de-rating a drive implies that a VFDis intentionally oversized to be used in an application that requires less power. If a drive isn't properly oversized and de-rated when appropriate it can result in your your drive overheating or even pre-mature failure! In this webinar, you will learn the different reasons why you would de-rate a drive as well as guidelines on how much the drive should be oversized by to ensure your VFD will work in your application for years to come.


Basic VFD Troubleshooting

VFDs are more advanced than ever before, but they have never been easier to troubleshoot. But what happens when the control panel doesn't give you a clear indication of what is going on with the VFD? This presentation will cover basic problems and nuisance trips that may be encountered with VFDs. Safety comments and wiring tips will be covered as well.


Correctly Applying a VFD to a Motor​

Selecting a VFD to a motor can be as simple as checking out the horsepower and the voltage of the motor - but when is it not so simple?  Check out this webinar if to find out when you should be oversizing your drive (de-rating) and if output filtering is needed.


Motor Technologies & VFDs​

Motors have come a long way since they were invented in 1832.  Efficiency is the name of the game and is driving new developments.  This webinar will cover the basics of standard induction motors and a run down of all the new high-efficiency motor designs like Permanent Magnet (PM) Motors and Synchronous Reluctance Motors (SynRM).


ACH580 & Applications

Drives & Fan Curves​

This webinar focuses on providing a basic understanding of fan applications and the cost savings potential of using variable frequency drives (VFDs).  Most fan applications are non-linear loads that follow the Affinity laws, or Fan laws, which means as you reduce the speed of the fan, the amount of your energy is reduced at a higher proportion.  Running most fans at 80% speed will result in almost a 50% reduction in energy usage!


VFDs and Fan Arrays

A fan array uses many lower HP fans to move the same volume of air as one larger HP fan.  The term “array” is used as usually the configuration is a rectangle or square consisting of rows and columns.  In this webinar, Peter Wilder will walk through the different ways you can use a VFD to control fan arrays and the pros and cons of the different methods.

VFD Schedule Generator

The VFD Schedule Generator is a simple tool to help generate VFD Schedules for Mechanical Drawings.  VFD Schedules are a great addition to the VFD Specification by allowing engineers to customize requirements for each drive more easily.  Make sure each of your drives has everything required to work exactly as they need to!


VFD Submittals for Engineers & Contractors​

The presentation will take a look at a sample project, starting at the one-lines. We will discuss how to read a one-line, with respect to identifying VFD information. We will discuss how VFD specifications and schedules come into play and recommendations for how Engineers provide that information to those who are bidding on a project. This will also include a brief strategy discussion for how to handle harmonic mitigation requirements. Then we will transition to reviewing a VFD submittal, and identifying those key items within the submittal that an Engineer needs to look out for, and what a Contractor needs to confirm proper coordination of their scope. We will also spend some time on VFD electrical schematics, showing how to read a schematic to identify hardware such as bypass contactors and confirm basic control logic. The webinar will use a typical HVAC project as an example. However, the concepts and information are also applicable to the Water & Waste Water industry and certain Industrial applications that you a plan & spec approach to the design and procurement of VFDs.

ACH580 and E-Clipse​ underload detection

With no additional hardware, VFDs can sense a loss of load a broken belt, broken coupling, dead heading, and other loss-of-flow scenarios in fan and pump applications.  Configuring the drive to monitor Torque is more reliable than monitoring current.  For bypass packages, the E-Clipse bypass can also monitor for these conditions.  This presentation reviews various loss of load conditions, current versus torque sensing methods, along with how to determine key data points to configure the VFD.


Active braking technology in VFDs

Tunnel applications for smoke evacuation often require quick braking and then reversing of fan direction.  There are multiple ways to brake and reverse a fan motor quickly.  This presentation will describe those methods along with a focus on the Active Front End drive solution.


PID control for HVAC drives​

This webinar walks through setting up a PID using the ACH580 Primary Settings. This settings-based configuration does not rely on memorizing parameters. Instead the configuration is intuitive with no need to use the user manual for assistance. This presentation is targeted toward VFD Start-up Technicians and Controls Contractors. However, Engineers and Owners will also find value in this webinar, as it shows the ease of use of modern VFDs... which ultimately leads to more design flexibility and potential cost savings.


Communications & Protocol

Proper BAS Integration to VFDs​

Communication is key!  Building Automation Systems (BAS) are widely used to control the climate in commercial buildings.  This webinar will go over the different ways to control the drive through the BAS - whether it's through hardwire I/O or over a communication protocol like BACnet MSTP.  Learn what to expect based on the way you want to connect and control the VFD.


BACnet Basics

BACnet is the number one HVAC communication protocol.  This presentation is intended for those who would like to learn more about BACnet.  The presentation is done from a VFD's perspective of BACnet.  The following are examples of questions that will be answered...  What is BACnet?  Why did the industry move to BACnet?  What are some tips and tricks for technicians to properly integrate a VFD onto a BACnet network?  What type of information can BACnet provide?  Why is BACnet key to an intelligent Building Automation System?

The Harmonics calculator tool was designed for engineers to easily estimate the total harmonics in their system and select the appropriate harmonic mitigating solutions to create a cost-effective design that meets IEEE-519 requirements.  This webinar walks users through the basics of how to use the Harmonics Calculator.


Advanced Harmonics: Drive Selection to Comply with IEEE-519

Building on the Harmonics 101 webinar we review different mitigation strategies available to achieve compliance with IEEE 519 including strategies for drives operating with Emergency generation. We cover... why we need to design for harmonic mitigation and look at designing solutions for desired outcomes and discuss effective use of specifications and VFD schedules.


Harmonic mitigation​ - AFE vs Passive Filter

There are a variety of solutions for mitigating harmonics.  This presentation provides a quick overview on harmonics and then focuses on two specific harmonic mitigation solutions – Active Front End Technology and Passive Filters.  Both solutions have their positives and we will review the features and characteristics to help determine which may be the best fit for your specific application.


Harmonic Mitigation Strategies: Choosing between an Active Front End vs Active Filter Solution​

There are a variety of ways to mitigate harmonics caused by variable frequency drives (VFDs). After a quick overview on harmonics, IEEE 519, and an assortment of mitigation techniques, this webinar focuses on comparing an Active Front End (AFE) drive to an Active Filter (AF) strategy.  AFE drives are considered a decentralized mitigation strategy and the harmonics are taken care of at the VFD.  In HVAC applications, Active filters are most often applied in a centralized mitigation strategy and the harmonics are taken care of at one point in the system.  Both strategies have their own unique advantages.  After attending this webinar an Engineer will have a better understanding of when to apply which strategy.
