Learn Variable Frequency Drives: wire & program a VFD
What you'll learn
- VFD power & control wiring
- Quick start up
- VFD programming
- Analog & digital inputs
- Output relay wiring & programming
- Display, basic & advanced parameters
- Advanced VFD concepts
- Fault codes
- A basic understanding of electrical circuits
- A basic understanding of induction motors
- Understand the difference between voltage and current
- Understand the difference between 3 phase & single phase
- Understand the difference between AC and DC, although not critical
- Have a basic idea of what a VFD is used for, although not critical
- Understand the measurement of frequency in hertz, although not critical
In this course we will be working with the Allen Bradley PowerFlex4 variable frequency drive.
You may have heard about VFDs, seen them in operation or you might have even installed one or two yourself. Whatever your experience level is with VFDs this course will give your skills a major boost, especially for the model that we will be working with. Using the quick start manual provided in the course, together we will learn step by step the art of wiring and programming a VFD from scratch!
In a nutshell:
We start off by pulling our VFD out of the box to familiarise ourselves with it.
We then learn how to protect the drive and wire it up to our motor for the first time.
Resetting the drive back to it's factory settings is next which will prepare us for our first round of programming.
After powering-up our drive we use the keypad controls to fire up our motor and explore some display features.
Once we have graduated from the keypad controls we will learn all about remote control wiring.
Gradually adding levels of complexity to our installation we move onto using the relay outputs and analog inputs.
We then explore some advanced wiring and programming concepts with plenty of demonstrations.
To bring it home we look at possible fault situations and the fault codes that relate.
In detail we will learn:
Motor parameter entry
Start source, stop mode and speed reference
2-wire, 3-wire and potentiometer control
Ramp time adjustment
Relay output wiring and selector programming
SINK vs SOURCE configuration
External supply control
Multiple preset frequency output
0-10volt and 4-20ma analog control
PWM output frequency
Voltage band adjustment
And much more.............
If you want to get the edge and learn all about VFDs I'll catch you in the course.
Who this course is for:
- Beginner or advanced technicians curious to learn more about VFDs and motor control
- Anyone wanting to learn how to connect a VFD to a motor
- Anyone wanting to learn how to program a VFD from scratch
- Anyone interested in learning how to wire up the digital or analog control inputs of a VFD
- Anyone curious about how VFDs control motors
Ok, I'm not a real wizard but I am a real wiring expert!
I specialise in Electrical Controls and have worked at the top universities in Australia, including Melbourne University, Monash University, RMIT and La Trobe University. I have also done specialist controls work at The Department of Defence - Science and Technology Centre and on the Melbourne Public Transportation Network.
My experience in controls covers PLCs, HVAC, Electromechanical Controls, Instrumentation and Pneumatics.
In my spare time I like to tinker with vintage hi-fi gear, play guitar, walk the dog and work on my jump shot.
