- ✅ C'mon over to realpars.com where you can learn PLC programming faster and easier than you ever thought possible!

==========================
Today you will learn about VFDs. Specifically, what they are and when do we use them with automation and PLCs.
What exactly is a VFD? Well, it stands for Variable Frequency Drive. They are used for running an AC motor at variable speeds or let them ramp up their speed to give them a smooth startup.
Some people simply call them drives. They work by adjusting the frequency of the motor to adjust the rpms.

Thanks for the insightful comparison of electronic components to hydrologic systems . This opened a couple of doors quickly for me. To get an understanding of how a PLC interacts with a VFD has given me some confidence in my new job as a Flexographic printing Mechanic. It is my hope to not only comprehend but to be able to program fully automated six color presses to accommodate changes in production requirements across a wide variety of material and ink types. This work is gratifying and worthwhile for me and your program is now on my radar. Keep up the good work many thanks.
Thanks for your comment, Jeffrey!
The world is quiet here..
Best animation video on youtube.
Thanks a million, great to hear that!
Always starting with the principles to create a strong foundation. That's what I like about your videos.
Thanks for sharing your positive feedback! Great to hear.
They do lay down the fundamentals quite well in explaining things in every video fundamentally. I really appreciate that about them as well as the fundamentals help immensely in understanding and they do it in very simple explanation and animation. It’s just awesome.
Dear, please share your knowledge on points 1) How to do wiring , i mean power wiring + control wiring of a VFD and its hook up with PLC 2) What are the configuration settings to be done inside the VFD for Siemens and Allenbradley ones 3) how to build a control logic for the same by using PLC programming. Kindly do the needful. You people are awesome, love u all
Hi Hara!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
Just finished watching your "what is a VFD?" video and, once again, the explanation was excellent, especially useful was the analogy of the water control pipeline. I started to read up about VFDs on a well-known online encyclopedia and was blinded with science. Your explanation was pitched perfectly and just what I needed as I'm working on updating our PLC to control an inverter for a water pump. Perfect, keep up the good work. Cheers!
Awesome, thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback!
If you ever have any questions, feel free to reach out to us.

Super awesome explanation! Thank you Sir! What a smooth instructor 💯🙌 I treasure this channel now...I rarely come across lucid and well articulated information like this. Thank you!!!💯👍🙌🙌🙌🙌
Thanks for your support! Happy to hear that.
Widely used as well in HVAC, especially in FAHUs, AHUs, and Chilled Water Pumps.
Very informative. Needed to touch up my understanding of one when I wondered as I was supplying line voltage to one. I never fully understood them.
Great to hear! Keep up the good learning :)
Exceptional video lesson with an impeccable subject of a state-of-the-art equipment which is becoming indispensable in the most varied processes.
It is fascinating to understand the conversion of AC input energy into DC energy and going out simulating an AC senoid through the width of pulses having the ability to control the speed of electric motors by frequency.
Thank you very much and congratulations on the excellent work.
I'm from the city of Manaus, in the State of Amazonas, Brazil, country, located right in the middle of the Amazon rainforest, where incredibly there are several of these equipment, and I accompany you.
Our pleasure! Thank you very much for your kind comment, and for sharing that with us.

Thanks
Thank you for this video I learn great things 🌹❤️
You are very welcome, Emad!
Thanks for the video this just made my idea of a off grid induction motor and centrifugal pump to pressurize the water to drive pelton turbines for my hydro electric system a reality for my bitcoin mining operation, simply put much like the video i was wondering how i could control the pump speed for pressure to drive the pelton turbines to have more control on the overal out put of the generators also the electric motor is also powered by the same generators currently figuring out how to switch power sources for shutdowns for maintenance purposes where i would have to hydro systems to switch between to service but maintain electricity.
Thanks for helping

Thank you
Happy to hear! you're welcome.
Nice Explanation
Thanks and welcome!
Great video!!
Thank you!
Very interesting
vfd controls the speed of the motor by converting AC to DC then back to AC with different frequency and it can be wired to plc to make the task automatic and get rid of a stupid operator! can't find any easier and straightforward explanation... GREAT JOB
Thanks a million for your kind comment, Yousfi! We appreciate your support.

Thank you. I will pass your request on to our creator team.
Hi,
What happends if you connect for exemple a cnc machine spindle (Ac 3 phasis) to 3 phasis electric network ?
Best regards
Thanks for the video I thought VFD would give more torque at the initial start up to reduce mechanical load than it can regulate it either manually or automatically by using PLC.
Thanks for the info sir
You're very welcome!
very very good describe sr thnx
Nice video, thanks :)
Glad you liked it!
