These videos are incredible yaskawa... Also the presenter is amazing, his cadence and the timbre of his voice is perfect for these educational lectures. Very informative and EASY to understand presentation!
Such a great deep informative video related to VFD. Nicely described VFD applications, benefits, functions and internal components. Really understandable English with good accent. Great video for Electronics and industrial electrician and also for EE students. Really enjoyed whole video. Thanks for making such a great video.
From the late 80's when I saw and used my first Toshiba VFD controlling extractor fans in a yacht's engine room , to now, lots have changed. There is a huge number of competitors in the market. This Yaskawa video was one of the best I've seen on explaining how it works, from the newcomer to even the hard boiled user. Good job, Yaskawa, I might have to try your brand next time around!
I know im asking the wrong place but does someone know of a tool to log back into an Instagram account?? I somehow forgot the password. I would appreciate any assistance you can offer me
@Jayce Edward thanks so much for your reply. I found the site through google and Im waiting for the hacking stuff atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
Only if 20% percent of teachers are half empowering as this presenter , world would be a better place. Analogies are superb as well " like the rest of us , follows the path of least resistance"
Just finished watching the induction motor video. I’ll be watching this next. The dislikes on these videos must be from the competition. Very education videos!
22:35 I never saw snowballs listed in a description of hazards that NEMA enclosures are designed to protected against, but it seems Yaskawa's enclosure withstood the challenge. Well done videos.
This is totally outstanding! Very impressed by the presentation. The contract is exceptionally layed out in a very simple way that even a novice like me can understand. The video is well scripted and the voice is engaging. I just thought if you add sound effects to the futuristic graphics, it would make it that much more tangible.
You explained in a great way but I'm not done yet. My question is 1, why we convert ac into DC and then dc into ac to run a motor , why not directly apply ac voltages to control motor speed/frequency. 2, how VFD is energy saving 3, how VFD knows/ sense that motor wants to start or stop
We appreciate you taking the time to learn about "Drive Basics." We convert AC to DC and then back to a PWM ( Pulse Width Modulation) to control the frequency of the motor instead of being limited to 60 Hz. Wiring directly to AC would only run the motor at full speed. An energy-saving feature of the drive is its ability to control the speeds when commanded to run. Run/start commands and speed are required for a VFD to operate a motor. You can either provide external controls or control the drive from the drive.

Very good video. I just have one little bone to pick with some of the terminology. As someone who has spent the last 30 years working with all manner of electrical systems. and ad helluva lot of inverters along the way, This is a very good basic explanation of how they work. I'm not trolling you guys, but at ~17:32, you talk about how "...the DCCT's monitor the current on all three phases going to the motor". I guess technically that could be considered true, but what they REALLY do is "monitor the current on all three output lines going to the motor". There is a big difference between "phase" and "line", and people who should know better that lackadaisically conflate the two terms, make it a lot more difficult for those of us who try to keep trying to explain to people why having three hot lines running into a building may make up a three phase service, but having two hot lines running into a building only gives you a single phase service. A phase is not the same thing as a line. On a three phase service, you will have Line A, Line B, and Line C. You will also have Phase A-B, Phase A-C, and phase B-C. A line is a conductor, while a phase is the potential difference between two conductors - huge difference, and in an educational presentation like this, the concise definition of terms is paramount in furthering the understanding of electrical systems to people who come here to learn. All that said, keep up the good work and I hope to check out more content from you in the future!
Thank you so much for taking the time to watch our Drive Basics eLearning Module. We appreciate your feedback and will be sharing your comment with our technical training team.
@@YaskawaAmerica Thank you for your reply. Like I said, I'm not trolling, but I really do think this is an issue that needs to be addressed. I have also commented on an Eaton video where they referenced a "phase to phase" short - which is technically impossible unless you are intentionally conflating "phase" and "line" as being the same thing.
Gracias ingeniería por aportar gran información, y así con un VDF YASKAWUA, realizar los proyectos de mejora continúa, innovación y solución de problemas gracias y mucha suerte y mucho éxito, saludos desde México técnico en mantenimiento electromecanico
Thank you for the video. At 15:08 you said, "Electricity...will follow the path of least resistance". Maybe you should rephrase it to say, "Electricity passes through every path possible even if the resistance is high or low. The amount of current through each resistor will be different."
What kind of Test? Run Test or failure test? For the Run Test you may download your VFD operating manual and read carefully before even touching VFD. It's such a complicated piece of equipment also lethal for huge 3 phase power. For Failure Test you must read Service manual in order to accurately test your VFD.
Thanks for your interest in Yaskawa Training! We do offer four eLearning Modules that focus on troubleshooting. They are eLM.AFD7.11, eLM.AFD7.02, eLM.AFD5.01, eLM.AFD5.02 and can be found on our website at www.yaskawa.com/support-training/training/elearning-curriculum/-/content/_30f87083-5d04-4fbb-a470-e3c78ba85d11_InverterDriveseLearningCurriculum?_yastabstemplate_WAR_yastabstemplateportlet_selectpageRage=undefined&_yastabstemplate_WAR_yastabstemplateportlet_selectprodGrp=undefined&_yastabstemplate_WAR_yastabstemplateportlet_selectprodsubgrp=&_yastabstemplate_WAR_yastabstemplateportlet_selectSubTopic=Troubleshooting%20and%20Maintenance&_yastabstemplate_WAR_yastabstemplateportlet_selectstatus=&_yastabstemplate_WAR_yastabstemplateportlet_selectrole=&_yastabstemplate_WAR_yastabstemplateportlet_selectprodLine=&_yastabstemplate_WAR_yastabstemplateportlet_focus=yes
A link to the first part or playlist of this series would be helpful either in the video description or in the video itself. I don't understand why so many RU-vid channels fail to provide this. Isn't one of your objectives to have more of your videos viewed? The easier you make it for people to find the beginning of a series the more likely they are to jump back to the beginning of the playlist and watch them all. If I have to search, I will see other channels with similar subject lines or keywords and I may end up watching a different channel.
