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!
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"
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.
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.
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.
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."
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.

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.
I have a question regarding vfd auxiliary filteration and chokes . Why would a choke connected with a phase heat up so much yet the other remaining two ,are found to be extremely cool?
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!
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
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
Very great explanation video, about vfd, how about parameter setting, like carrier frequency, from another video i saw, it can reduce noise of the motor but will increase heat of the motor, can i apply this carrier frequency setting to 24 hours running motor, like motor for AHU or for Chilled water pumps?
Thank you for your interest. There are many advantages and disadvantages to changing the carrier frequency. Please contact please contact our Tech Support team at www.yaskawa.com/support-training or visit or Yaskawa Solution Center solutioncenter.yaskawa.com
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.
I love yaskawa... I'm an electrical power engineer and I just got a job in my field of study and there are yaskawa drivers 1000 series -my question is were I can learn more about the yaskawa 1000 series drivers in details?
Thank you so much for your interest in "Drive Basics." Yes, we do offer classes. For a schedule of Yaskawa Drives and Motion Control product training classes, please use this link: www.yaskawa.com/support-training/training/
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 UA-cam 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.
Thank you so much for your interest in "Drive Basics." Yes, we do offer DC Drives. For more information, please select the nearest service provider in your area: www.yaskawa-global.com/company/profile/global or contact our Technical Support Team for further assistance at www.yaskawa.com/support-training/support.
I wonder why the PWM output is sent direct to the motor and not filtered to produce a sine wave? Is this to save cost since the motor will effectively filter it itself (albeit with more noise), or does it have something to do with keeping the torque maximized even at low frequencies?
Thank you for your interest. Since the AC output is simulated it is recommend to use an oscilloscope (isolated from ground) to simultaneously display the frequency of the PWM output and a voltage comparable to the motor nameplate rating. For further assistance, please contact our Tech Support team at www.yaskawa.com/support-training.
Please contact our Technical Support team to ensure parameters are set and PID adjusted. View their contact info: www.yaskawa.com/web/guest-staging/support-training/support Thank you!
Hi Claudio, Thanks for the comment. Currently, we do not offer VFDs for electric vehicles. Feel free to contact us with any other questions at marcom@yaskawa.com
This video was not intended to consider quantum mechanics, where all paths are possible -- even those through the moon. He did not say it will follow *_only_* the path of least resistance. I suppose if one has been bitten by being in a path of higher resistance, they might be unhappy with the simplified statement. Just because a cabinet is "grounded" does not mean it can't be dangerous.
Thank you for your interest in Drive Basics. To better assist you, please contact our Technical Support Team for further assistance at www.yaskawa.com/support-training/support, Please provide us the model and serial number of your Yaskawa Drive.
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!
I could listen to him all day, except when he starts saying "adam" instead of "atom"
This is priceless all these yrs working with motors and wiring up panels. My new passion thank you for such a clear and concise tutorial.
I thank you
The Best Video i have ever seen explaining the Yaskawa Drives. thanks for you.
The Bob Ross of Yaskawa. Love it
Really great and very clear explanation of VFD drives and it's working principle.
One of the best I have seen so far on the internet. Thanks..
Great! The choice of words and the detailed information.... A perfect video for a beginner to understand VFD.
Oh my what a lesson. I have to repeat again in order to gain everything that has been said. Just amazing
One of the best tutorial on drive basics. Well designed and informative. Thanks for sharing. Keep it up.
If I hadn't seen this module I wouldn't have understood many things concerning VFDs. Good job, I do really appreciate.
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.

Thank you so much for this great video. One of the best content on internet.
Thank you. It helped me a lot for my electrician exam in Canada. the best way to learn.
Glad it helped!
I realy like the way he explained all of his video.. all by heart.
I wish this gentleman was my tutor , extremely engaging !
That's the way sharing knowledge with everyone and u will increase your knowedge more .Thank u Sir
Great. I like how you should how each part looks on the circuit
This is the great video I ever saw. very clearly , smartly explained each and every point regarding drive.
Mr. Koehler, all your videos are too good.
Very carefully selected words. Lot to learn from for starters as well as experienced engineers.
Very good information about VFD's thank you so much YASKAWA and Mr. Steve Koehler.. Expecting more videos from you Mr. Steve.. All the best 👍
Congrats to Yaskawa Team! A special one to the Steve's didatic!
these lesson are so damn good! great teacher, editing, and content! thank you!
A well detailed explanatory video. kudos yaskawa
This guy seems like he's educated, informed, knowledgeable and cool as cucumber. Feel like this is from the 80s early 90s
Superb tutorial, Steve!
really i need more valuable videos like that. thanks yaskawa
Im here because, I am a new sales engineer . Great product training I wish I will execute the same explaination like you godbless

You are correct, those are two of the many important factors that affect VFD design and implementation into various applications.
Since the AC output is simulated, how do you check the output voltage when troubleshooting a motor not running?
Thank you for your interest. Since the AC output is simulated it is recommend to use an oscilloscope (isolated from ground) to simultaneously display the frequency of the PWM output and a voltage comparable to the motor nameplate rating. For further assistance, please contact our Tech Support team at www.yaskawa.com/support-training.
hi there Yaskawa. Is it possible to connect the analogue output of the 1st drive to the analogue input of the 2nd drive for PID control?
Please contact our Technical Support team to ensure parameters are set and PID adjusted. View their contact info: www.yaskawa.com/web/guest-staging/support-training/support Thank you!
does Yaskawa produce also inverters for electric vehicles? (i.e. running from DC coming from batteries and with no need of input AC rectification)
Hi Claudio, Thanks for the comment. Currently, we do not offer VFDs for electric vehicles. Feel free to contact us with any other questions at marcom@yaskawa.com
Thanks you so much , simple and easy to understand
Most common use of vfd is the parameter...how to apply this...
Great video and a nice soothing voice, XD!
I work in the big and small industry in europe,and the vfd yaskawa has no equals on the market.best ever used
