really your videos are very helpful for us , Thanks you sir

[@martinbrowne4922]

your videos are unreal and excellent help thanks for sharing.

[@sagi110788]

very nice paji...keep it up

[@alexborisbasilioacha958]

please more videos about vfd, well done Rajvir ..... congratulations.

[@jrprince917]

Great Video

[@kyleblackniak4764]

If I am just using the unit itself to control the motor do I need to use the control wires (other than the input leads to the vfd and motor)?

[@LearnPLCinHindi]

What you mean by 'Unit' here?

[@karthikreddy9170]

Hi sir, How to increase or decrease the frequency by using push buttons

[@thegeterrdone]

Check the course advanced ac drive. I have explained it :)

[@thegeterrdone]

Check the course advanced ac drive. I have explained it :)

[@kathiriya48]

and why in first vfd lecture delta drive directly ac connect?

[@thegeterrdone]

Can you please clarify your question, I did not understand what you are asking ?

[@kathiriya48]

Your delta vfd video lesson you use directly ac source.why not convert ac to dc and then ac?

[@thegeterrdone]

+Pankaj Kathiriya that's done by the drive itself ! You just need to connect AC source to your drive !

[@kathiriya48]

+Rajvir Singh (NFI Automation) thanks

[@kathiriya48]

why ac convert to dc and dc convert to ac in vfd input.why not directly ac supply give?

[@thegeterrdone]

This is because we need to change the frequency of the output signal! So we have to convert AC to DC and then create variable AC frequency signal! Because it's difficult to convert AC to AC wrt to frequency Hope this make sense !

[@kathiriya48]

Why not use Cycloconveter to convert ac to ac

[@thegeterrdone]

+Pankaj Kathiriya VFD basically has step up and step down cyclic inverter inside it with intelligent control system of frequency and current

[@delangovan8289]

can i get PowerFlex 70 Adjustable Frequency AC Drive tutorials?

[@thegeterrdone]

Sorry we do not have that specifically, but i believe it wont differ much from Powerflex 40M

[@possibleautomationcontrols6248]

How PLC Communicate to VFD Which Parameters we will use? We use Delta PLC with this VFD Give me the guidance about this

[@thegeterrdone]

+POSSIBLE Automation & Control System If you are asking for MODBUS communication, please watch our video on PLC & VFD MODBUS, but that one is with Delta PLC- Delta VFD. I have not explored Delta PLC and AB MODBUS. But if you are asking for hardwire connection then it's pretty easy, let me know what you want to achieve.

Good afternoon , I'm with the inverter power flex 70 , when I turn appears: Initializing ... Error : Hardware Invalid Port Id DPI Port 0 Please , I thank all the help . Thank U.

[@thegeterrdone]

Please try to reset the parameters! and try again

[@tomealbuquerque826]

Good morning , I can not touch anything , no ihm button responds . If you can help me , thank you. Thank U.

[@thegeterrdone]

Tome Albuquerque Then i cant help you in that case. You need to reset the drive. Check out the manual for troubleshooting techniques please.

[@rohanghosalkar8120]

I had used 4-20 MA as an speed reference source in 4m series vfd of 7.5 kw...My motor has 2800 rpm speed...so if i select 2800 Rpm from my hmi which is of schineder ..the frequency coming on vfd display is only 32 hz ..which has to come 50 hz..so plz tell wch paramarer has to set for this case....awating for ur rply sir..

[@thegeterrdone]

Did you calibrate your current to speed conversion properly? That you can crosscheck..

[@kathiriya48]

plz upload yaskawa and L&t drive video

[@sampetrosyan5334]

good info,, thanks

[@arieljulve1745]

HI Mr. Singh, how are you?..Hopefully, I can introduce you more PLC student next month...Warm regards from Riyadh

[@thegeterrdone]

hii Ariel ! ;) ..thanks man! ^_^ Warm regards from NFI, India!

[@wasimansari-rt5ik]

Plz increase volume

[@bhavesh2467]

Hi Mr. razvir, I am very happy that what I was lloking for long time I got it from you. I mean I want to learn programming & wiring control for AB vfd power flex40, 70 model. I am facing lot of difficulty while troubleshooting in food plant. can you help me out with this by providing more video guidelines as you shown in brief. Right now I want to know that how can I increase freq. of drive more than 100hz. powerflex 40 name plate says max freq. is 0-400hz. but when with keypad potentiometer I cannot increase more than 100hz. why? how to change this frq. of drive to increase my conveyor speed? pl. help me out to improve my knowledge about vfd set up.

[@naeemakram6797]

Sir please make videos in Urdu or Punjabi

[@thegeterrdone]

+Naeem Akram I have already made a new channel on Hindi- check learnplcinhindi In KZbin

[@jonathanemmanuel1960]

Dude we also want to learn. We prefer English please
