[@jatinchatterjee2219]

excellent explanation raajvir Bhai,that's the reason I rated ur videos as no.1 in terms of clearing all doubts,clearing all fundamentals of any topic u explained,i really like ur videos bro..👍👍👍

[@georgekerwood9100]

Very helpful video, thank you for taking the effort to conduct it in perfect English :)

[@thegeterrdone]

Thanks :)

[@pramodkumar-in6yv]

Sir,Thank u so much bottom of my heart,very useful vedio..

[@skatewithvanz]

The way you take the time to describe it is awsome subcribed!

[@rexwijesooriya3678]

🎉🎉🎉🎉🎉🎉🎉 very good explain

[@thegeterrdone]

Thank you! 😃

[@hassanlotfy7712]

assume that encoder rotated in direction 1, and channel A gave high then B, then shaft stops in between channel A and B, then it rotates again in same direction 1, B will give first this time, which will be translated in code to direction 2 though the rotation direction did not change, explain?

[@thegeterrdone]

Good question: The Controller which reads the encoder notices the pulses very carefully. According to your situation if A comes and encoder stops. The controller stored the info that A was the last pulse. Now if B cones it knows the direction is same and if A comes again it means the direction is reverse :)

[@mangeshrane4100]

Good evening sir.
Please share Encoder Regarding what is TTL & HTL communication.

[@twitttertsai5228]

Great video. Very useful! Thanks for sharing.

[@jugnu361]

you are skilled............I am making my own SCADA and PLC.....

[@thegeterrdone]

+Sachin Singh Great :) n good luck

[@praveenkumar-np4ry]

Hi sir , How to stop the count value of the encoder exactly to the desired value. With receding the counts more than the kept value

[@AsifShaikh-zd3kf]

Brother nice explaination.......u r are inspiration.......

[@LearnPLCinHindi]

Thank you :)

[@stanleypolanco4887]

regards, i have multiple allen bradley 845T series encoders my question: is it normal to get hot even without operating? I thought it was faulty and bought others but it also gets hot over 40 degrees centigrade without being in operation

[@thegeterrdone]

That is not normal. What is your surrounding temperature?

[@AnwarHossain-lb5eb]

Excellent explanation bro....

[@m.a.kanoje4567]

what is the make & model no. of incremental encoder used in the video?

[@mfaizanmajeed]

Great job,
But where is second & third video of encoder
(Rpm and direction)

[@farrukhbashirxhah7997]

Hi dear...
Could u plz tell me.....
Can we use PushPull encoder instead of TTL or HTL

[@zulqarnainumartariq]

good job..specially ur hindi lectures...keep doing

[@thegeterrdone]

+OMER TARIQ thank you :)

[@VikashKumar-tk3de]

Great Rajvir well done keep it up

[@thegeterrdone]

+Vikash Kumar Your welcome! Find more free/paid tutorials at www.nfiautomation.org. If you want to reach us., please write to [e-mail]

[@94rachaelk]

Thank you so much! How would you know how many ppr you would need. I want to track position of a 7 foot diameter rotating pipe. Would I need a higher resolution because the diameter is so big?? Thanks

[@thegeterrdone]

That depends on the accuracy you need in your system. If you consider 360ppr , this is very less resolution. I would consider you to buy atleast 1024 ppr and using fold fold division you can increase the resolution by 4 which means you will get 1024 x 4 pulses per resolution which is a good resolution.

[@santanumondal6926]

would u please demonstrate how to read encoder through S7_300 PLC?

[@thegeterrdone]

We may do it's video in future. We do not have S7-300 but S7-200 or 1200. I dont know, if that would help you.

[@chrisbeasty]

Very clear explanation. Thank you!

[@NFIAutomation]

+Christian Piponides Your welcome!

[@LvvLvvLvvw]

is encoder pulse and servo motor pulse the same thing?

[@thegeterrdone]

Encoder pulse is the feedback from the encoder and Servo motor pulse might be the input pulse that you are referring. And they both are not same

[@mikeytobago]

great video, thank you, i use your video to teach my class.

[@thegeterrdone]

mikey mendoza That's a compliment. Thank you !

[@mikeytobago]

you are most welcome

[@anirbansasmal4942]

Sir please tell me the encoder is analog or digital input device.

[@thegeterrdone]

There are both types of encoder - Analog and digital

[@palashabid]

Thanks a lot ...very helpful

[@shivprasadbomble8705]

sir please make a video on multi axle CNC..

[@zabjorge01]

Where do you have the encoder library in the automation studio 5.2??

[@krishnakumar-pv1hb]

thank you....

[@tuluong5405]

thank you!! helpful video

[@thegeterrdone]

Your welcome !

[@goldtubsee]

Very good

[@NeerajKumar-wy4lw]

Hello Sir
One video creat a Siemens PLC S7200 smart st20

[@tootoosick18]

Great vid
Now how would I make a bomb?

[@AbhishekV1812]

Nice.. tnx..real hero

[@thegeterrdone]

Thanks for the feedback!

[@m.a.kanoje4567]

kindly tell the make & model no. of encoder used in the video

[@thegeterrdone]

You can see the similar one here: www.ebay.com/itm/ONE-NEW-ES5-02PN8941-Delta-encoder-/182347078040?hash=item2a74bb9998:g:S7IAAOSwo4pYIZ~Z

[@ranjana_official]

Thank you. Great tutorial

[@thegeterrdone]

Thank you :)

[@aubreyroche5080]

Thank You....

[@z1z1985]

Nice video!

[@kavatishashikumar2414]

Later I asked Questions.. but not give ans

[@justinhensley108]

uhm, anyone even looking up "encoder" will know this stuff, was hoping for more but....ok good for the record for newbs...

[@drkmccy]

I looked up "encoder wiring" and did not know this.

[@JYOTIverma-xr3gj]

Awesome .......Great great great

[@thegeterrdone]

+JYOTI verma thanks

[@AsifShaikh-zd3kf]

Doing great job

[@LearnPLCinHindi]

Thank you :)

[@PraveenKumar-yj8iv]

verry nice video sir dear sir i request ple explane hindi langauge.

[@rickyriskyyy]

thanks you sir i want learn from very basic.would you plz help me

[@thegeterrdone]

Dear Arun, to learn from scratch i would recommend you our best selling course -Learn 5 PLC's in a Day available here: nfiautomation.org/courses/learn-plc/

[@VikashKumar-tk3de]

could you plz tell me how to select encoder

[@thegeterrdone]

Well it mostly depends on the range of accuracy you need. For example a digital encoder with 1000 pulses per resolution can give you 4000 pulses per revolution if you use 4 fold division while programming. 4000 pulses for every 360 degree of rotary motion of encoder shaft. You can further relate it to your requirement.
You can also get encoder with 2500 ppr which means 10000 ppr with 4 fold division
Secondly it's your choose to select either incremental or absolute encoder.
Incremental encoder gives relative information whereas absolute gives real time information of encoder position.
Rest you can study more about encoders in Interne t

[@VikashKumar-tk3de]

thanks rajvir sir. what is 4 fold division

[@thegeterrdone]

Vikash Kumar Well if you closely notice the encoder pulses. It give you 2 pulses from A and B phases (also explained in the video) now using 4 fold division method we can read edges of these 2 pulses. So now every pulses has 2 edges - Rising and Falling Edge. So for 2 pulses you get 3 edges which means for every cycle of pulses you have 4 pulses. If you notice the cover page of the video you will notice in the last waveform about 4 pulses. Wing counted on one pulses of Channel A.

GREAT

[@gurpreetkalala3708]

is stepper encoder?

[@thegeterrdone]

What you mean? Are you asking if stepper motor has encoder? Then answer is No! You will only find it in servo motors.

[@gurpreetkalala3708]

Rajvir Singh okkk

[@RosieKTH94]
