Cheers,

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..👍👍👍
Sir,Thank u so much bottom of my heart,very useful vedio..
The way you take the time to describe it is awsome subcribed!
Great video. Very useful! Thanks for sharing.
Very helpful video, thank you for taking the effort to conduct it in perfect English :)
Thanks :)
Very clear explanation. Thank you!
+Christian Piponides Your welcome!
Excellent explanation bro....
Thanks a lot ...very helpful
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
what is the make & model no. of incremental encoder used in the video?
Thank you. Great tutorial
Thank you :)
sir please make a video on multi axle CNC..
Great job,
But where is second & third video of encoder
(Rpm and direction)
Brother nice explaination.......u r are inspiration.......
Thank you :)
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
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.
great video, thank you, i use your video to teach my class.
mikey mendoza That's a compliment. Thank you !
you are most welcome
Hi dear...
Could u plz tell me.....
Can we use PushPull encoder instead of TTL or HTL
thank you!! helpful video
Your welcome !
🎉🎉🎉🎉🎉🎉🎉 very good explain
Thank you! 😃
Thank You....
Great Rajvir well done keep it up

good job..specially ur hindi lectures...keep doing
+OMER TARIQ thank you :)
you are skilled............I am making my own SCADA and PLC.....
+Sachin Singh Great :) n good luck
Doing great job
Thank you :)
Nice video!
Good evening sir.
Please share Encoder Regarding what is TTL & HTL communication.
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?
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 :)
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
That is not normal. What is your surrounding temperature?
Nice.. tnx..real hero
Thanks for the feedback!
Awesome .......Great great great
+JYOTI verma thanks
would u please demonstrate how to read encoder through S7_300 PLC?
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.
thank you....
Great vid
Now how would I make a bomb?
thank you Sir

verry nice video sir dear sir i request ple explane hindi langauge.
Thanks alot :D

Very good
is encoder pulse and servo motor pulse the same thing?
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
Sir please tell me the encoder is analog or digital input device.
There are both types of encoder - Analog and digital
kindly tell the make & model no. of encoder used in the video
You can see the similar one here: www.ebay.com/itm/ONE-NEW-ES5-02PN8941-Delta-encoder-/182347078040?hash=item2a74bb9998:g:S7IAAOSwo4pYIZ~Z
GREAT
Hello Sir
One video creat a Siemens PLC S7200 smart st20
could you plz tell me how to select encoder
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
thanks rajvir sir. what is 4 fold division
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.
Rajvir Singh thanks sir
thanks you sir i want learn from very basic.would you plz help me
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/
Later I asked Questions.. but not give ans
Where do you have the encoder library in the automation studio 5.2??
Wow
Thank you!
uhm, anyone even looking up "encoder" will know this stuff, was hoping for more but....ok good for the record for newbs...
I looked up "encoder wiring" and did not know this.
is stepper encoder?
What you mean? Are you asking if stepper motor has encoder? Then answer is No! You will only find it in servo motors.
Rajvir Singh okkk
waiting for your reply please
