Awesome explanation man. Just fascinatingđđđ
Share more videos... Nice sir. All videos r use full
Thanks sir...same concept we are using in silicon coating process ans vinyl coating process
Which parameter is maintained constant in vector control method (explain using speed, Torque and power relationship)?
Thank you saheb.... 9 saal ka doubt 9 minutes me clear kar diye aapne
Always Welcome.
Sir the videos are best .. thanks sir it helps a lot for beginners like us . Keep teaching sir
welcome brother, its my pleasure to share knowledge which i have.. thanks for watching, keep in touch...
thanks sir very nice explation. but can we get also a vedio of programing plc with delta and see how control other vfd with torque ?
Best Video Sir! đđđđđ
Great content
Nice explanation sirji TQ
Hello sir can you please make a video how to control wiring between two different make ac drive one Unwinder and second drive is rewinder tension mode
Nice video sir
Is the speed reference which we gives is master br speed reference
Sir same concept applicable in dc drives??
What changes happen in motor and drive sir when drive run in any one of this mode?
Sir please make one video on Emg make recoiller edge guide system.reference measure camera
It is a humble request to you sir please make video on CGL line with individual section with modes.
Thank you sir pls make a video on cgl line
Sir C2000 delta me kya dalna padega
Torque mode k liye
Too good ..thanks sir ji
thanks for watching keep in touch and keep sharing
I have seen your videos on master /slave configuration. Many doubts are cleared as I work in steel rolling Industry.
I want to know that how process line master motor is selected or make video on this topic. Please reply
i am getting knowledge on selection process of master and slave.will must make video in future
very nicely expained.
Thanks for watching keep in touch.
Sir Thanks for this information
Sir ye agr ager ap practicaly bta dyn to main is main phasa hua hon please kaise parameters k through perna ya manual se video dikha kr bta dy
Siemens Sinamics G120 drive Torque parameter P 1503
Sir first of all thank you very much for your videos.Now I work in galvanising line.Can you make a video on speed and tension control of different parts of the line.Such as tension control in entry section with accumulator...
Or tension and speed control in different bridle section.
Please help.
Welcome to my channel.i will make video very soon keep in touch.
Sir can you please explain internal torque reference .
Can u guide me which VFD is best suited for 20hp induction motor 3-phase reciprocating air compressor??
Powrflex 755 (Allen Bradley)
Sir can you please make a video on that how I can I make a program in plc to make drive run according to these parameters.
yes i am going to make plc programming video as well in future keep in touch.. thanks for watching
Sir please make video about EOT crane drive & application
I just wanted to know in case there is Strip breakage or skidding we observed a tension drop at Uncoiler as speed ref matches with speed actual but y tension drop as we are giving Torque ref and drive is in max torque mode. So y speed matching create tension drop.
Tension is applied on strip if strip breaks then tension on strip will be zero, we give a speed ref to avoid free run of motor when strip break/slip..
@@aforautomation But we are not Measuring any physical tension on strip...it is calculated from torque and torque ref is there
Yes torque reference is there but tension is calculated by actual torque, is sheet breaks drive will not achieve its torque reference and keeps rotating at higher speed in reverse direction to achieve the required torque.
@@aforautomation But in our case I seen that POR speed Actual is always greater than Speed ref..When there is skidding we observed sudden tension drop. Speed actual reduced to Speed ref..pls explain once...
@@aforautomation sir then in that case please explain the situation
If strip breaks during running line then as you said we are giving negative saturation reference ( speed limit ) to uncoiler to stop rotation in reverse direction *so during sudden breakage *CAN WE SET ZERO SPEED LIMIT TO UNCOILER TO STOP SUDDENLY* .... kyuki Strip break hone ke baad recoiler bhi suddenly stop ho jata hai !!!
Aur agar mai galat hu to please us process ko samajha dijiye đđđ
Thank you â€ïž
Sir jo unwinder winder aur bridle ka application hai wo constant power load ka hai??
yes you are right.
Good job sir bahut achha laga video or 1bat hai sir uncoiler reverse direction mai tention or turq hota hai speed vi reverse mai chalta hai sir forward mai kuch vi takat nahi lagata hai Es mai halka confuse huwa hu mai sirâ„ïžđâ„ïž
Sir ABB ACS 800 jo Ac drive ha uska parameter upor ak video bania taki pata Chala kaisa DI AI satting hota ha
Plz make video on PLC communication and how to assign input and output in FBD PLC
very soon i am going to start PLC programming series.. thanks for watching keep in touch.
Dear sir...if I want to run severel motor in the same direction with some tension and analog input as load cell. What will be the system..please make a video of load cell for tension as well as sychronizing
You will have to use master slave logic,one motor will be master and others have to follow it. please see my master slave video, if you have plc then its very easy.
give torque reference to master drive and actual torque of master motor should be limit to other motors, actual torque of master motor is to be send to slave motors as torque limit (please see positive and negative limit parameter)
@@aforautomation Thanks for your reply Sir. I am greatful to you..
Nice video sir but i have some doubts i.e If paper sheet will break between a master and slave motor then what will be the effect on slave which is taking actual speed reference from master.Similarily what will be the effect if that slave is taking actual torque refence from maser?
very good question
if paper breaks between master and slave and both are running in speed mode then speed will increase very fast and drive will increase its current upto current limit value which we set in drive. if both motor are running in Torque mode then speed will be very high and drive may trip on over-speed fault it will reach upto max speed set value in drive.
A For Automation Thank u sir..I got my answer....
Sir CGL line k overview pe video banao with mode in detail
How to make load sharing scheme of ac VFD
WE HAVE A POWER FLEX 700 DRIVE FOR RUNNING A KILN . WHEN PLANT STOPS DUE TO POWER FAILURE AND WHEN WE START AFTER RESUMING POWER , IT FAILS TO RUN , TRIPS ON MOTOR STALLED ALARM , WE TRIED TO INCREASE TORQUE SETTING BUT IT STILL TRIPPING ON MOTOR STALLED . THEN WE HAVE TO RUN INCHING DRIVE TO EMPTY THE KILN AND THEN ONLY MAIN DRIVE WILL START NORMALLY ( AND IT TAKES AT LEAST 30 MINUTES) BY INCHING DRIVE . WHAT SHOULD WE DO ?? SIR CAN YOU HELP ON THIS ISSUE ..
Before stall fault it should tripp on Under voltage fault when power fails .check input supply voltage parameters and increase if required.or disable stall fault
Dear Sir, How we control VFD by analog signal as example Load cell for tension and synchronizing motor
you will have t use pid for it, like you will set some tension and feedback will come from load cell so correction signal will be calculated by pid and you will have to send this as torque reference to Drive.and keep drive in torque control mode.
for sycronization you will have to chech speed of motor and add multiplying factor in speed reference in plc program.
Its too good, thanku sr, Please can u explain how can we provide - ve torqe to the motor from vfd
by giving negative torque and speed reference.
the torque in reverse direction is called negative torque..
@@aforautomation sometimes i experienced when the drive running in FWd direction, Drive display show actual value of torque in - ve, why this is so
Agr m vfd s 5 frequency p chalaau motor to wo kitna torque degi jb k m chaahta hu k wo full torque de jo k uska rated torque h
agar aap low speed pe full torque chahte hain to drive ko torque reference dena hoga aur uska control mode parameter ko torque control set karna hoga, ek potentiometer laga k aap kar sakte ho
Sir torque refrence kesy den gy
I have doubt ..how can I contact yu
Sir ise tarhe se hame drive system me saport karte rahe.
I have faced one issue which is consistent, it is that in paper machine I have observed that paper gets loose in two dryers (post dryer section). But thereâs no change in the actual MPM of the dryer section but still the paper gets loose. What could be the reason behind such issue.?
We call this issue as draw variation in paper machine.
have you changed any encoder or roll ? it may be because of roll dia mismatch between physical dia and dia in plc programming..or encoder PPR mismatch in drive and actual ppr of Encoder
A For Automation we havenât changed any roll and also we do not have encorder in our system. Itâs running on open loop in master slave configuration. We have all abb Make ACS850 drives
you should check mpm of roll physically by hand tachometer it should match with system MPM if there is a difference it should be corrected..
A For Automation already done that MPM is matching. This problem is not an constant problem, the problem comes at anytime for few seconds and then it gets corrected as correct the draw on control desk however we are not to find any fault.
there may be some slippage on next roll which is next to dryer unit or it may be because of paper material hardness variation.
you can create a graph in plc program to observe the process like motor speed and torque etc.. parameters
Do you have this in English?
Sir main coating line mein kaam karta hu main dekha hai ki unwinder mein Jaise Jaise wraps kam hote hai wise uska ta torque bhi kamm hota hai but torque mode mein chalne pe Aisha nahi hona chahiye. Winder mein wrap badhne k saath torque bhi badhta hai
Kyuki Unwinder me wrap kam hota hai to uska inertia bhi kam hota jata hai isliye kam torque me hi tension mil jata hai.
@@aforautomation sir but torque mode mein torque constant hona chahiye naa sir torque to constant nii Raha uncoiler mein.
@@nageshpandey5333 Unwinder ka kaam hai Tension ko constant rakhna uske liye plc usko torque reference deta hai jisko wo maintain karta hai
Jaise jaise diameter kam hota hai vaise vaise torque reference ko bhi vary karna padta hai kyuki Unwinder ki speed badh rahi ha
@@aforautomation thanks sir
Sir ji Siemens ka kya parameters hai
Sir dtc control video pls
sir please tell me formula of toque calculation in terms of bridle dia and formula for line speed calculation
Line speed (MPM)=Pi D N /GR
D is roll dia,N is motor RPM
I will make video on this topic
thank u Sir I am waiting for that video
Dear sir, please answer my question.
1) How to check speed or torque mode in Siemens drive? In which parameters?
2) Can we operate a drive of bridle in torque mode and POR/Recoiler drive in speed mode?
in sinemics G120 CU 250S parameter no P108 index number 18 bit no 2 ko activate karna padta hai by using Starter software.
yes we can use torque mode in bridles and if por/recoiler is maintaining tension then we have to run them in torque control mode
please let me know which drive you are using
Dear sir, I am using drive sinamic s120 CU320DP/PN and CU240DP/PN
@@anuragtyagi6602 for s120 parameter no is p1501[0]. Please check ... we are also using s120 drive and i think we can help each other technically .. pl contact me on 9810348214
SO MANY MOTORS IN ONE PROCESS HOW IT WILL WORK TO UNDERSTAND DIFFICULT .
two different make vfd use on tension control applications
if use communication through PLC both drive should be compatible with same network otherwise you will have to use different network interface unit at plc side.
second option is to run drive through analogue input.
Nice sir g
thanks for always supporting my channel Hukam singh ..
keep in touch....
Re winder me encoder lagana jaruri hoga ya nahi ?
yes encoder is must for re winder.direct torque control drives can run without encoder too but if you are controlling tension then encoder should be used.
@@aforautomation wich ac drive is used in winder torque control without encoder feedback .
Now I am currently use yaskawa A1000 with pg encoder
Aap parameter bhi bataye bahoot achcha samajh me aayega
sure brother. thank you for watching and kind suggestion..
Torque & speed dono mode pe chlana hai
sir agr mh torque mode mh chala raha hu to for example mh 30% torque dediya input ... toh motor kis speed pe ghumegi please tell this is big confusion for me
Torque mode me motor ki speed load k hisab se rahti hai agar load jyada hai to speed zero bhi ho sakti hai aur agar load kam hai to speed full speed tak bhi ja sakti hai.actuly aisa koi fix rule nahi hai ki kitne torque pe kitni speed hogi.drive jab torque mode me chalta hai to speed ko saturation point maan k chalta hai.actual speed only max speed limit se kam honi chahiye.aur jaise ki apne kaha 30%torue ref diya to actual feedback ko 30%lane k liye wo speed ko +/-100% tak le ja sakta hai.
@@aforautomation drive apne ap leke jati h speed ya vo bhi write krani hoti h sir
@@aforautomation and agr uncoiler torque mh hai nd briddle spped mode mh toh agr uncoiler ki speed upr niche hui relative to briddle to sir loop ni bnega?
sir btado
Speed drive apne aap leke jati hai
Sir bridle kaise tourq shere karenge
Master bridle ka actual torque plc me jayega plc se scaling karke other drive ko reference jayega
