Thanks for query, Already this video is available in hindi, you can see ,go in playlist and scroll down next video . You can see by click below link also. th-cam.com/video/34DtSSHpofo/w-d-xo.html

Ok, please wait

Thanks for suggestions

Thanks for asking this question.. When you goes for upload that time becomes one block by default,Delete the Block and try to upload again. Please let's try and give feedback Thanks

can you share your whatsApp number

sir i upload program s7 200 , two machine , and i open this program same problem show in my laptop, this POU contains one or more invalid reference to parameterized subroutine

Thanks dear

Sure , please wait 🙏

🙏 Thanks dear

Thanks for message, Sure I will post video related to this .

phase refers to the relationship between voltage and current waveforms in an alternating current (AC) circuit. It can also refer to the number of electrical cycles that happen in a second, which helps determine the frequency of AC power.

Thanks dear

This is related to field current issue , please to be observe field current during load and high speed .That means field weakening ,it is match with motor name plate or not. Please see the parameters of field 44 . If problem not resolve than you can field tunning also . I think problem will be resolve.

thank your replay sir ,

sir can you solve ABB DCS550 drive when i start without load dc motor (90kw, armature 225 A, FIELD 6.78A ) , remote mode and i observe field current taking 10A, and check voltage 375vdc, ,armature load 2.3 ampere motor is not run after few second f541 fault show in bop panel and if i change parameter 9012 not use and 2118 on run local mode motor runt but if increase speed 50 rpm above motor trip

Keep current limit 50% then 100% Keep stand by field 25% ,50%,75% and 100% Keep drive in local mode and operate operating panel locally .Start speed from slow like 10,20,40,50 and increase check to all current is ok or not. If not resolve then please auto tune to motor ,note down before and after 24,43 ,44. Important parameters is 24,43,44,99

Lubrication: Lubricate the bearings and working parts of the mill to reduce friction and improve efficiency. Alignment: Ensure the work rolls are properly aligned. Pressure distribution: Work rolls should distribute pressure evenly across the metal to promote uniform deformation and consistent product quality. Backup rolls: Use backup rolls to minimize the risk of wrinkles, buckles, and other imperfections. Cooling: Use spray nozzles to create a fine mist that rapidly dissipates heat.

th-cam.com/video/xRTkofmUFzg/w-d-xo.htmlsi=hWglsjgTqAcRAPD_ You can see the tension formula and other in this video

Tension= Torque ( output)*2*1000/maximum dia Torque output = total toque * i ( gearbox ratio) Torque= 9550*power (kw)/base speed( rpm)

Thanks dear

Pass line schedule decide by operation ,entry thickness and final thickness decision.Desire reduction by the pass schedule.

Bending is used in a cold rolling mill to control the flatness of the rolled strip, and to adapt to a wider range of incoming product widths and profiles. th-cam.com/video/YA22CPxE8w8/w-d-xo.htmlsi=LbD2-_ehBryMWSi6

@knowledgedevelopmentchanne8720 Thanks sir..

Thanks dear

Ok, please wait

Thanks

Thanks dear

Please check lock clamp leakage ,if cylinder internal leakage in lock cylinder then this type of event happening.

Hello friends , I have no pdf for the question answer but if you have need then you can write down the question answer from my channel video by video. I can provide you but it will late . I will also write down then I will give you. Thanks for questioning and good for your awareness about knowledge.
