- Its concept and explanation of VFD DC bus regulation and Dynamic braking.how vfd regulates DC bus voltage,how to save REGENERATION energy,vfd dc bus parameters,.what is dbr,what is dbu,what is dynamic braking,what is Dynamic braking unit,what is Dynamic braking resistor.
Good Sujetion 👍
Nice abd helpful video.
Thnx dear boss.
Very nice 👌
Best explanation upto know
Thank u very much. You explained very well.. its easy to understand. Got solution for my current problems happening for extruder machine
Rajendra
Excellant. Thanks..
🙏 useful info sir
Your explaning method is very good ....please upload such videos of industrial Automation.....I weating for your next video.
i will keep uploading. thanks for watching keep in touch..

VFD তে কেন Overvoltage fault আসে এবং তার কি সমাধান তা জানতে হলে নিচের ভিডিওটি দেখতে পারেন

Thank you very much sir....
nice from bangladesh
Thanx for good knowledge on breaking resistance,plz make a video on how calculation DBR valve According to motor KW.
👍👍
You explained really well, good work, i subscribed your channel
Thank you so much for watching and subscribing my channel.. please share with your friends..
Nice sir ji
Nice sir g
Thank-you so much brother for always supporting my channel.stay connected

Sir please make a video on how to calculate DBR value
Sir..Industrial Weigh feeder ka upar main ek video banaye...jaise..its wiring to its controller , principle and wiring to its drive..etc etc..pura detail main..
Aur..regerative braking video thoda jaldi banaye..sir..
Sir, vfd repairing course practical level per kahaa kar sakte he.
Sir can you please tell me what is booksize in Siemens s120
Sir please make video on PID controller.
Sir muje flux control method and field and torque control method explain Karo or o video kidar hai
Sir pwm controller ke one, three and asynchronous pluse mode technic ke bare me video btaye
sir hamary pass 110 kw ki moter lagi hai blower per aur us motor k dc bus voltage aa rahy hoty hain vfd per 490 running k doran kiya yeh voltage thek hain ya hamain iss per dbr laga lini chahiy
This is under voltage condition so DBR will not help.if drive is not getting tripp on any fault this is acceptable.do not connect DBR.
@@aforautomation sir ager hum iss blower per 110kw se choti moter laga dain aur vfd k sath DBR laga lain tu kiya aysa ho sakta hai
Hello respected sir I want to get online training about DC Drive +SCR +drive control wiring+Power wiring...
Do you have any mechanism for this????
Dbr used at DC bus still tripping on overvoltage ..what can be done be more.
use regeneration unit which will convert braking energy into 3 phase supply which will save energy too.

Sir moter ke bare mai btao moter roter ko kaise ghumata hai
okay i will make sure.. keep in touch and thanks for watching.
Hi sir I have CIMR,G7A2015 PLEASE TELL ME DC VOLTAGE HOW MANY INPUT.
hi sir
please help me.
Omron vfd 3G3MV-A4055 ke lye brake resistor ki value kia use karoon. 4 kW ki motor crain pe use ki hay aor brake resister ka error aata hy please tell me it's value
what is value of resistance you are using right now?
mH ?
Current rating?
have to set set dynamic braking parameters correctly?
what is fault code when drive trip trip?
How to find resistance value for that
There are some formula which can be used but they are based on inrtia calculation which is very complicated so I suggest yo use resistance value as per recommended by Drive manufacturers/user manual

Bhai... Resistance box kiu lagate h drive me
jab dc bus ka voltage badhta hai to usko dropp karne k liye resistance lagate hai jisko dynamic braking resistor kehte hain aur dc bus aur resistance k beech me dynamic braking unit lagate hai ya ye drive k andar bhi rahta hai.
Thanks... But kya ye resistance sirf AC drive me lagega kya
Sound kaha hain
Sir ap ny kaha k DC input Wala inverter Alag sy order krna prdta Hy jb k aisa bilkul nhi hy.q k ap AC waly terminal main hi DC b Dy skty hain q k aagy convertor lga hota hy or oska kaam hi DC bnana Hy isi liye jb ap osko DC hi Dy dain gy to wo diods automatically osko accept kr lain gy.
Theory or practical main faraq hota hy so please 🙏 get a deep experience first to deliver the children.
Dear Mohsin Most of the AC input powered Drives use ac mains supply to generate Control voltage,fan supply,internal power supplies etc,and in DC powered Drives use all dc source for all above purposes.
it means if you wish to use DC input please mention it during ordering,
and few drives are designed in such a way that you can use them on any voltage eaither AC or DC. but this also you have to care during ordering
