Program a Micro820 to Control a Powerflex 525 with a UDFB

In this lesson we show you how to setup a User Defined Function Block (UDFB) in an Allen Bradley Micro820 PLC to control a Powerflex 525 drive using Rockwell Automation's Connected Components Workbench software.

What you do for us techs is absolutely incredible. Thank you so much for what you give back to the industry. I appreciate it .

Hola Tim, no se si sabes español, pero te queria agradecer en mostrarnos de manera practica estas funciones, que a manera de critica, AB no facilita para los usuarios aprendices o demora mucho el averiguar y terminamos encontrando ayuda de la comunidad en redes sociales, miro mucho tus videos y te felicito por sincera ayuda. Un fuerte abrazo !

I HAVE BEEN FOLLOWING YOUR VIDEOS SINCE 6 MONTHS

Thanks very much for this helpful video! I'm from Brazil, thanks

Hi Tim, I watched the video on your web site and just to let you know I could not "like" the video on that site but could come over to YouTube and have all the normal available options here. Thanks again for another great video.

This video is exactly what I needed for my little training setup.

Thanks mate!

Thanks Tim! How many PF525s can be supported on a micro 850 PLC using this method? Can it support 8 to 10? I was able to complete a project using this method using 2 drives and an HMI. Just wondering what is the limit on the Micro 850.

Did you ever create a next video to this one? Demonstrating how to set variable tags to control the start and stop and speed reference?

[blessing]

I like your lessons, do you guys got full micro800 programming tutorial that i can register or download as a full package?

Ola parabens pelo trabalho Aprendo muito com você, sou do Brasil e acompanha seu trabalho Sucesso

Thanks very much for this helpful video!

Question about the enable bit you're using (PF_Enable_UDFB): Is it standard to enable the UDFB only when you want to use it (i.e., to read/write values), or can it be placed at the beginning of the rung (i.e., FBEN is always true)?

Hey Tim, Can this Function block be used to both jog forward and reverse, as I only see jog? If so do you have a link to a video that shows it or could you make one if one doesn't exist? Thanks for all your videos.

[estebanjoaquinalvarezm]

Thanks you for the video! It's very usefull. You have a new suscriber! Can you make a video explain how to connect to the Excel?

Hi Tim,
I'm having all sorts of trouble sourcing single phase 240v input 525 drives. Everyone seems to be sold out of the 0.75kw and 0.4kw versions (I assume you're running those on your trainers?). I'm getting told 20 weeks wait here in Australia. Can you suggest a US distributor? Cheers!

[douglasburnum]

I would say when I used this UDFB for a project of mine, I could not get it to extract the correct fault code for a 525 drive. I had to use my Tech-Connect and work alongside an A-B engineer who altered the A-B UDFB to work properly and report the correct Fault Code. I'm not sure if A-B has ever addressed this from the UDFB they freely distribute.

[TheLRBrown]

Great video. Very helpful. Is it possible to use this UDFB and MSG instructions if we want to access more parameters than those available in the UDFB? Or is it one or the other? I want to create a position move and the parameters needed are not in this UDFB

[cleitonmatiasdonascimento]

good night Tim What is the maximum number of powerflex 525 I can control with a micro850.

[PROFEDGE]

What version are you using? Version 22 doesn't have the trending charts any more..at least i can't it anywhere.

[CrypticCabal]

I know this is an old video, but the link seems outdated. Trying to setup a test bench to play with the drive, and can’t seem to find any resources to make the 850 communicate. If there’s something updated or additional resources, any help would be greatly appreciated.

[francisco]

Hi Tim. Any chance that you have a video where you do the exact same thing except you use the Modbus UDFB and communicate via RS485 to the powerflex 520 series drive using the 2080-SERIALISOL plugin module?
