ABB VFD Wiring Fixed

We installed some ABB 580 vfd in a chiller plant retrofit. We are retrofitting the plant to Multi Stack chillers from Trane water cooled screws. We changed out the pump skids and converted them to variable speed. The start stop on a ABB vfd with bypass gets a lot of hvac technician tripped up.

Man, I ran into this exact problem last weekend......the wiring diagrams gave me flashbacks. It was my first time with an ABB VFD, but not for the other guys. Got it figured out after finding the second diagram in the manual. You are a great resource.

The new camera is good , seeing you tryna work one handed was kinda weird 👍

[@MG19100]

I'm liking the new camera angle, picture looks really clear too. As someone who did resi for a few years and got into commercial recently your videos have really helped me man. Appreciate all your videos and knowledge!

[@anthonyrivers454]

I love your videos, I started out watching you in trade school while I was doing commercial new construction ductwork constantly wishing I could get into service/industrial work. 4 years later I work for one of the big OEMs service department, I still watch your videos and learn something

[@thanhnguyen-su6bj]

i would like to say thanks for all the tips that you reminded. example put back valves and things back to it place. before customer experience the difficult of call back. i would like to ask of how to improve of schematic, troubleshooting.

[@ruddigger83]

Good drives, don't ever use them with a bypass requirement so that was an interesting with the inputs. The only issue i have is ABB didn't provide any way of copying the programing from the 550's to the 580's.

Very pleasant watching experience. Really enjoyed it!

[@eb3872]

Wow thank you for the knowledge . Keep the videos coming .

[@jimmymurphy6106]

Thanks this video was very helpful for a project I’m working on

[@thesilentonevictor]

Great video tech

[@zjeepgozweeln]

yeah people often get confused by the e-clipse bypass. if used, bacnet comm goes to the bypass unit. if you use hard wire for ss/speed then only the speed reference goes to the actual drive. the ss goes to the bypass. the best is when someone lands comm wires on the drive and then goes in and changes the modbus comm settings between bypass and drive, trying to get comm working. 🤷

Great video like always keep them coming 🫡

[@Drizz322]

The Way video like this should be shot. Keep the head camera rolling. Better perspective in my opinion

[@moonlightacmaintenance3232]

Like the format

[@alecwiley6187]

Liking the new formatting. Easier to hear you and I think your explanations are clarified better when edited this way

[@kevinvillal6169]

This is nice I like it

[@josuerubio8002]

I run into these eclipse bypass drives so much I’ve memorized the controls wiring. The Yaskawas with the bypass are simpler all your IO goes back to the same board.

[@user-dd6eb9bo8r]

I don't have mother board fr SKM chiller after see burning in it ...i restart chiller by connecting. EEV with evd control from carel no problems

[@ericmodernel9205]

OK good job

[@SoutheastHVAC]

What camera mount are you using?

[@Exile1213]

I don’t get how controls contractors cant figure that out. I’ve been in controls for 10 years and 10 years in mechanical service, and it’s so basic. I see this kind of stuff all the time and it’s just blows my mind.

[@zack9912000]

I've seen plenty of control specialists miss this over the years, so I would say not so basic even for people who do them daily

[@EduardoGonzalez-xn8ut]

I’ve seen multiple times where the minimum reference is set at 0hz at the vfd causing the controls not to send a speed reference..

[@halimturqui5007]

Hello, I'm not sure what is the use of the "By pass" on a regular drive ? I know "true" softstarter always have a contactor bypass like on the McQuay you've shown recently on your channel, but a regular drive ? 🤔

[@dennisf580]

in case the drive fails

[@halimturqui5007]

@@dennisf580 thanks 🙌

[@jasonjohnsonHVAC]

Oh buddy i know this site well.

[@haydenpowell1787]

How do you know so much and such a young age

[@GlenS123]

Camera is fine, put it on a tripod behind you, get sea sick with constant motion...

[@eb3872]

Nah , the camera is good we’re it’s at
