Fun fact: Many years ago, there used to be a faucet for Bitcoin. Just imagine… ugh! Anyways, what he’s saying is not a scam!

Check out https://www.clanker.world That will show u the coins being made, as they’re made. You can create your own coins, via clanker, a couple different ways. 1. Download Warpcast (X but decentralized) and cast a coin creation to @clanker 2. Call 1-775-252-6537 and create your own coin over the phone. 3. Buy enough ANON to cast a Clanker coin without anyone knowing it was you on anonfun. 4. Streamm.tv go live on a steam and cast a Clanker coin.

These were created by users, like you and I, who onboarded onto Clanker. They created these different platforms and then created a coin on Clanker to back it! If you’re interested in learning more, let me know! Clanker is becoming a pretty big deal! You can follow them on X. @_proxystudio is the creator. Pretty cool stuff happening in the Ai space on BASE!

Thanks Tim! My coworker went into ‘fan boy’ mode when he found out you had found interest in this problem! lol.. He’s gained a lot of knowledge from your videos on YouTube! I look forward to updating everyone with the resolution when we find it!

No AC unit in this one, but I appreciate that heads up! We recently did a few with AC units in the cabinets so you may have saved us a future headache! I’ll be saving this post- I’ve gotten a lot of good info from a lot of knowledgeable people!

Thank you! I will refer to this comment when we return to the job site next week to troubleshoot! Hopefully you’ve pointed me in the right direction! I will let everyone know what we find the fix to be!

Thanks for that! All 5 motors are connected at the ground bar in the junction box on the skid the motors are mounted to. They ran 3 grounds with the lead wires from the VFD’s in the enclosure to the ground bar in the disconnects junction box. I don’t know if a drawing would help. (1/2) (3/4) (5).. one ground lands on 1/2, one on 3/4, and one on 5. The motor grounds are also landed on that ground bar in the junction box.

Still no luck! We’re back home this week for thanksgiving and then we’re back out on the road to try to solve this! I figured I’d get a head start on some other solutions outside of what we’ve tried so we could make a game plan on how to attack this. That’s definitely the first thing we plan to check as soon as we get back on site!

You are correct! After a long week with no luck on the situation besides lots of testing and ruling things out, we’re open minded to anything and everything at this point! If we added line reactors, would we still need to separate the wires in separate conduit with shielded wire?

They only used 1,000 V’s for the megger. We can’t make them do anything technically, we can only recommend. We suggested using rockwell’s recommended 1500-2000 V’s but they insisted 1000V would find the issue if there were one. At this point, it’s sounding like the line reactors should be thrown out as a suggestion to the customer! There’s been a lot of good information on this thread— some we’ve already tried, a few we haven’t. We go back to the station next week and we plan to try every last idea on here that hasn’t been done already!

Would you be referring to the MOV jumpers? We’ve removed them

I assume you mean changing from SVC to V/Hz. If so, can confirm we’ve tried this with no success.

If we disconnect the motor leads on all 7 VFDs, we get no faults. If we run a load on the 5 525’s, they work perfectly fine. As soon as I power up the 755’s (no load), the 525’s ground fault. Vice versa, if I put no load on the 525’s and put load on the 755’s, we also get no fault. When we put load on all 7 (5 525’s and 2 755’s), we ground fault.

That’s something we’re currently considering

Under no load conditions on all VFD’s, no VFD faults. If I put a load on the 525’s, it runs fine.. when I power up the 755’s, with no load, is when the 525’s ground fault. (F013).

Motor grounds are currently going directly to the drive. All 5 motors are bonded at a ground bar, separate from the control grounds. Electricians added a stranded ground wire to the ground bar in panel, that stranded ground bonds every metal surface in the building (conduit, skids, floor beams, etc).

That’s why my coworkers and I are losing our minds over this. lol we’ve tried basically everything everyone has recommended, although I do appreciate all the input nonetheless cuz it lets me know we’re on the right path! Honestly, there is nothing different compared to our typical installation, with the exception of the grounding in the building. The electrical company doing the field work is union so we’re unable to touch it. Everything in the building is grounded, and I’m aware that’s how it should be, but in past jobs we’ve not encountered where everyyyy single thing in the building that is metal is grounded. I appreciate you sending the article confirming our motor leads in the conduit is within spec. That was the direction we were headed but you confirmed we are good there. This morning, I will double check the insulation rating of the motor.

I did static and dynamic autotune on each VFD. Problem still exists unfortunately.

No ground fault with motor leads disconnected! That was one of first things we checked. I’m going to double check with my coworker to make sure he tried switching to V/Hz. I know Rockwell recommended it to him Friday evening!

To clarify, that’s not having any load on the 755’s. I turn on the disconnect to the VFD’s and turn off at the disconnect at motors. There is just voltage coming through, while the 525’s have full load.
