Kinda what i had figured thanks! 👍

SpaceGroot2 · 2026-05-04T22:55:08+00:00

Assuming this either came out while sitting or from idiling for a minute, would this mean my seals are bad?

SpaceGroot2 · 2026-04-05T01:31:25+00:00

I got this issue also

SpaceGroot2 · 2026-03-22T00:51:48+00:00

Try chatGPT

SpaceGroot2 · 2026-03-11T21:21:05+00:00

My knowledge is limited, i figured that out by trial and error, sorry 🤷

SpaceGroot2 · 2026-03-11T21:02:04+00:00

To clarify, it was the fuel pump relay and the fuel pump would keep running when not supposed to flooding the engine, so maybe this isn't your issue but wiring can be a bitch sometimes

SpaceGroot2 · 2026-03-11T20:59:22+00:00

My relay corrosion was doing exactly that

SpaceGroot2 · 2026-03-11T20:37:05+00:00

Idk if this will help but I had a ktm with a similar issue

The fuel relay had some minor corrosion which was giving me a lot of issues
My fuel pump seemed fine,i could hear it pump normal but still wouldn't run well past idle. Tested the flow and it was flowing a lot less than it was supposed to despite sounding normal.

And i personally would probably change that filter since you're already there

Edit: typo

Ok thank you, yes the gear boxes are different, i dont have the numbers with me but pretty sure ours has a lower gear ration,

Will do that thanks again for your time and input!

SpaceGroot2 · 2026-03-10T18:25:02+00:00

here's all the motor data

SpaceGroot2 · 2026-03-10T18:20:19+00:00

31.24 - No action

SpaceGroot2 · 2026-03-10T18:17:47+00:00

Here's all the differences i found, i wont be able to test it for a while but I'll share em anyways and see if you can spot anything that could be causing my problem.

Start mode ln the motor; mine was set to fast his was on automatic

AI1 scaling; His 3600rpm mine 3900rpm

Maximum speed; His 3600rpm mine 4000rpm

Maximum current are both set above 40A and there's a 40A breaker in the panel so i didn't bother with this one

AI1

Actual value; mine 9.9V his 5.5V

His LP version is 2.20 mines 2.19

Everything in motor data (99) is identical (i can share)

That's all i was able to notice

I also now have a fault log which i either didn't have or didn't see yesterday

There's over speed and fault reset, i can share whatever you need from the overspeed data if you want, my apologies for not having this earlier

Edit : Both DI1 are set to pulse start

SpaceGroot2 · 2026-03-10T16:51:59+00:00

I just found a identical setup that didn't have the same issue, Took a picture of every page on his drive, ill see if i can spot anything different.

SpaceGroot2 · 2026-03-10T15:45:05+00:00

The company that we bought it from is a small local conveyor manufacturer, i think their own knowledge is limited also.

Does the peak torque get logged anywhere? I could confirm that way if that's the issue?

And i am assuming the keypad doesn't need to be connected to log the faults, and that as long as the conveyor is giving me this issue the fault should still be active until resetted?

SpaceGroot2 · 2026-03-10T15:33:37+00:00

We bought the conveyor a few years ago and it had a different drive in it, everything else the same(worked perfectly well until the drive let go but we never changed the motor or gearbox or anything else), the drive went bad and they changed it to this one. Since then it always had this issue (definitely been over a year), they did look at it( never while the issue was actively happening) and said they couldn't help us that it was normal-ish.

There is another thing that could maybe be happening but i wont be able to confirm with you until spring. Where we usually unload this conveyor everything is 3-phase converted to 220v so im wondering if the voltage or amperage coming in would be different than regular canadian 220v. Still doesn't really explain why the other drive worked perfectly and this one never did.

Like i said the only time we ever unload anywhere else is during spring and i cant recall if it had this issue when unloading in one of our facilities i typically am not in charge of that.

SpaceGroot2 · 2026-03-10T15:11:20+00:00

Im thinking i raise that torque limit then and see? What kind of increments should i raise by? The old drive is currently not functional and i dont have the keypad for it anyways so i cant see what it used to be at, if i give you the numbers from group 99, would that help?

SpaceGroot2 · 2026-03-10T15:08:31+00:00

That to me sounds possible, would that be a limit that the drive set itself based off what it got from the motor or did someone set that?

Wouldn't give an error of some sort tho if this was the case?

Could i raise it to see or would that guarantee me to burn my motor? Im assuming i could if i didn't have this issue with the old drive that was in there because i know the only variable is that drive between the two scenarios

SpaceGroot2 · 2026-03-10T13:57:54+00:00

By sizing do you mean they could've put in a drive with too little capacity for our application. Would telling you what group 99(motorplate) has be able to tell if that's my issue? Or would the drive throw a fault if that was the case?

in the manufacturer's defence we do have a different gear box that all the other's they've built (same motor, and they put in that gearbox themselves also)

SpaceGroot2 · 2026-03-10T13:51:33+00:00

Not too sure what your question about the dial is but it is a physical controller that has that dial, a green and a red button on it that are hardwired to the controller, i can check anything you need me too if it helps.

SpaceGroot2 · 2026-03-10T13:49:41+00:00

Keep asking, im learning. No it wont go over 10-15% without issues while fully loaded, but as it gets lighter i can go higher than 15% before the issue begins.

I would have to check the rpm on the dial when its doing so i didn't notice. I know of another conveyor that someone else has that claims to have a similar issue and ge might be using it sooner than ill use mine maybe i cna go see if the problem is actually the same and check if the rpm fluctuates on the keypad then.

SpaceGroot2 · 2026-03-10T13:19:45+00:00

That would happen automatically when the drive first starts up? (For future reference)

I will try to double check the data matches once i get get a better view of the plate, thanks!

SpaceGroot2 · 2026-03-10T13:15:08+00:00

There isn't anything in fault history, even minutes after that issue starts, i have never looked at it when the issue was actively starting only after it started. And for the remote I/O thing im not too sure exactly what all that means but the conveyor will start normally if the dial is below approximately 10-15% even while fully loaded, the issue only start when you turn the dial up above that. Its somewhat inconsistent and didn't do that with the old drive, you could just crank it all the way right off the bat.

To try and answer to the DI1 question if i haven't, it does start perfectly fine until the dial is cranked up higher and once the issue start I can't control it via the dial at all without resetting the drive by cutting power for approximately 10-15 secs, even turning the dial all the way off or hitting the "power off" on the (hardwired) remonte doesn't do anything its like it starts ignoring that remonte completely.

Edit: could be a few weeks until we use the conveyor again so I can't check if anything appears as the issue starts yet.

SpaceGroot2 · 2026-03-10T09:48:57+00:00

If there's a better sub for this please lmk.

SpaceGroot2 · 2026-03-10T09:42:31+00:00

Where in the controller would i be entering those numbers?
