here is the issue @Deodand had mentioned.
Thanks for the info @rafaelinmissouri very interesting informatiom you have provided!
Btw i am no guru whatsoever so i have no idea what values to check etc.
Sorry but that is beyond me.
and regarding the values. what i used as a reference was the recommended motor amps. and expected them to be within 5 amps or so.
so mine were way different regardless of which motors i tried.
This jumper wire just connects V+ to V+… it really shouldn’t do anything and can likely be removed. No idea why that would be there, there is a big V+ power plane of copper connecting these.
How weird, do you think the 3 repaired half bridged need to be redone?
Thanks for your help to mister!
Half bride is one leg of the Mosfets that controls a phase. Not sure what you’re refering to. I asked you the check the mosfets just to see if they’re whole, resistance should be in the ballpark similiar to the other side of the unity f.e
Ok will check, sorry, like i said im pretty bad with this stuff.
No problem, if we’re speaking greek just point out what is unclear to you
Would you mind pointing me to the fets and what points to measure? All the components are unmarked as in there are no serial numbers etc on them.
I think it wasnt always this bad actually, i just uploaded this video and noticrd that it worked better, not good at all still but i think it was better?
Im having this exact same issue with two Trampa VESC6 MK3’s that are known-good. I just updated them from fw4.2, where they were working perfectly, to fw5.2, where I am now getting issues detecting the proper motor values and sensors.
I have also now heard from a previous customer that his Xenith is having the same issue.
I think it’s a problem with FW5. I will be doing more testing on my setup to try to figure it out.
This could very well be true,because that film was them running on unity firmware i think
I can confirm that the customer of mine had his issues resolved entirely by switching to using the Unity app and firmware.
@Trampa, I think we found a bug.
you can check source drain and gate with continous mode and meassure resistance through the 3 Phase Wire Points, Compare it with the working side.
iam not in the shop but I think it was this mosfet layout
Update: i tried it with unity firmware and its still not good, so in my case its most definetly not software. Ill check for the mosfets now.
Sorry for the late update, i was away for a few days.
Am I the only one looking at those phase leads thinking they need to be completly redone?
Which ones, you mean on the board right?, the reason why they look like that is because i soldered them off by accident and squished them, they are hairy but definetly not cold i can tell you that. I think they look worse than they are
