Thank you Azzuro,

I also have the 12 pages of electronic diagrams that help me understand part of the operation. I am still sending you my email address which could be used for the future...

Have a good day,

Lionel

Sylvain, 
Do you have a link for the VECTRIX WORDWIDE Whatsapp Group ?
Thanks

Hello Azzuro,

Via the J5 connector, I was able to control the signals coming from the encoder. I found square signals on the 2 inputs "Encoder Incremental Input". Those are signals whose frequency varies with the rotation speed. About 5Khz at 10km/h. As I don’t have differential oscilloscope probes, I couldn’t visualize signal A compared to signal B. So I don’t yet see how the processor measures the angle in degrees (but I will try soon with isolated probes).

No signals on the "Encoder Hall Sensor Input" inputs.

To control the signals at the input of the IGBT, would you please have the layout diagram of the components? I can send you my email if you want.

In advance thank you!

And especially thank you for your help and patience :) !

Thank you very much Azzuro,

I will try to take measurements this weekend.

- return signals from the encoder

- input and output of the IGBT (paying attention to the different GNDs)

Have a good weekend,

Lionel

Bonjour Azzuro, voici les dernières nouvelles : (en anglais plus bas)

J'ai remplacé le fusible en panne. Après remontage du contrôleur moteur, je n'ai plus les erreurs "CAPCur" "Vcellow" "Vcellmax" sur le tableau de bord.

J'ai fait votre diagtest et je n'ai rien relevé d'anormal, pas de "0" , pas de "nots".

Par contre je n'arrive toujours pas à étalonner l'offset du moteur et j'ai toujours des accélérations chaotiques.

J'ai utilisé un oscilloscope pour visualiser les tensions et courant moteur. (avec un filtre <3000Hz) Je vois bien les 3 tensions de phases. Je constate cependant qu'en fonction de la position de la roue (chaque cran doit correspondre à 1 aimant et 120° du capteur) il y a une position sur 3 ou je n'ai pas de tension et rien à l'accélération.

Je n'imagine pas que le moteur puisse être à l'origine de ce problème.

Est-ce que l'outil de diagnostique permet de visualiser la position du capteur en live ?

Je peux vous proposer un échange téléphonique ou par visio pour vous montrer la forme des signaux que j'ai enregistré si cela ne vous dérange pas trop.

Bonne journée et à bientôt,

Lionel

Hello Azzuro, here is the latest news: (in English below)

I replaced the broken fuse. After reassembling the engine controller, I no longer have the errors "CAPCur" "Vcellow" "Vcellmax" on the dashboard.
I did your diagtest and I didn’t notice anything abnormal, no "0", no "nots".
On the other hand, I still can’t calibrate the offset of the engine and I always have chaotic accelerations.
I used an oscilloscope to view the motor voltages or current. (with a <3000Hz filter) I can see the 3 phase voltages well. I notice however that depending on the position of the wheel (each notch must correspond to 1 magnet and 360° of the sensor) there is one position out of 3 where I have no tension and nothing at acceleration.
I can’t imagine that the engine could be the cause of this problem.
Does the diagnostic tool allow to visualize the sensor position live?
I can offer you a telephone or video exchange to show you the form of the signals that I have recorded if that doesn’t bother you too much.

Good day and see you soon,
Lionel

Thank you Sylvain for this new possibility of contacts!

Thank you very much Azzuro,

I could test this diag mode as soon as I have received the fuses to be replaced on the MC board and reinstalled everything. I will keep you informed as soon as possible...

Beautiful day, (here it’s rain and snow since this morning in Savoie)

Lionel

Well, I have only 4 Hex files download from the site https://vectrixparts.userecho.com/

MCR2042-4.hex

EVPS LiMn 36s-2.hex

DIY_1708.hex

BMS R64 9cell.hex

I’m sorry, next time I would import smaller photos

Hello Azzuro,

Thank you for your analysis. I am sending you pictures of the BMS cards, the installed pack, the labels on the MC, as well as a screenshot of the diagnostic tool that must read the software versions (if this is indeed the case).

I extracted the MC board and found a fuse out of order. (on the picture) I started doing reference searches equivalent to T 40A 250V and it’s not easy to find a reference that can match.
