Re: Leaf Gen 1 board

Thanks. Updated the firmware and the parameters uploaded successfully but the errors are still there unfortunately and no luck with the motor. Think I may have to do more digging. Make sure you are using the latest FOC firmware: https://github.com/jsphuebner/stm32-sine/releases I believe the earlier...

Re: Leaf Gen 1 board

Seems like I may be having issues with the parameters then. I did upload the parameters.json file but got "out of range" error message when it tried to set curki to 20000 and for another parameter. I think That may be the culprit. I'll try tinkering with it a bit more when I get home and h...

Re: Leaf Gen 1 board

Thanks. After removing DESAT pin, did you just have to put power to pin 7 and connect grounds to get the inverter working? I tried and had no luck. Here are the basic steps I followed to get the motor spinning: Connect the brain board to get Gen 1 adapter board with DESAT pin removed Connect the st...

Re: Leaf Gen 1 board

That is very useful feedback. Too bad the universal brain board approach doesn't work here. How much extra room would there need to be? Would it work upside down? The DESAT pin feeds into a NAND tree, i.e. it must be high in order for PWM to run. Inversion needed... Maybe an NPN transistor for now ...

Re: Leaf Gen 1 board

Update: Got the motor spinning! We had to remove the DESAT pin (and connect the forward pin to 12V...). Looks like the alert signal on this Leaf inverter is active high instead of active low. Does anyone know if this polarity is easily changed in the brainboard firmware? If not, it might be easier ...

Re: Leaf Gen 1 board

I wish I found this thread earlier, I was unable to find the white connector anywhere after damaging the first one and had to buy a replacement inverter just for the connector. Good news is the inverter is only $200, Now I have 2 inverters for whatever reason and know where to get a hold of the conn...
