Make sure you are using the latest FOC firmware: https://github.com/jsphuebner/stm32-sine/releases

I believe the earlier versions of the firmware had a lower limit for the curki parameter.

Did you upload the Leaf parameters json config file? I had those errors before I used this parameters file.

Hi Johannes,

Yes, it worked with pinswap=4. I haven't tried changing any parameters yet. Waiting until we finish mounting the motor in the truck before we try adjusting parameters.

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...

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 ...

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 ...

I have installed the Leaf Gen 1 adapter with my V3 brain board into my Leaf Gen 1 Inverter, but I still haven't got the motor to spin yet.

The DESAT error is always asserted, even before I try to run the motor in manual mode from the web interface. Has anyone else made it past this point?
