Re: Nissan Leaf Gen3 Drop-in board

With above settings rotating shaft clockwise (facing the shaft) angle plot goes from low to high. Should it go from high to low, i.e. removing the SINCOS pinswap?

Re: Nissan Leaf Gen3 Drop-in board

Maybe add resolver to pinswap? Has anyone compiled parameters that will work with the stock motor? I tried to compile from this thread https://openinverter.org/forum/viewtopic.php?t=980&hilit=udc&start=75. The settings I have tried below: Especially unsure about the "il1gain": 1.8...

Re: Nissan Leaf Gen3 Drop-in board

Had a shot at getting things moving over the weekend, but only rattling/sounds so far and going into DESAT error if too much torque(POT) applied. Resolver input is giving nice plot. Guess there are settings/jumpers that needs to be figured out though... Happy to test things out, only using 48V so pr...

Re: Nissan Leaf Gen3 Drop-in board

Thanks, both. JRBE, you were on the right track, but still not low enough. 0K5 brought it down to room temperature with the Gen2 profile, but unsure if it fits the old profile from there. Now to some testing with load... Hah, goes opposite direction vs temp so definitely needs new profile in fw and...

Re: Nissan Leaf Gen3 Drop-in board

Finally got to this again. One of the 5V pins had lifted off the pad thus disabling UDC and TMPHS measurement. All works as before now. Good one :) With the STM32 in reset it sits at 0.544V instead of the calculated 0.4V. So then I cut the brake jumper and now in reset it sits at 0.75V. With the ma...

Re: Nissan Leaf Gen3 Drop-in board

I'm slowly picking away at the updates to the board as issues are found. glink, when you get some free time can you please double check the 113.5mm dimensions? I drew the board up to 113mm across the top and bottom hole spacing but it looks like it might be 115mm. The .5mm difference won't be enoug...

Hi, tried to wrap my head around the regen setup when testing out on the bench with a "dyno" setup with two em57's against eachother. I want to control the regen with CAN, but I see very different behaviour when regen is controlled by CAN vs when I "set" potnom using offthrotrege...

Hi, the settings here has helped a lot. I have set up a "dyno" rig to try to find out how to configure my setup for my boat using only 48V. I'm using Auris inverter (about the same spec as Prius inverter I guess) and Nissan EM57 motor. The KV of the EM57 is 18.46 according to sources, and ...

Re: Does Anyone Have a Prius Gen 3 Inverter, A DC Power Supply, and Some Way of Measuring Output Voltages of The Inverte

I have some recent experience with this and I'm using the boost circutry to boost to 120vdc because I thought I needed it to achieve higer rpm on the Leaf motor, but I'm only able to get 3kw output resulting in about 1000rpm in my setup...asked about this on another thread btw.

Have tried boosting in the range of 120V to 300V but that does not change real output much. Everything runs smooth and nicely, but expe...

Re: Testing FOC for synchronous motor

First I assume you've calibrated your potmin and potmax. Second, spinning without throttle usually indicates an incorrect syncofs setting. Have you calibrated that yet? Thanks to both! Haven't calibrated anything, I do the POT adjustment with CAN communication. Potmin=0 Potmax=4095 Throtcur=1 No, I...

Re: Gen 3 inverter converter control software

Hmm... Reset should happen if the board is built 'properly'. Is there a manual reset you can try? For now, the culprit imho is the FTDI board. Uploaded a sketch with the Atmel ICE, but still no serial I/O. Until I get a new FTDI board I will program using the Atmel ICE, but it's a bit more cumberso...

Re: Gen 3 inverter converter control software

I think you have the programming cable in the opposite direction, the gnd (black) should be facing the center of the board and not the edge. The silk screen (white text on the board) should read "blk" where the gnd goes. If none of this works, try swapping rx and tx on the programming cab...
