My engine rotate in wrong direction and the vehicle drive backwards.
Can I swap wires only in direction switch ?

Thanks
The phase order is weird, is pinswap still 0 ?
pinswap = none = 0
By "supply current" you mean DC current ?
yes
Basically the inverter is a buck converter, so output current is always higher than input current.
ok now I understand
Try to test if you can spin in both directions and it ...

What are your current parameters?

The parameters are on the first page

When I swapped the motor wires physically, engine started working
I connected as follows:
Engine U - L3 - PWM3
Engine V - L2 - PWM2
Engine W - L1- PWM1
Why ?

Below is a photo of the readings

If you have current sensor errors with FOC code you need to switch them on the board or inside software. I did the same mistake when designing according to old rev2 board made for ACIM motor. There sensors were there only for monitoring overcurrent protection. But with FOC code you really need to ...

Hm... why exactly did you take driver board off Leaf IGBTs then?

I have several first generation inverters after bathe in the ocean, so I was hoping to use modules IGBT.
I think that, I should buy Nissan inverter first or second generation.
I have Nissan engine first generation, so maybe I ...

What does your fault pin says?


I have only hicurof error

I connected IGBT to Gate Driver in several ways but it probably doesn't look good.
I think that my IGBT is broken or the Gate Driver is wrong adapted to Nissan IGBT.
What Do you think about measurements below ?
Could anyone borrow Nissan IGBT, or maybe anyone had similar problem ?

I connected IGBTs to Gate Drivers
20200119_205903.jpg

After a short worked, each SI8261BBC for TOP side failed and Gate Drivers began to draw large current 0,3A -0,6A each one separately.
After replaced SI8261BBC draw current is ok and signal is probably correct.
But I ask myself why there was a ...

I didn't find the answer to problem number 2 on the forum. Why I have hicurof errors ?
Regarding point 3, I found a fault in every Gate Driver.
After replacing SI8261BBC for each TOP, the signal is probably correct.
I will continue the topic of the Gate Driver fault at: https://openinverter.org ...

I did not change something while connecting resolver or phase wires, only Gate Drivers began to take more current.
I have several first generation inverters after bathe in the ocean, so only: IGBT, current sensors, capacitors, power rails, housing are good.
The producer assured me that it would work ...

I connected to IGBT 58V, but engine doesn't rotate
In the past, the engine rotated at one speed as see in the film at the top.
So If PWM is ok, maybe IGBT or Gate Driver is damaged
Below picture and link, how I connected IGBT to Gate Driver

I can't make resolver calibration because engine does not rotate.

Below is a video of the results after several months work

Why the engine has only one speed ?
Why gate driver consume 0.4A ? Is the value correct ?
Resolver consume 0,04A , Is the value correct ?
Should I increase the voltage from 28 V to 52V for IGBT inputs ?
Parameters ...

With respect Daniel mate I don’t think I have. My drawing’s crap I admit, but the testing worked and I’ve just double checked the wiring colours match the information in the Leaf’s EVC manual (I used green for SIG in stead of white). Are you sure you have the numbering oriented correctly ...

I connected pin 11 JP2 to 12V and calibration succeeded
In the next step I calibrated voltage sensor and connected gate driver and IGBT
I connected small engine on 30V to IGBT
When I entered "start 2", the engine does not rotate, I connected (pin 11 and 13 JP2) to 12V
Should I do anything else ...

Do you know how to connect a acceleration pedal from Leaf I ?
Which pin is: +5V, -5V, sig 1, sig 2


Hi Daniel, did this part of the question ever get answered? I would like to use the original Leaf 1 throttle pedal with Damien’s VCU and it needs these 4 outputs to operate.

Why the displayed current value in the program does not change ?
I give it 5A * (1.5mm² cable 10 times through both sensors) = 50A
