Grey line represents "-" so according to silkscreen everything is correct, but here is early pcb design that was working correctly, according to Damien: IMG_20190813_153216_030.jpg I believe same mistake is on this diodes as well: 20200820_234518.jpg Scheme differ from silkscreen: Снимок э...

I tried to power up Leaf VCU v2 board and didn't succeed. As I've seen on photos here, there is a shottky diode on the power supply lane, with grey line facing other way.
Is it placed correctly on my board?

Did you precharge main capacitor before connecting power supply?

Apologies for being thick, but if I understand correctly, Resolver pin #5 is now MSN and #2 is MSNG? If so, that is very odd indeed. Before swap sine, I've swapped cosine, it didn't helped. So I've switched it back. Red wire was connected to 5 and now it is connected to 2. 65576 Is it a typo? 65536...

Martin1775 - 60v is 1/5 of From factory was used with 288V

I've tested it with 100V with gas pedal both directions - it runs smooth and fast in forward, spun it up to 8000 rpm without load no problem. Still need to tweak of syncofs for smooth bakward spin though.

I just verified the MGR resolver polepair to 2. Set the motor to spin at ~1670rpm according to SW and then measured driveshaft flange speed with a optical tachometer to 244rpm. Result, 1670 / 244 = 6,84. Gear ratio is 6,86 so I call that a match! Yup, already came to this conclusion as well :) &quo...

So, suppose you had one of those signals backwards. Guess what happens? :) Back in a days when I've graduated from uni, I've got like 4 points out of 10 for mathematics... Geometry however was 10 out of 10 at the middle of semester.... 8-) what I'm saying is I never was good at those sinus/cosinus ...

Sorry for the previous post. I'm officially state that I'm now achieved confusion of the highest order: revolutions count changes whenever polepairs or respolepairs is changed. What changes in terms of signals when we reverse motor direction? Does direction depends on iq being positive or negative? ...

Interesting things I've found out about MGR (Sorry for the offtopic as this thread is not about MGR) Max_motor_current for the MGR is ~110A according to this: mgr stats.png Also according to this and my pure knowledge about motor polepairs, if there are 8 coils, there is actually 4 pole pairs. :? An...

What changes in terms of signals when we reverse motor direction? Hint : it helps to RESOLVE problems .... I love charades :) I think about resolver and motor pole pairs. One revolution of output shaft in mgr must cause 6.8 revolutions of motor rotor. I've started invertor, started revolutions plot...

Ok. Firmware 4.87R-FOC. Set pinswap 10. Started tuning and from the very begining syncofs = 0 it doesnt spin no matter the manualid. With manualid =0.1 manualiq=5 it spins CW, but it is reverse for MGR. So I've set syncofs = 32768. Now from gas pedal it spins forward no problem. I've spun it up to 8...

Sorry to hear that you get confused by the syncofs 22000, Konstantin. At the beginning from my tests I although have the 22000 for syncofs. Up to now I've only tested with the spezial software version Damian made for the pinswap. No confusion with syncofs. In the process of tuning I came from 0 to ...

Now that sounds like good idea. Thank you! Will try to check it tomorrow.

Ok, that sounds right. You might try to set pinswap for sin/cos Your inverter looks different from mine. At which phases are your current sensors? In mine they are 1 and 3, and if I chose any pwmswap except pf PWMoutput23, as soon as I enter any manualid, MGR starts to jump SO HARD, inverter shuts ...

bexander wrote: ↑Sun Aug 16, 2020 2:56 pm Maybe try the 4.87 firmware?
How have you connected the resolver and phase order?

I've checked with 4.87R already, nothing changed.
resolver connection MRFG-GND, MSNG-SIN A, MCNG-COS A, MRF-EXC A, MSN-ENC A, MCS-ENC B
Phases are connected straight 1,2,3 to 1,2,3.

I have checked/measured the resolver pole pairs for the MGR and to my understanding, 2 is the correct value. Also motor pole pair is 4. Did not helped unfortunately :( It was a moment at syncofs = 21950 manualid was 300A, and it did not moved but oil iside MGR started to evaporate :o ... still runs...

Ok, lets pretend ,I believed Martin1775 blindly and set polepais to 2 and respolepairs to 1, and connected U,V,W of inverter straight to U,V,W of MGR. I've used Damien's custom Prius GEN3 FOC software, and pwmswap was already set to "PWMoutput13" When I reached syncofs from 0 to 22000 even...

Connectors, that Damien sent me are black with no labels on them. Same about connectors, Johu supplies. I've bought plugs made by Connfly and they match perfectly.

I'm following procedure carefully, but:

I don't know what is max_motor_current, and what will happen if I exceed max_motor_current/2

Also, how incorrect value of polepairs and respolepairs will affect tuning process.
That is all, actually.

Does anyone know the part number or manufacturer of the 34-pin IDC connector plugs used in the Auris inverter board kit? I need a new strain relief thing and I want to be sure it will fit. Specially for those who banned in google :) 1658621-8 or T812134A101CEU plug 5102322-8 socket And if you go to...

So, it runs smooth but only in reverse.Only in MGR reverse. If only schaft starts spin forward, and accelerator is released, motor starts to jump uncontrolled. It happens only if I release accelerator. What could it be?

Before inverter overheated again, I've managed to spin MGR smoothly, but only in reverse direction. On the video it is clearly seen when motor hits rev limiter. But when I switch it in forward, when I touch accelerator, motor runs away, or atleast tries :D Motor tuned and connected precisely as Mart...

For safty reason you should be ready to switch off forward/reverse switch. Thank you for suggestions. Hopefully tomorrow I'll find small radiator to make liquid cooling and perform fine tuning. I'm working with pinswap1-3, when I changed it to "none" and set manualid to only 5Amps, it sta...
