Inverter Firmware v5.14.R

This is merely a bug fix release, so not too many, but significant changes:
- Using filtered frequency to calculate syncadv
- Fixed bug with regen ramp
- Also downramping throttle with throtramp
- no longer limit d-controller output to half amplitude. Can cause unwanted regen
- Removed unused hardware variants

Installed this version instead of 4.96FOC on the Leaf engine - the regeneration disappeared. This is fine? How to get regeneration back?

can you try setting pot2min=pot2max=0
Must be some combination of settings that I don't test as regen works on my car.

I can not do this. The wires from the accelerator pedal are directly connected to the inverter board without CAN

On the weekend I tried to put different versions. All versions from 5.05 (5.05, 5.11, 5.14) do not have recuperation. When installing version 4.96 or 4.97, recuperation appears immediately. Something in the code is not correct.

Can you post the parameter json file

You have configured the second pot input to adjust regen. Are you using it as such? Otherwise set pot2min and pot2max to 0. I believe I have changed the behaviour somewhat since 4.97

OK. I am not using the second potentiometer yet. I'll try to change it. Thank you.

Everything worked out. Although the connection with the pedal is not clear. Thanks Johu.

See here:
https://openinverter.org/wiki/Parameters
potmode
0=Pot 1 is throttle and pot 2 is regen strength preset
1=Pot 2 is proportional to pot 1 (redundancy)
2=Throttle/regen controlled via CAN (like 0)
3=Throttle via CAN with redundancy (like 1)

Get wrong Idc in 5.14, but all good in 4.96
At no spin is like -18, rises slowly to 0 when spinning. Older FW Idc was measured OK.

In the code 104 and 105 lines use idc twice. Like second line overwrites firat idc calculation.

I will have to test this but currently I'm out of office. Will check later this week.
The various lines are just pre-calculations, the final value is set in the Param::SetFixed() call
EDIT
what I can say for now is that since 4.96 the calculation was changed in two ways:
1. the d-current and voltage is also taken into account, before it was just q-current
2. The result is filtered to smooth out the DC current limiter

Sometimes IDC shows ok. Sometimes too low.

Just a note to clarify an issue/solution discussed above: With this version, if you are only using one potentiometer/pedal, set pot2 min and max to the same number, or you won't have regen.

I use only POT1. POT2 min/max are set to 0 and I get regen.

I’m having an ongoing issue with sine UDC randomly measuring too low when switching from waitstart to run. Any advice gratefully received.

Hi!
I discovered a serious problem due to the fact that my buggy is all open and the high-voltage battery along with the contactor is on the street next to my ears. there is no sequence or reason, however, sometimes when the ignition is switched on, the main contactor is triggered for a short time!!! only after that, the pre-charge relay turns on and then, after pressing the start button, the contactor again. This is very bad, the contactor clearly does not like to turn on high voltage for half a second without precharging. What to do about it? this does not always happen, sometimes everything is as it should be.

I don't remember every setup... which board? Specifically with this version or any version?

I'm assuming it's a V3 + adapter board Nissan Leaf. It was similar for me - when turned on, an impulse passes to the main contactor. Because of this, the main contactor is welded. I set a timer to turn on the main contactor.

all right. foc version 5.14.R and board version 3.
how to set the timer on the main contactor?

I got the same problem with high impedance load.
I don't think this can be version related.
