Update from 4.12 to 4.76R, give HICUROFS1
Posted: Wed Mar 04, 2020 1:04 pm

I upgraded the firmware from 4.12 to 4.76. (Bootloader v.3)
And now I get [11]: WARN - HICUROFS1
And [4952]: DERATE - CURRENTLIMIT after I turn ignition.
Are still in RUN mode, but very weak start, probably because of derate.
Not sure if I'm in derate? Since 'din_desat Ok' and 'din_bms Off'
Have the same parameters as before: (except for new ones, are default)
Any suggestions?

DERATE - CURRENTLIMIT refers to iacmax. Which is weird because you set it to 5000A and the gain factors would only allow ~800A

I barely recall there was some bootloader issue with 'ACTLOW' setting.
Not sure if I use the correct bootloader, where can I d/l the correct one?
What does the numbers mean [12960] and [4952]: DERATE - CURRENTLIMIT

[4952] is the time since boot in 10ms when the message occured. So 4952 would be 49.5 seconds after start.

HICUROFS1 fault is fixed (was updating wrong board
)
Still get DERATE - CURRENTLIMIT on last err.
But din_ocur is Ok, din_desat is Ok, din_bms is Off and still in RUN mode.
I get DERATE - CURRENTLIMIT when ignition is switched, does it go back to "NO DERATE" after supposed current peak?
If so could I just ignore it, or should I do some real test with current clamp and scope?
But why does it only trigger DERATE and not OVERCURRENT?

DERATE just means it measured a current higher than iacmax and therefor dialed back slip and sine amplitude. This is temporary, as long as max(il1, il2, il3) > 0.8*iacmax. il3 is calculated from il1 and il2.
OVERCURRENT would mean the comparator tripped and PWM was shut down by hardware.
The strange thing is that you have iacmax set to 5000A and your current sensors can only measure 900A. Can you try setting iacmax to 1000A? Maybe there is some integer overflow involved.
Otherwise comment out the limiting code and recompile.

Will try to set to 1000A.
I think my current sensor is correct: this is the measurement I get with 10 winding around current sensor.
Amp: Out: In to uC:
500A 4,96V 3,37V
400A 4,46V 3,03V
300A 3,96V 2,69V
200A 3,46V 2,35V
100A 2,97V 2,02V
0A 2,48V 1,68V
-100A 1,98V 1,34V
-200A 1,49V 1,01V
-300A 0,99V 0,67V
-400A 0,50V 0,34V
-500A *0,47V *0,32V
The iacmax is new setting in v4.76R, is that why I don't get the fault in 4.12?
Am I correct in assuming there there is no to high current spike, since the HW overcurrent is not tripped?

Tried that no change.
Have hooked up a current meter with max/min, and there is no current spike at ignition switch on.
Also did a plot:
BTW: is the ilmax max current for hole trip, until reset?

ilmax is calculated on each PWM interrupt, MAX(ABS(il1), ABS(il2), ABS(il3))
Strange... is power still reduced?

ilmax, I was wrong again, not always easy to know what the different (undocumented) names mean.
It would be very useful to have a spot value, that save the highest measured current since start.

I'm sure it would be nice to have it documented, now that you know

Have added the missing Spot values to wiki:
hwver, lasterr, ilmax, cruisespeed, turns, angle, pwmio and canio
Is uac obsolete, or just missing in the web interface?
Have also added:
fslipconstmax
throtmin
Have not described all of them.... I could guess, but would rather get some hint.
Please correct me if I'm wrong.

Yes thanks very much. I added the description where it was missing.
uac is not implemented in FOC version but it is calculated AC voltage in sine version
