After days of testing, swapping and swearing we have results! The car drives very smooth, and seems pretty efficient too. I'm still driving with a 100A fuse (72S Li-ion), but this will probably die fast, once we gonna try some fast 0-60Km/h :-) The trick; I lowered the curkifrqgain from 50 > 0 and C...

You turned it off completely, already by setting brkmax=-1. idcmin essentially just limit brkmax. So it is some controller overshoot that still causes unwanted regen. I'm assuming it is just a surge and than tapers off? Parameters you can play with, one at time: - curki - increase/decrease by 2000 ...

Yes... this is why i went Lebowski route for my immediate conversion. Where is your max RPM point? Can you extend that to 600Hz? You may also change "idcmin" to 0 to try to get rid of regen. I tried the idcmin to 0, and unfortunate that didnt work. When I plot 'idc' while turning, it stil...

Uh lets not send people to another system but rather solve the problem here. What version are you running? I remember that issue from way back. Only parameter that is different from mine is curkp=64, I have it at 32. I'm still very pleased with the FOC performance. test run was great, until ... I t...

Hi guys, After a first run on the road, I have an issue (VW Polo with a Prius Gen 2 inverter and outlander rear motor) when accelerating until approx 200Hz you can play with the speed, and remove you foot from the throttle instantly without problems. But once on a higher speed and remove foot from ...

Thanks MJC506, this helps.
then a 300Hz in my case(5 polepairs) is nothing special

Agree, for some of this forum its obvious others dont have a clue about this kind of details (like myself), the wiki helped me a lot and took me at this piont, so this simple instructions are great help. Another question: what is a reasonable/recommended "fmax"? its now set to a 200 but I ...

Yes, try something between 2 and 5. throtcur is motor current while idcmax/min refers to battery current. At low speed/startup motor current can be many 100 amps while battery current is just a few amps. Thanks, It runs great! Changed "throtcur" into 2 (also tried 3, a bit to aggressive),...

Thanks, will give a try with a higher "throtcur" like a 2 or even 5?
Do i need to increase the "idcmax" accordingly ? from a 150 to an 300A?
About the throttle, i still use a pot

forgot to mention, I'm running 4.87.R-foc

Hi Guys, Its been a while, but I need your help. I've mounted my outlander motor to the gearbox and fitted it into my car (VW Polo mk1) last days I'm testing the motor and inverter, watched hours on video's and found my (i believe) the correct "syncofs". but now mounted, with wheels off th...

a little update on my 180Amp aventure; (gen2 inverter - outlander rear motor) Played with the syncofs and went from 180 to 1 amp from Battery with manualid 1 changed syncofs from 0 to 9000. Dont know the rational behind it (yet) I do have a plot (need to figure out how to upload) that shows with syn...

After Johu's post it was very clear. If you want to feel me like an idiot? you succeeded! Therefor I apologize for not being perfect, and still learning while making mistakes. Respect your years of knowledge, hopeful you respect my learning curve with "stupid" questions and actions. There ...

Congrats Zookeeper! I've got it also running smooth with FOC, with a bit of different parameters, like I donthave the Pinswap (0), and my deadtime is 183. While running, the inverter needs a lot of current from 24V battery. like 180Amps! that keeps me away from playing with parameters with such a hi...

I'll take a look tomorrow when I am there and get back to you on that. I can't remember off the top of my head. I found that on throttle my motor is a bit more unsteady, it will also sometimes not move and draw a bit of current. But I am not sure how much of that is to do with the PWM wires on the ...

Does anybody knows why we have jumpers Sj1 and Sj2? SJ1 and SJ2 are for ENCODER use only! They activate pull-up to 5V. Do not close them for resolver. Set encmode to resolver. Thanks guys, I did set encmode to resolver as one of the first things. and also with a plot resolution of 10 and 1000. With...

Does anybody knows why we have jumpers Sj1 and Sj2? I'm struggling with getting a nice triangle out of my (outlander) resolver, and watched video's again from Damien, where he showed his prius transaxle with a nice triangle signal from his resolver. also tried it, with Sine and hand, but without suc...

I have the motor running on the Prius gen 2 inverter. This is just in manual mode for now. Still need to tune it all in and get the throttle plugged in. But it seems quite smooth once it's moving. Again great work, perhaps you can help me. I Also hookup up my Outlander rear motor and Gen2 inverter ...

Hi Johu,

it works!!
Thanks, I've got it running (on sine) smooth without any errors. with 3 similar amp, nothing abnormal or weird. Thank you for checking Johu

You should certainly see an INPUT to the array when fstat > 0 and amp > 0 e.g. by setting fslipspnt=1 and ampnom=1. Could it be that pwmpol is set to ActiveLow? If you can't see pwmpol type "flag pwmpol ~hidden" into the custom command field and refresh. The Darlington output of course on...

Thank you, correct.
I first try to get my induction motor on the sine software running, once successful I will hook up my outlander motor. want to avoid to destroy my outlander motor.

In general it is hard to control motor speed of an unloaded motor with the throttle. Throttle input controls torque and of course very little torque will spin an unloaded motor up very fast. You can try using the idlespeed parameter for testing as well. Thank you. Makes sense. Something else; I've ...

Great work LRBen! I have the same plans and equipment (with a 48V test powersupply). you are ahead, paving the way. Thank you. unfortunate I'm stuck for a few days with the DESAT error. would you mind sharing Parameters, or your IL1 & IL2gain? Perhaps this solved my DESAT issue. Thank you, keep...

Great work LRBen!
Have the same combination, willing to share Parameters? I'm stuck for days on my DESAT error
