VESC-Tool 2.04: FW 5 >> A BIG STEP FORWARD

Double like :heart:

Any tips here would be great. I get smooth operation out of BLDC with encoders but yet FOC refused to smoothly run with or without encoders. Prius MG1 motor

Do you need contributors to help with the translations ?

Done already. A native speaker Spanish would be good to go over the text.

Well done! Those look legit! :clap: :clap: :clap: :clap:

Might go on my first ride after all this lockdown thing and I’m not very keen on street face on the first ride directly, so I wanted to bring up this issue.

Do we have a fix for it or was the topic closed with „you need to set the duty cycle current limit manually on each vesc“?

I set it up in each VESC separately

So that’s it?
No fix to it?
And does it really solve the problem?
What if people do not know about it and just use the wizard :thinking: isn’t that a bit dangerous?

don’t shoot me…

i simply followed @Trampa’s tutorial…

The Wizard will get an update soon.

Do as I wrote and change the DUTY CYCLE CURRENT LIMIT START to 85% for each vesc.
It works great after that.
For the first time I can punch the throttle and keep it pinned down until I reach top speed even in steep inclines.
It also makes getting off the throttle at top speed smoother.

Honestly I had that problem since day one.
I am surprised nobody else had noticed.
I was just cautious and usually slightly let go of the throttle as I reached top speed.
Most of the times it wasn’t a problem but the few times I reached top speed under heavy load, things got sketchy.
I don’t know if some sort of smoothing was taking place in other vesc tool versions.

letting off the throttle from a good top speed run always gave me the heeie-jibbies… like everyone else here we thought that was a VESC feature… hahahaha and just lived with it… then last week I was lookin’ at the trampa tutorials to see if I could gleen some info… and the vid i posted above came up…

I tried it at 85… and I like it…

I still have to look into that HFI_erpm threshold setting that @b264 is on about and see if that is another uncovered gem!!

It’s called Sensorless ERPM HFI in the Motor Settings > FOC > HFI screen

Lower that to 750

You can thank me later

Synopsis time:

what’s it do? does it make the magic music last longer?

It just turns off HFI really quick once the rotor gets turning. In fact you can lower it even more than that, try 500. It only needs HFI when it’s not moving at all.

Once it turns off, you can dump as much power as you want into the windings. So basically it increases the window during which there is no cogging risk for extra high motor current levels.
