Hey there!
When Im using FOC-Mode with my Turnigy Propdrive 6374 it accelerates very well and drives smooth and fine but on rapid braking I get a cut-off.
It only happens on rough braking at middle speeds. After reading my fault-codes I got this: (and am a little worried about the -279A oO This cant be true I guess!?)
Ive read about adding another capacitor to C18... Anyone knows if that helps? Doubling the Observer gain just made it worse.. Im not sure if reducing it to half (10%) is a good Idea?
Thanks for any help!
:)
Hi
the current is the phase current afaik and therefore far from the RMS current which is mostly interesting.Do you use Regen Braking? As the internal (=measured) current is normally only increased with caps (but helps with stabilizing the battery+VESC itself). I'd check if not the measures Ri of your settings are problematic. In a few of my threads I mentioned my startup problem and the adjusting problems as Ri was far from the real value in my first setups. With a lot of tests I defined a middle value and since then my overcurrent problems were solved.

Thanks for your answer!
I do use regenerative braking...
Hobbyking says that the internal resistance of the Motor is about 0,016 Ohm VESC-Tool reads about 11,4mOhm. How dangerous is it to adjust the value?
After replacing the battery with a fresh one I experienced the start-problem even in BLDC.. By giving too much current, the motor just stalls and freewheels... but why? I don't trust this board anymore :(
Trying to get bluetooth to work but even with a HC-05 or HC-06 that isnt working either.... Is there something I am missing?
