I tried h, qh, qhi modes. qh and qhi seemed symmetrical - I watched encoder velocity. Motor rotated approximately at 1100 RPM, when bldc value was set at max, 0.95 or 0.95 respectively. I think it should had made something close to 3000 RPM at that point, right? The thing is that when I was playing with frequency and value pins in n mode, I got it to 3000 RPM with frequency = 200 (because there are 4 electrical revolutions in one motor shaft revolution) and value = 0.8, so it is capable of that. The question is - what is missing? I would appreciate any ideas, how should I proceed.
