That "excessive" Pgain is why it is as close as it is. But I will try it. Pgain also stiffens it under load. > > I would suggest zeroing all gains, adjusting FF0 until one middle speed > is spot-on then adjusting Igain to pull the other speeds up or down to > target. Middle speed in the ratio's, or middle speed in the absolute, which would be around 600 rpms. But in 2/1 ratios 30 60 120 240 480 960 would put 180 rpms at about the center of the range.
