DEADBAND = 1e-04 This is why - you have deadband of 2.5 encoder counts. You will always settle on one side of it or the other. Set deadband to zero and you will be able to balance it. I don't think deadband is useful in velocity mode. You will always get dithering between adjacent counts - deadband just makes it dither across a bigger discontinuity.
