I'm very interested in using your AX500 in a remote camera pan and tilt head application. I have only one requirement. Will this controller (using dc tacho feedback and controlled by a resistive joystick) run a motor very, very slowly at one end and also full speed at the other. Your data sheet seems to suggest it will. The reason I ask this question is that I've tried a few cheap board from Dimension Engineering and Pololu and there is a dead area where the motor has no speed, then suddenly jumps into life at about 200rpm. I need far more subtle control at the low end and less at the top end.
