ABSTRACT:
A circuit for varying the rate of velocity changes of a digital motor wherein the motor produces movement that is commanded by successive lengths with each length having an extent defined by a whole number of steps and in which each length by its extent sets its own velocity whereby non-linear velocity changes in accordance with motor speed are obtained from a command that includes just length extent information.
