A method and apparatus are provided for controlling the operational characteristics of a motor. The method includes the steps of reading a plurality of optically encoded controller position signals, determining a motor control signal state and differential based thereon and outputting a motor control signal. The central operation of the method and apparatus is based on a motor control signal state diagram and the transitions therein. The apparatus includes a rotary digital optical encoder having a plurality of output signals, a programmable controller device and an output circuit. The programmable controller device includes motor control logic for determining the operational characteristics of a motor. The motor control signal may be either/or a pulse width modulated (PWM) or analog output. Additionally, described embodiments include an apparatus having logic for determining the directional characteristics of a motor.
