Abstract
A device in which a processor controls a desired frequency and a desired instantaneous angle of a pattern generation circuit. The processor also controls a desired amplitude of the system. The pattern generation circuit includes a ROM having firing data for only a portion of the angles for which the circuit produces output. Output for the angles stored in the PROM and for the remaining angles is generated using the partial data from the PROM. The processor selects the desired voltage levels of the motor output, and can instantaneously set an angle of the output.
