ABSTRACT:
A drive control system for a step motor. The system includes a detector for detecting when the step motor is central between step positions of the step motor and for producing a timing signal representative of the central position of the step motor. Motor drive coils selectively driven by a drive control circuit actuate the step motor. The drive control circuit receives the timing signal and in response thereto selectively actuates the motor drive coils to allow the step motor to stop at its next step position.
