ABSTRACT:
A system for orienting a rotating member includes a slow down and a stop sensor. A logic circuit receives inputs from the sensors to slow and stop the rotating member. A slow down signal must be received before a stop signal can effect the rotations. Starting is delayed to enable the motor starting circuit to go through the necessary start up sequences.
