Abstract

PURPOSE:To always set an origin restoring position on a fixed position by rotating a pulse generator up to a previously determined optional position other than the origin position and then rotating the pulse generator until an origin pulse is inputted from a prescribed direction. CONSTITUTION:The system has the pulse generator for outputting an origin pulse every detection of an origin position and a potentiometer 10 connected to the pulse generator 9 to detect the rotational frequency of the generator 9. Even if an origin restoration command is inputted from any position of the pulse generator 9, the pulse generator 9 is temporarily rotated up to the previously determined optional position other than the origin position. Then, the pulse generator 9 is rotated until an origin pulse is inputted from the prescribed direction, the origin pulse can be detected from always the same direction. Consequently, the pulse generator 9 can be restored to always the same origin restoring position.
