ABSTRACT:
A multiple-rotation absolute encoder attached to an actuator provided with a motor and a reduction gear comprises a multiple-rotation value counter for counting a multiple-rotation value representing a number of rotations of a rotating shaft of the motor from a predetermined origin; a memory part for storing a reduction ratio R of the reduction gear; and a counter-controlling part for setting a range of the count value of the multiple-rotation value counter from zero rotations to (R−1) rotations on the basis of the reduction ratio R stored and maintained in the memory part, resetting the count value to zero when the rotating shaft makes a single rotation in a forward direction from a state in which the count value is (R−1), and setting the count value to (R−1) when the rotating shaft makes a single rotation in a reverse direction from a state in which the count value is zero. The rotation-angle position within a single rotation of the output shaft can be specified without the multiple-rotation value counter overflowing, even when the actuator rotates continuously in one direction.
