Abstract
The present invention uses a simple structure to precisely control a position of a rotator. A controller () sends a pulse for controlling rotation of a work () to a servo driver (), and the work () is rotated by a motor () according to a reduction ratio as prescribed of a decelerator in which the motor () is driven by the servo driver () using a pulse quantity of the pulse for indicating an instruction position. The controller () includes a counting range determining part (), and the counting range determining part () determines a counting range of an instruction position counter () for counting the pulse quantity. The counting range determining part () multiples a prescribed pulse quantity of each turn of the motor () by a reciprocal of the reduction ratio and a correction value, and determines the correction value which enables a multiplication result to be an integer.
