摘要： The present invention uses a simple structure to precisely control a position of a rotator. A controller (1) sends a pulse for controlling rotation of a work (34) to a servo driver (2), and the work (34) is rotated by a motor (31) according to a reduction ratio as prescribed of a decelerator in which the motor (31) is driven by the servo driver (2) using a pulse quantity of the pulse for indicating an instruction position. The controller (1) includes a counting range determining part (132), and the counting range determining part (132) determines a counting range of an instruction position counter (21a) for counting the pulse quantity. The counting range determining part (132) multiples a prescribed pulse quantity of each turn of the motor (31) 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.
