PROBLEM TO BE SOLVED: To provide a positioning system, which is capable of correcting positioning errors that are caused by angle transmission error of a reduction gear, while maintaining the consistency between a position instruction and the motion of a motor rotation axis. SOLUTION: The positioning system 1 has an actuator 7, a motor driver 8 and a controller 9. The controller 9 corrects the generated position instruction 11, on the basis of error correction data 12 for correcting the positioning errors caused by the angle transmission errors of a wave gear reducer 4 in the actuator 7 to output a position instruction 11A after correction to the motor driver 8. The motor driver 8 drives a motor 2 on the basis of the position instruction 11A. The positioning errors caused by the angle transmission errors of the wave gear reducer can be corrected to perform the positioning with accuracy, while maintaining the consistency between the position instruction 11A and movement of the motor rotation axis 3.
