Abstract:
Provided is a noise compensation adjustment method. One embodiment of the method comprises: a measuring step of measuring noise by driving a motor with respect to a coupling system including the motor and a driving body coupled to the motor and driven by the motor; an order specifying step of specifying an order B of components contributing to the compensation of the noise among the k-th component and the 1/k-th component (k is an integer) in the rotation of the motor on the basis of the noise measured in the measuring step; an adjustment step of controlling the drive of the motor with the component of the order B, which has been specified in the order specifying step, as a compensation value and adjusting the component value of the order B to reduce the noise; and a recording step of recording the component value of the order B, which has been adjusted in the adjustment step, as a compensation value for reducing the noise.
