A rotation control unit performs a rotation process of rotating a servomotor which is connected to a device via a power transmission means. A waveform-data acquisition unit performs a waveform-data acquisition process of acquiring waveform data when the servomotor is rotated. A determination unit performs a determination process of determining whether or not rotation has been transmitted to the device when the servomotor is rotated, based on the waveform data. A calculation unit ends a repetition process of repeating a search process, the search process being constituted by the rotation process, the waveform-data acquisition process, and the determination process, when it is determined that the rotation has been transmitted to the device, and calculates as a backlash amount, a sum of a rotation amount in the repetition process, the rotation amount being an amount by which the rotation control unit has rotated the servomotor in the rotation process.
