Control system

The control system has a data acquisition unit (1311) and an analysis unit. A data acquisition unit (1311) acquires holding object information indicating information of a holding object held by a holding device of an industrial machine, a holding state of the holding object to the holding device, and machine information indicating information of the industrial machine. The analysis unit determines a cutoff frequency, which is set in filtering processing of a motor control device that controls a control object provided in an industrial machine, to a cutoff frequency set in filtering processing of the motor control device. The natural vibration frequency of the mechanical structure generated in the mechanical structure including the control object and the holding device when the holding object is held by the holding device is derived. The analysis unit derives, on the basis of the holding object information, the holding state, and the machine information acquired by the data acquisition unit (1311), the natural
