PROBLEM TO BE SOLVED: To provide a frequency conversion control system for a shredder with which energy is saved. SOLUTION: The frequency conversion control system 20 includes a thickness sensor 21, a variable speed motor 22, and a control module 23. The control module is connected to the thickness sensor and the variable speed motor, and includes a comparison table 2321 (not shown). The thickness sensor detects the thickness of a shredded object inserted into the shredder 2, and the variable speed motor is configured to be operated at different motor rotation speeds. When the control module receives a message T about the thickness of the shredded object, from the thickness sensor, the control module searches motor operation data corresponding to the thickness from the comparison table, based on the thickness, further outputs the motor operation data to the variable speed motor, and controls operation of the variable speed motor to an appropriate rotation speed, thus waste of energy is prevented.
