PROBLEM TO BE SOLVED: To provide a control device for a non-excitation actuated electromagnetic brake, which can prevent the non-excitation actuated electromagnetic brake from quickly not acting. Kind Code: A1 A control device for controlling the operation of a non-excitation actuation type electromagnetic brake, which is compared with a case where a voltage between terminals of two electrodes is equal to or higher than a predetermined voltage and lower than the predetermined voltage. A coil and an electronic component that are provided in a non-excitation actuated electromagnetic brake and that include an electronic component having a characteristic of having a low resistance value and a diode that is arranged such that a cathode is located on a side having a higher potential than an anode. The first series circuit is configured by being connected in series, the first series circuit and the diode are connected in parallel, and the electronic component does not conduct when the terminal voltage is lower than a predetermined voltage, and the terminal voltage is It is characterized in that it is connected in series to a coil provided in the non-excitation actuated electromagnetic brake so that it conducts when a predetermined voltage or more is reached.
