The invention is such that a so-called non-excitation operation type electromagnetic brake control device includes a first brake control circuit 201 having a first operation unit 121 that carries out an operation process in accordance with a brake command and a first external switch 141 turned on in accordance with a brake signal generated based on an output signal of the first operation unit 121, a second brake control circuit 202 having a second operation unit 122 that carries out an operation process in accordance with a brake command and a second external switch 142 turned on in accordance with a brake signal generated based on an output signal of the second operation unit 122, a voltage detector 152, and a current detector 153, wherein the first external switch 141 and second external switch 142 are connected in series between a brake power supply 160 and an electromagnetic brake 170. Because of this, even when there is a single failure in one control circuit, an overvoltage, or an overcurrent, the brake can be promptly engaged using the other control circuit, thus improving safety.
