<P>PROBLEM TO BE SOLVED: To provide an electromagnetic brake control device capable of suppressing the heat generation of electromagnetic brakes of non-excitation operation types possessed by servo motors, in the servo motors which drive arms or the like of an articulated robot. <P>SOLUTION: The motors 21 to 26 for driving drive shafts are arranged at respective joints of the articulated robot, and a CPU 30 controls the braking of the drive shafts by the electromagnetic brakes 21b to 26b of the non-excitation operation types possessed by the respective motors 21 to 26. In a period that the braking of the drive shafts is released, the CPU 30 maintains a state that the braking of the drive shafts is released while executing on/off-control for repeatedly turning on and off the application of voltages to excitation coils 21c to 26c of the electromagnetic brakes 21b to 26b. The CPU 30 maintains the on-state of the voltage application over a prescribed period of time in an initial stage of a period that the braking of the drive shafts is released. <P>COPYRIGHT: (C)2013,JPO&INPIT |
