PROBLEM TO BE SOLVED: To secure safety for the human body in a fence when entering an operation range in the safety fence for confirming a position and an attitude after guiding an end effector up to an objective position by operating a robot from the outside of the safety fence in teaching work of an automatic machine device such as an industrial robot. SOLUTION: An overcurrent protector for driving and an overcurrent protector for teaching are connected in parallel to the front of a driver circuit from a motor. Capacity of the latter is sufficiently reduced more than the former. The protector is switched to the latter in the teaching work, and an operation speed is reduced by a low electric current. Since this automatic machine device is safe by being restrained in uninjuring torque even when touching the robot by mistake, the teaching work can be performed in the safety fence, and efficiency of the teaching work is improved.
