Image Number 3 for United States Patent #7129668.

An actuator control device includes an electrical control unit for detecting the present positions of output shafts of servo motors, and communicating with control circuits for driving the output shafts of the servo motors to target stop positions on the basis of the present positions thus detected. When it is judged that a present position of one of the output shafts thus receives is abnormal, the electrical control unit corrects the present position and transmits the corrected present position to the appropriate control circuit.
