Actuator controller and a method for controlling such an actuator controller

An actuator controller comprises:

• an actuator body which is to be driven in a predetermined driven range and is equipped with a location sensor for outputting a positional signal depending upon a driven position within said driven range;
• an actuator driving unit for receiving from outside a signal for driving the actuator body to said driven position in the form of an instruction signal of a predetermined bit count, receiving said positional signal from the actuator body and driving the actuator body based on the instruction signal and the positional signal;
• and
• a controller body for outputting said instruction signal to the actuator driving unit, receiving the positional signal from the actuator body, and controlling the driven position of the actuator body,
• wherein said controller body comprises an instructing signal outputting zone configured to outputting, as said instruction signal, a position instructing signal for instructing the driven position of the actuator body according to a bid, excluding arbitrary two bits among said predetermined bit counts, an normal direction forcedly driving signal for instructing a normal direction forcedly driving to drive the actuator body in a predetermined direction with one of said arbitrary two bits, and a reverse direction forcedly driving signal for instructing a reverse direction forcedly driving to drive the actuator body in a direction reverse to said predetermined direction with the other arbitrary bit.
