PURPOSE:To drive moving bodies, such as tools, etc., at an appropriate speed, by obtaining gain set signals corresponding to gain selecting signals read out from a memory along with location target values of the moving bodies, from a gain regulator of a servo amplifier. CONSTITUTION:When a moving body is driven from a location target value to the next location target value under a condition where no one-sided load is applied on the moving body, a location target signal of the next location target value and a gain selecting signal are outputted from a memory 1 when an output signal which is to be used for reading out the next target value is added to the memory 1 from a controller 2. The location target signal is converted into an analog value at a DA converter 3 and added to a servo amplifier 4, and then, becomes a servo current after amplification. The servo current operates a servo mechanism 7. When the servo mechanism 7 is operated, a feedback signal corresponding to the operation of the servo mechanism 7 is added to the feedback input terminal of the servo amplifier 4 from a potentiometer 9 in the direction where the servo current becomes 0 (zero). Therefore, the servo mechanism 7 finally stops at a point of time where the servo current becomes 0 (zero). The gain selecting signal has a constant value and this is given to a gain regulator 5.
