PURPOSE: An output control apparatus for position controller is provided to achieve an improved performance of position controller by performing error correction in accordance with the correction value obtained from the difference between the command for the current position and actual position. CONSTITUTION: An apparatus comprises a servo controller(201) for performing arithmetic operation to the position command and outputting an analog voltage and position command pulse; a drive unit(202) for amplifying an analog output voltage from the servo controller and outputting the amplified voltage to a motor(203); and an encoder(204) for detecting, in pulse, the rotation of the motor, and feeding back the detected value to the servo controller. The servo controller includes a command value operator(211) for operating the position command and calculating position data value; a comparator(212) for comparing output value of the command value operator with the output value from the encoder, and calculating the difference for error correction; an amplifier(213) for compensating the output from the comparator with a position loop gain(Kp); a digital-analog converter(214) for converting the output from the amplifier; and a pulse generator(215) for generating a position command pulse by using, as an input, the output from the comparator.
