ABSTRACT:
A servo amplifier circuit, wherein a target value is obtained based on a detected output voltage of the servo amplifier circuit, and the absolute value of the target value is amplified, and then is inverted only when the target value is negative. An offset adusting is carried out by obtaining a forward offset as an output voltage of the servo amplifier circuit without an inversion and an adjustment when the target value is set to zero, and a reverse offset as an output voltage of the servo amplifier circuit with an inversion and without an adjustment when the target value is set to zero, and by obtaining an offset adjusting value using the forward offset and the reverse offset. The absolute value is modified using the offset adjusting value.
