ABSTRACT:
A conventional method for driving a servo-motor is carried out by means of a current feedback loop, using a current sensor and an A/D converter. In this conventional set-up, the number of parts was great, cost reduction was difficult and it was difficult to avoid control errors caused by errors in the precision of the current sensor.
A method for driving a servo-motor of the present invention comprises freely setting the current control response of a servo-motor (4) by changing the time-constant .tau. using a calculation system Ra+Las, which is opposite with respect to the calculation system of the servo-motor (4), and a primary delay element 1/1+.tau.s.
