Abstract

PURPOSE:To rotate a servo motor in a command rpm, by automatically compensating the offset voltage generating intrinsically in a control device of the motor. CONSTITUTION:In a speed operation section 6 the positional deviation or speed command pulse of a driven body calculated by a deviation calculation section 5 is inputted through a position-speed command calculation section 7 and a speed command is outputted to a D/A conversion section 8. The D/A conversion section 8 converts this speed command into analogue data (voltage), which will be supplied to a servo motor 1 through a servo amplifier 9. The servo motor 1 then rotates in specified rpm. At a position differentiation section 10 the actual speed of the servo motor 1 is calculated and outputted into a corrected value calculation section 11. The corrected value calculation section 11 outputs the difference between the speed command and the actual speed as a corrected value into the speed operation section 6. In this way, since the corrected value outputted from the corrected value calculation section 11 corrects the offset voltage that generates intrinsically with the D/A conversion section 8 and the servo amplifier 9, the servo motor 1 will be caused to rotate in accurate revolutions.
