PURPOSE:To improve the practicability of the digital servo amplifier by measuring the current value of a motor as a digital value and controlling the speed of the motor. CONSTITUTION:The detection output of a DC servomotor 5 is inputted to a speed detector 7 and a current value digitizing device 8. A microcomputer 11 inputs a rotating speed and a current value from the detector 7 and device 8 at a specific sampling period and calculates a control voltage according to an arithmetic program stored in a storage device 10, and the voltage is supplied to the motor 5, whose speed is controlled. |
