PURPOSE:To manufacture a digital servo-controller by a simple circuit constitution wherein a digital circuit is made as a center by arithmetically operating an output value to a motor drive means by outputs from a digital arithmetic command-value memory means, a present-speed memory means and a constant memory means. CONSTITUTION:Speed feedback arithmetic operation and positional feedback arithmetic operation are conducted in a position and seed servo-arithmetic means 1, and a current command value (di) is memorized to a digital arithmetic command-value memory means 7. On the other hand, the speed of revolution Vf of a motor from a speed detecting means 6 is memorized to a present-speed memory means 10, and each constant of the motor 4 is memorized to a constant memory means 9. A control arithmetic means 8 arithmetically operates a current command value alpha0 from outputs from the memory means 7, 9, 10, and outputs it to a motor drive means 3. Accordingly, an extremely simple digital servo- controller, which centers a digital circuit and cost thereof is low, can be acquired. |
