Abstract

PURPOSE: To feed-back control speed in a digital system, by generating logical pulse signals by comparing a location level signal at an arbitrary slice level digital controlled.
CONSTITUTION: A location detecting signal s of a load 11 put out from a location signal detector 13 is converted into a location level signal x at a location signal detecting circuit 30, and fed to a location pulse signal detecting circuit 70. A comparator 72 compares a reference voltage level supplied as a digital value and the location level signal x, and puts out logical ON-OFF signals. A program type control sequence controller 100 time counts an interval between pulse signals between two location signal levels obtained as the ON-OFF signals and gains an actual interval, and feeds difference between the interval and a reference interval corresponding to the actual interval to a speed control mode current control circuit 60.
