Abstract

PURPOSE:To detect rapidly droop-over, overrun, etc., of a control system by using a carry or borrow signal of the intermediate reversible counter counter out of plural connected reversible counters as the interrupt signal for a computer. CONSTITUTION:Carry signal 17 and borrow signal 18 from second-stage reversible counter 21 out of reversible counters 20, 21 and 22 which give position deviation signals to a servo amplifier through digital analogue converter 16 are inputted to computer 19 as interrupt signals. As a result, droop-over and overrun in a carry interrupt can be detected by executing the program of a flow chart shown in the figure. They can be detected in a borrow interrupt also.
