Abstract
PURPOSE: To eliminate the zero output generated for fault signal disconnection, by applying a false input signal besides the three input signals after fault signal disconnection.
CONSTITUTION: When three input signals I1WI3 are normal, fault signal disconnection switches 2B1W2B3 are connected to the contact (a) side, and switch 6 for false input supply is opend. Input signals I1WI3 are applied to subtractors 41W43 together with output signal ϕ and are sent to adder 3 through limiters 11W13. Limiters output the positive or negative saturation value when their inputs exceed a prescribed range, and output ϕ of adder 3 becomes the intermediate value. When a fault is detected in one of input signals I1WI3, one of switches 2B1W2B3 corresponding to the fault signal is connected to the (b) side, and switch 6 is connected. At this time, the value of a smaller one of normal input signals is output as output ϕ of the adder.
