るモータの暴走検出回路。In a feedback automatic control system equipped with a microcomputer that outputs a position command to give a desired response characteristic to a motor that drives a controlled object, the deviation between the position command value output from the microcomputer and the position feedback value is determined. It is equipped with a differentiator that differentiates the absolute value, and a counter that counts the time during which the absolute value of the deviation from the sign of the differential coefficient tends to increase continuously, and when the counted number exceeds a set value, the motor runs out of control. A runaway detection circuit for a motor, characterized in that abnormality processing is performed via the microcomputer.
