Abstract

PURPOSE:To surely prevent runaway of a carrying section, by outputting an abnormality signal when a carrying speed of the carrying section exceeds a reference value or the ratio of the moving speed of the carrying section to the revolving speed of a motor driving the section is abnormal. CONSTITUTION:A carrying section is driven with a pinion gear 5, which is coupled with a motor 4 via a gear reducer. When a speed reference signal S is applied to the section, carrying section, the motor 4 is turned with a reference speed with known speed control circuits 19-24, and the carrying section is moved with a referenced speed. The speed of the carrying section is detected as a revolving speed of the gear 5, and when this detected value V1 exceeds a specified value Vref, a failure signal (a) is outputted from a comparator 25. If speeds V2, V1 of the motor 5 and the gear 5 do not satisfy a specified relation (failure in a gear reducer), an abnormality signal b is outputted from a comparator 29.
