ることを特徴とする電動機制御装置。 a speed detection means for detecting the speed of an electric motor that drives a conveyance roll that conveys paper; a tension detection means for detecting the tension of the paper between the conveyance rolls; a current detection means for detecting a current of the electric motor; An electric motor control device comprising a speed control means for controlling the speed of the electric motor based on an output signal from the detection means, and a tension control means for controlling the tension of the electric motor based on an output signal from the tension detection means. ,
Paper breakage occurs between the conveyance roll driven by the electric motor controlled by the speed control means and the conveyance roll provided downstream of the conveyance roll and driven by the electric motor controlled by the tension control means. A reference signal correction means is provided for correcting a reference signal of the speed control means based on an output signal from the tension detection means or the current detection means when such a change occurs, thereby suppressing torque fluctuation of the preceding conveyance roll. An electric motor control device characterized by:
