材の張力制御装置。 A device for controlling the tension when a rolled material that has been rolled or has been rolled in a rolling mill is unwound from a reel or wound up on a reel, and includes a tensioner that detects the tension of the material to be rolled between the rolling mill and the reel. a tension meter, a pulse generator that detects the rotation speed of the reel, a current detector that detects the current signal of the motor that drives the reel, and a current compensation command value that samples the tension signal from the tension meter. a high-speed arithmetic unit that calculates the motor; and a speed control means that controls the rotational speed of the motor while compensating the current command value based on the current compensation command value output from the high-speed arithmetic unit and the feedback load current signal. A tension control device for a rolled material, comprising:
