時ドルーピング補正回路。The mill motor that drives the work rolls of the stand that makes up the tandem rolling mill is added to the speed control device for the purpose of absorbing load fluctuations without feeding back the detected load current value based on the stand speed command. In a drooping circuit that provides a drooping characteristic, a differential calculator is used to differentiate an acceleration/deceleration command and calculate a current value corresponding to the acceleration/deceleration variation, and a differential calculator that subtracts the detected load current value from the output signal of the differential calculator and calculates this difference. A drooping correction circuit for accelerating and decelerating a tandem rolling mill, comprising a drooping signal generator that multiplies the value by a drooping set value and outputs a drooping signal.
