Abstract: PURPOSE: To enable a protection of the induction motor from any phase defect, by means of  penetrating a connection wire, which is connected across any two phases of the three-phase AC  power source through a resistor, through the current detector unit inserted into the rest one phase.   
     CONSTITUTION: In a case with a SCR switching device 2a causing a fault and only U-phase  becoming defective, only in V-phase and W-phase flows a motor current of single phase with the  current returning to flow in a current transformer 5b, 5c and only a microcurrent returning to flow  in a current transformer 5a, causing a phase defect detecting relay circuit 5d to work as assumed  a state of phase defect. And in a case with a device 2b only causing a fault, the same operation  will be made as the above described. However, when the both devices come to be in a state of  fault with all phases being defective, a microcurrent flows in a circuit comprising a resistor 6 and  a connection wire 7a, 7b, though with the current returning to flow in the current transformers 5a  to 5c for the connection point at a, b, a prescribed number of turns being wound on the current  transformer 5b or the connection wire 7b provides a bigger number of ampere turns as compared  with the other current transformers, causing the circuit 5d to work. In this way, the induction  motor can be protected from any phase defect.

Abstract: PURPOSE:To obtain easy and stable rolling by performing a compensatory calculation so that an interstand tension and a looper angle do not interfere to each other and modifying a driving torque of a looper and a driving speed of rolling rolls in the upstream. CONSTITUTION:A sheet width deviation DELTAW is found based on a sheet width detection value W detected by a sheet width detector 6 in the outlet side of the final stand and a target sheet width value W0 and the deviation DELTAW is converted into a tension target value changing amount DELTAsigma by a sheet width controller 17. On the other hand, an angle deviation is found based on an angle detection value theta detected by an angle detector 6 and an angle target value theta0 and is converted into a rolling roll speed target value changing amount DELTAVr by a height controller 13. Both the tension target value and the speed target value changing amounts are calculated by a compensatory calculation based on a transfer function matrix by a compensator 19. A factor of the tension target value changing amount and a factor of the speed target value changing amount as a looper driving torque correction amount DELTAtau and a speed correction amount DELTAV are outputted to a toque controller 9 and speed controller 14, respectively. Thus, a driving torque tau of a looper 5 and a roll driving speed V are adjusted.
