Abstract

PURPOSE: To widen the control coverage of cutting length in a running cutter device used in a steel bar mill etc. by, at the initial time of starting, accelerating at the max. torque and by, under the process of acceleration, changing the acceleration rate to values at which the acceleration current corresponds to a certain specified cutting torque.
CONSTITUTION: A control circuit 10A is provided for change-over of input to the current limitation setting circuit 26. This change-over control circuit 10A is to change-over the initial acceleration setting device 27A to the cutting acceleration setting device 27, and thereby the initial acceleration rate α0 to the cutting acceleration rate α. By this change-over control, the angle and time of acceleration are minimized to the limit value of capacity of the drive motor, and thereby the limitation given by the cutting torque required can be minimized and the control coverage of cutting length, widen.
