Abstract

PURPOSE: To reduce a delay time and its change after commanding the start and to cut material of a fixed length precisely by feeding current, which produces a torque less than the starting torque of the cutting machine drum, before the starting.
CONSTITUTION: An arithmetic and control unit 19 that performs an operation of the cutting machine start timing is provided to deliver a contact output 21 that determines the start timing, speed reference signal 23 and contact output 22 that determines the timing of current reference signal output 24. The current reference signal 24 is added to an output signal of the speed control amplifier 9 by the adder 25, and is fed to the current control amplifier 15. Here, the value of current reference signal 24 is made less than the frictional current of the cutting machine. By this way, the motor starts and turns by backlash with the shaft of drum 2, but the motor is stopped at the time because a torque required to turn the drum 2 is not produced, and it can respond quickly to the next starting.
