Abstract

PURPOSE:To prevent a device from being stopped due to load fluctuation and line voltage fluctuation, by feeding output voltage and output frequency patterns accommodated to a load, to an induction motor, in consideration of the line voltage fluctuation. CONSTITUTION:So far as a microcomputer 10 is concerned, voltage applied to an inverter section 4 just before starting an induction meter 6 is detected, and after the fluctuation of a commercial AC power source 1 is discriminated, operation is started. Besides, on the micro-computer 10, by the output frequency of a V/F converter circuit 9 and the voltage of the commercial AC power source 1 just before starting, a load state is discriminated. By this method, line voltage fluctuation, overload, and light-weight load are discriminated, and they are converted to V-F patterns accommodated to them, and with the optimum V-F patterns to the load, the induction motor 6 is operated.
