Abstract
PURPOSE:To inhibit unstable condition of a motor by feeding back a value corresponding to variation in the output current of an inverter to a voltage frequency converter determining the output frequency of the inverter. CONSTITUTION:The output of a voltage type inverter device 14 is connected to an induction motor 6 by way of a current transformer 5. The inverter output voltage is lowered with a current transformer 9 and inputted into a voltage control circuit 10 with a command signal of a frequency setting device 7 to form a control signal to control a pulse width modulation control circuit 11. A load current detection signal of the current transformer 5 is inputted into a phase inverter 12 and a selector 27. When the detection signal is small, the signal inverted in the phase with the phase inverter 12 is inputted into an arithmetic circuit 13 with a command signal from an acceleration/deceleration limit circuit 8 through the selector 27, formed as a frequency control signal with a voltage-frequency converter 15 and then inputted into a pulse width modulation controlling circuit 11.
