Abstract

PURPOSE:To improve the response of a slip frequency control device by controlling the output frequency of a frequency converter with the output sums of the slip frequency control amplifier and a motor speed detector, thereby reducing the displacement of the slip frequency at a transient time. CONSTITUTION:Motor revolution frequency FM is added to the output of a slip frequency control amplifier 8 through a frequency converter 9 by an adder 11, and an output frequency FINV of the frequency converter 10 is controlled with the sum of the outputs. Thus, the converter 10 is effectively associated with the output of the amplifier 8 so that the range of the slip frequency FS may be controlled, for example, with the range of 0-6Hz. The displacement of the slip frequency FS is improved even at transient time such as abrupt change of the slip frequency command FSR, and the displacement of the output frequency FINV can be decreased.
