Abstract
PURPOSE:To carry out various V/F patterns by selecting on ROM which stores the V/F patterns by a selector switch. CONSTITUTION:A frequency command from a frequency instruction circuit 1 is inputted to an ROM5 of a memory circuit simultaneously to a frequency control circuit 2. The ROM5 stores in advance various V/F patterns, and the output of the ROM of the address selected by the selector switch 6 connected thereto is inputted to a voltage control circuit 4. Since this ROM4 can stores various patterns, the pattern can be selected suitably to meet the produced torque necessary for an induction motor as a load by a simple operation of selecting an address by the selector switch 6.
