Abstract

PURPOSE: To enable one to start the motor during a reverse operation by providing the second means which sets the reversal output frequency until the starting command of the inverter is fed and by providing the third means which selects the first means that sets the stationary operation output frequency after input of the starting command.
CONSTITUTION: In stopping the motor 14, the switches 51 and 52 are "off" and "on" respectively by the switching circuit 53, the reversal frequency N12 is selected as a speed command input. When a starting command S is fed to the switching circuit 53, the switches 51 and 52 are turned "on" and "off" respectively, the speed command input is changed to the stationary operation frequency N10 step by step. Therefore the output of the limiter 50 begins to change from N12 to N10 in the form of ramp function, the whole inverter circuit which consists of the control circuit 11 and inverter 13 starts at the voltage and frequency specified by the output command of the limiter 50.
