Abstract

PURPOSE: To eliminate dead time and enable minute control of speed, by providing a time discrimination circuit for applying a main circuit opening instruction when change-over time between power running and regenerative braking is not shorter than a set time but for applying a slip sign change instruction when the change-over time is shorter than the set time.
CONSTITUTION: The time discrimination circuit 3 measures change-over time from the cutting-off of a power running instruction 1 to the application of a regenerative braking instruction 2 or change-over time from the cutting-off of the regenerative braking instruction 2 to the application of the power running instruction 1. When the change- over time is not shorter than the set time, a main circuit opening instruction 4 is applied to open the main circuit of a variable voltage and frequency inverter. When the change-over time is shorter than the set time, the slip sign change instruction 5 is applied to change only a slip sign.
