구출운전시 인버터 제어방법이 개시된다. 본 발명의 방법은, 전동기에 구속전압을 인가하고, 전동기의 기동 이후 소정의 초기 기동구간이 경과하면, 구속전압을 소정 레벨만큼 점진적으로 낮추고, 전동기의 누적된 위치변화량이 소정 레벨에 도달한 경우, 고중량에 따라 구출운전을 수행한다.
Disclosed is a method for controlling an inverter during a rescue operation which reduces energy consumption and increases riding quality by reducing the number of driving and a driving distance for detecting a driving direction. The method comprises the following steps of: applying a holding voltage to a motor; gradually lowering the holding voltage by a predetermined level when a predetermined initial operation section elapses after starting the motor; and performing a rescue operation according to a high load when a cumulative position change amount of the motor reaches a predetermined level.
