Description
Claims (1)
- 인버터 제어에 의해서 운전중인 모터의 자동절체 방법으로서,시스템의 운전중인 모터들 중 어느 한 모터가 과열 등에 의해 트립이 되어 정지될 경우 이 정지된 모터를 파악하면서 다른 운전중인 모터들은 운전을 계속 유지시키는 단계와;상기 정지된 모터를 제외한 나머지 모터들중 순차적으로 정지상태이면서 트립된 상태가 아닌 모터를 검색하는 단계와; 및상기 정지된 상태이면서 트립된 상태가 아닌 모터를 상기 고장이 되어 정지된 모터를 대신하여 시스템에 자동적으로 대체 투입하는 단계를 포함하는 것을 특징으로 하는 인버터 제어에 의해서 운전중인 모터의 자동절체 방법.
