Claims (4)
- 마이컴이 인버터 드라이버에 PWM신호를 전송하는 단계;
상기 마이컴이 상기 PWM신호 전송 후 상기 인버터 드라이버로부터 PWM신호에 대한 피드백 신호를 전송받는 단계;
상기 마이컴이 상기 피드백 신호로부터 PWM신호선의 오조립 여부를 판단하는 단계로서,
상기 마이컴은 상기 피드백 신호에 포함된 PWM신호의 상승 에지(rising edge)를 검출하여 설정시간 동안 상기 PWM신호를 카운트한 결과를 통해 상기 PWM신호선의 오조립 여부를 판단하는 단계; 및
상기 마이컴이 상기 PWM신호를 카운트한 결과, 설정시간 동안 상기 PWM신호가 검출되지 않으면 상기 PWM신호선이 오조립된 것으로 판단하여, 디스플레이부에 PWM 신호선 오조립을 표시하는 단계;를 포함하되,
상기 마이컴은 상기 인버터 드라이버로부터 PWM신호에 대한 피드백 신호가 전송되지 않으면 압축기 고장인 것으로 판단하고, 디스플레이부에 압축기 고장을 표시하는 것을 특징으로 하는 인버터 드라이버의 자가 진단 방법. - 삭제
