Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a disconnection detection apparatus of a sinusoidal wave signal.SOLUTION: The apparatus of the present invention converts a first sinusoidal wave and a second sinusoidal wave into absolute values, respectively, and determines that disconnection is present when a value of the first sinusoidal wave is less than a first comparison value that is greater than a minimum value and a value of the second sinusoidal wave is less than a second comparison value that is less than a maximum value.SELECTED DRAWING: Figure 3 【課題】正弦波信号の断線検出装置を開示する。【解決手段】本発明の装置は、第１の正弦波と第２の正弦波をそれぞれ絶対値に変換し、第１の正弦波の値が最小値より大きい第１の比較値より小さく、第２の正弦波の値が最大値より小さい第２の比較値より小さい場合には、断線であると決定する。【選択図】図３
