Zusammenfassung:	To provide a motor valve control device capable of determining whether a rotor can rotate normally within an appropriate rotation range.SOLUTION: A motor valve control device determines that a rotor cannot rotate normally, when a pulse number (input number Xi) input to a stepping motor from a second direction rotation restriction state Sr2 to a first direction rotation restriction state Sr1 or from the first direction rotation restriction state Sr1 to the second direction rotation restriction state Sr2 is smaller than a design number Xd, or when the input number Xi is larger than an upper limit number Xu that is larger than the design number Xd.SELECTED DRAWING: Figure 17 【課題】ローターが適切な回転範囲で正常に回転できるか否かを判定できる電動弁制御装置を提供する。【解決手段】電動弁制御装置は、第２方向回転規制状態Ｓｒ２から第１方向回転規制状態Ｓｒ１までの間または第１方向回転規制状態Ｓｒ１から第２方向回転規制状態Ｓｒ２の間にステッピングモーターに入力されたパルス数（入力数Ｘｉ）が設計数Ｘｄより小さいときまたは入力数Ｘｉが設計数Ｘｄより大きい上限数Ｘｕより大きいとき、ローターが正常に回転できないと判定する。【選択図】図１７
