To control a stepping motor so as to reduce step error in individual units of a motor-driven valve.SOLUTION: A motor-driven control device 200 for controlling a motor-driven valve having a stepping motor for rotating a rotor by driving current applied according to an exciting pattern corresponding to step, and a mechanism for changing a valve opening by rotating motion of the rotor includes: an offset value storage portion 222 for storing an offset value of a step number determined in individual units of the motor-driven valve; a receiving portion 210 receiving a step movement command; a rotation control portion 218 correcting the step number successively switched on the basis of the step movement command on the basis of the offset value, and specifying an exciting pattern corresponding to the corrected step number; and a rotation instructing portion 214 applying driving current to the stepping motor according to the specified exciting pattern.SELECTED DRAWING: Figure 14

    【課題】電動弁の個体毎のステップ誤差を減ずるようにステッピングモータを制御する。【解決手段】電動弁制御装置200は、ステップに対応する励磁パターンによって印加される駆動電流によってロータを回転させるステッピングモータと、ロータの回転運動によって弁開度を変化させる機構とを有する電動弁を制御する電動弁制御装置であって、電動弁の個体毎に設定されるステップ番号のオフセット値を記憶するオフセット値記憶部222と、ステップ移動コマンドを受信する受信部210と、ステップ移動コマンドに基づいて順次切り替えられるステップ番号をオフセット値に基づいて補正し、補正されたステップ番号に対応する励磁パターンを特定する回転制御部218と、特定された励磁パターンによってステッピングモータに駆動電流を印加する回転指示部214と、を備える。【選択図】図14
