Beschreibung
Zusammenfassung:	A motor operated valve control device (200) controls a motor operated valve (1) including a stepping motor (3) for rotating a rotor (60) by a driving current applied in accordance with an excitation pattern associated with a step, and a mechanism (109) for changing a valve opening degree by rotational movement of the rotor (60). The motor operated valve control device (200) includes an offset value storage unit 222 that stores a step number offset value set for each individual motor operated valve (1), a reception unit (210) that receives a step movement command, a rotation controlling unit (218) that corrects a step number, which is sequentially switched on the basis of the step movement command, on the basis of the step number offset value, and identifies an excitation pattern associated with the corrected step number, and a rotation instructing unit (214) that applies a driving current to the stepping motor (3) in accordance with the identified excitation pattern.
