According to the invention, the stepping motor is controlled, so that the step error of each individual of the electrically operated valve is reduced. A motorized valve control device controls a motorized valve provided with a stepping motor for rotating a rotor by a drive current applied in accordance with an excitation pattern corresponding to a step, and a mechanism for changing a valve opening degree by the rotational motion of the rotor. The electrically operated valve control device includes: an offset value storage unit that stores an offset value of a step number set for each individual electrically operated valve; a receiving unit that receives a step movement command; a rotation control unit that, on the basis of the offset value, corrects step numbers that are sequentially switched on the basis of the step movement command, and specifies an excitation pattern corresponding to the corrected step numbers; and a rotation instruction unit that applies a drive current to the stepping motor in accordance with the determined excitation pattern.
本发明对步进电机进行控制,以减少电动阀的每个个体的步阶误差。电动阀控制装置对电动阀进行控制,该电动阀具有:步进电机,其通过根据步阶所对应的励磁模式施加的驱动电流来使转子旋转,以及机构,其通过转子的旋转运动使阀开度变化;该电动阀控制装置包括:偏置值存储部,其存储针对电动阀的每个个体设定的步阶编号的偏置值;接收部,其接收步阶移动命令;旋转控制部,其基于偏置值,对基于步阶移动命令依次切换的步阶编号进行修正,并确定被修正的步阶编号所对应的励磁模式;以及旋转指示部,其根据被确定的励磁模式向步进电机施加驱动电流。
