Document Type and Number:
WIPO Patent Application WO/2019/240213
Kind Code:
A1
Abstract:
This motor control device (27) carries out an initialization process for moving a shaft (44) of a valve body (25) toward the origin position (P0), causing the shaft to butt against an end of a movable region, and then updating the origin position. In the initialization process, the motor control device defines a section up to a set position (P4), which has been set before the origin position, as a first section (S1), defines a section between the set position and the origin position as a second section (S2), and sets the rotational torque of a motor to be lower in the second section than in the first section.
