Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/005591
Kind Code:
A1
Abstract:
A motor control device comprises: a means for inputting parameters necessary for controlling a motor, the parameters consisting of the operation start and end positions of an object to be controlled, the maximum rotation speed of the motor, an adding amount of rotation speed, and a subtracting amount of the rotation speed; a means for detecting the position of the object to be controlled; and a means for calculating a deceleration start position from the operation start and end positions, and for, when operating the object to be controlled from the operation start position to the operation end position, continuing to perform an adding operation on a target rotation speed on the basis of the difference between the maximum rotation speed and a current rotation speed and adding amount information and driving, until it is detected that the object to be controlled has reached the deceleration start position, the motor while accelerating so that the motor rotates at the target rotation speed, and for, at a time point when it is detected that the object to be controlled has reached the deceleration start position, starting and continuing to perform an subtracting operation on the target rotation speed on the basis of the difference between the maximum rotation speed and a current rotation speed and subtracting amount information and driving, until it is detected that the object to be controlled has reached the operation end position, the motor while decelerating so that the motor rotates at the target rotation speed.
