Apparatus for and method of controlling stepping motor |
摘要 |
An apparatus for controlling a stepping motor used for moving a carriage having a pickup from a first position to a second position, the apparatus having: a calculating device for calculating a moving distance between the first position and the second position; a setting device for setting an acceleration area to accelerate the stepping motor and a deceleration area to decelerate the stepping motor, on the basis of the moving distance; and a driving device for driving the stepping motor by a one-two-phase excitation method until rotation velocity of the stepping motor increases to a predetermined velocity in the acceleration area, driving the stepping motor by a two-phase excitation method after rotation velocity of the stepping motor increases to the predetermined velocity in the acceleration area, driving the stepping motor by the two-phase excitation method until rotation velocity of the stepping motor decreases to the predetermined velocity in the deceleration area, and driving the stepping motor by the one-two-phase excitation method after rotation velocity of the stepping motor decreases to the predetermined velocity in the deceleration area.
