Title:
OPENING AND CLOSING CONTROLLER
Document Type and Number:
Japanese Patent JP3687532
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an opening and closing controller quickly and effectively functioning as an insertion prevention after the starting of a motor and quickly accelerating the motor without causing any wrong decision on an insertion.
SOLUTION: An operation means (controlling circuit ID for obtaining a differential value Δ1 for motor load used for a decision on the insertion by amplifying at an amplification factor K is provided, the amplification factor K is made to become zero directly after the starting of the motor, and the decision is made without making any wrong decision on the insertion from directly after the starting of the motor without providing for a long soft starting period by having such a constitution that the amplification factor is gradually increased after the starting of the motor.
