METHOD FOR MEASURING CURRENT VALUE WHEN DETECTING THAT OBSTACLE GETS CAUGHT IN DOOR, METHOD FOR SETTING THE CURRENT VALUE, AND APPARATUS FOR MEASURING THE CURRENT VALUE

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring a current value when detecting that an obstacle gets caught in a door, which enables the measurement of the current value of a motor for opening/closing when it is detected that the obstacle gets caught in the door, because a predetermined load is applied to the door during a closing operation, a method for setting the current value, and an apparatus for measuring the current value.;SOLUTION: A wire 22 having one end 22a connected to a door 3, and a weight (load part) 23 connected to the other end 22b of the wire 22 and enabling a predetermined load to be applied to the door 3 via the wire 22 are installed in such a manner that the wire 22 is elongated to the utmost in a section in which a closing speed when the door 3 is shifted toward a closed state from an open state becomes constant and that the predetermined load is applied to the door 3 from the weight 23. The door 3 is closed from the open state while a threshold of a current value of a motor 4 for opening/closing during the reversing motion of the door 3 is changed, and the optimum threshold of the current value of the motor 4 for opening/closing during the reversing motion of the door 3 is measured.;COPYRIGHT: (C)2013,JPO&INPIT
