<P>PROBLEM TO BE SOLVED: To provide a controller for an elevator door in which a memory capacity required to precisely detect an abnormality of a torque command at each floor can be made small. <P>SOLUTION: The controller for the elevator door includes: a first storage part 25 for storing reference torque command patterns for calculating an abnormality detection torque pattern at a reference floor on the basis of the pattern of the torque command to a motor for opening and closing an elevator door when the elevator door is opened and closed at the reference floor; a second storage part 26 for dividing the pattern of the torque command into the pattern in an acceleration section in a fixed speed section and in a deceleration section when the elevator door is opened and closed at each floor and storing at least one of a peak value of the torque command in each section at each floor and a switch position in each section at each floor as correction data; and a generation part 27 for comparing the correction data at the reference floor with those at the floors other than the reference floor in each section and generating the reference torque command pattern for calculating abnormality detection torque patterns at the floors other than the reference floor in each section by using the reference torque order pattern at the reference floor in each section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
