<P>PROBLEM TO BE SOLVED: To provide an elevator door control device that is capable of setting a proper torque threshold for each floor even when the memory capacity is small. <P>SOLUTION: The elevator door control device includes: a drive control means which outputs a torque command value to a motor so that rotation speed of the motor for driving the door of the elevator follows a speed command value corresponding to a position in the opening and closing direction of the door; a memory means which stores a plurality of reference torque thresholds corresponding to respective positions in the opening and closing directions of the door as the reference when determining torque threshold obtained by adding an offset value to the torque command value in order to determine that torque of the motor is excessive; a calculation means which calculates a value corresponding to the ratio of the torque command value to a reference torque command value corresponding to the reference torque threshold with respect to the respective positions in the opening and closing direction of the door for each floor; and a torque threshold calculation means which determines a difference obtained by subtracting the offset value from the reference torque threshold corresponding to positions in the opening and closing directions of the door, and defines a value obtained by adding the offset value to a value obtained by multiplying the ratio by the difference as the torque threshold corresponding to the positions in the opening and closing directions of the door for each floor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
