Abstract:

A door control device for an elevator, capable of more accurately measuring the weight of the door of the elevator. The door control device for an elevator is provided with: a torque command generation means for generating a torque command for the door motor for moving the door of the elevator; a torque command storage means for storing the value of a torque command for moving the door at a constant speed; a door-drive-force calculation means for calculating the value of a force applied to the door when the door is moved with acceleration, the calculation being based on the value obtained by subtracting the value of the torque command for moving the door at the constant speed from the value of the torque command for moving the door with the acceleration; and a door weight calculation means for calculating the weight of the door by dividing the value of the force applied to the door when the door is moved with the acceleration by the value of the acceleration of the door when the door is moved with the acceleration.
