Abstract (en)

[origin: EP2565142A1] There is provided an elevator door control device capable of measuring the weight of an elevator door more correctly. For this purpose, the control device has a configuration including a torque instruction issuing means for issuing torque instructions to a door motor for moving the elevator door, a torque instruction storing means for storing the value of torque instruction at the time when the door is moved at a fixed speed, a door driving force calculating means for calculating the value of the force applied to the door when the door is moved while being accelerated, based on a value obtained by subtracting the value of torque instruction at the time when the door is moved at the fixed speed from the value of torque instruction at the time when the door is moved while being accelerated, and a door weight calculating means for calculating the weight of the door by dividing the value of the force applied to the door when the door is moved while being accelerated by the value of the acceleration of the door at the time when the door is moved while being accelerated.
