Document Type and Number:
Japanese Patent JP6720916
Kind Code:
B2
Abstract:
To appropriately update a parameter which is used for determining compensation torque to cancel unbalance torque.SOLUTION: Elevator control devices 10, 20 are provided with: a speed control unit 12 that determines a torque command value of a motor 5 on the basis of a difference between a command value and a detected value of an elevator speed; a compensation unit 16 that determines compensation torque as a function of an output of a load detector 41 provided to a car 1, and adds the compensation torque to the torque command value; a motor control unit 14 that controls the motor 5 on the basis of a total torque command value obtained by adding the compensation torque to the torque command value; a storage unit 18 that stores log data of an elevator operation; and a parameter calculation unit 23 that updates a function parameter by using the log data. Each of data samples included in the log data includes an output of the load detector 41 immediately before releasing of a brake 7 that has stopped the car 1, and a torque command value immediately before fastening of the brake 7 when the car 1 lands.SELECTED DRAWING: Figure 1
