To detect dynamic torque by means of software without adding new equipment for monitoring the dynamic torque and to enable periodic and automatic measurement of dynamic torque without applying a load to elevator equipment.SOLUTION: When there is no user in an elevator car, the car is held by a brake, and, in this state, hoisting machine torque is applied in a counterweight direction to perform slow-speed traveling control. The hoisting machine torque when a hoisting machine is rotated beyond static holding torque of the brake is detected. Dynamic torque of the hoisting machine is calculated by adding balance torque for compensating for load unbalance, to the detected hoisting machine torque. The braking force of the hoisting machine brake is diagnosed by whether the calculated dynamic torque exceeds a reference value or not.SELECTED DRAWING: Figure 2

    【課題】動トルク監視用の新たな機器を付加することなくソフトウェアで動トルクを検出でき、エレベータ機器に負荷をかけずに定期的に自動測定可能にする。【解決手段】乗りかご内に利用者が居ないとき、ブレーキで乗りかごを保持し、この状態で吊り合いおもり方向に巻上機トルクを印加して微速走行制御を実施し、ブレーキの静保持トルクを超えて巻上機が回転した際の巻上機トルクを検出し、検出された巻上機トルクに荷重アンバランスを補償する吊り合いトルクを加算して巻上機の動トルクを算出し、算出された動トルクが基準値を超えたか否かにより巻上機ブレーキの制動力を診断する。【選択図】図2
