PROBLEM TO BE SOLVED: To provide an elevator controller and an elevator control method capable of diagnosing braking force of a brake during normal operation which is other than a diagnosis mode, without deterioration of riding comfort felt by passengers in a car.SOLUTION: Before a car (1) starts to travel, a first torque command value is applied to a motor (6) in advance in a same direction of a travel direction of the car. In the state, braking force of a brake (7) is gradually released and the car starts to travel, and matching between a current value of a brake coil and a value of unbalance torque during travel start is checked, for diagnosing braking force of the brake.

    【課題】乗りかご内の乗客の乗り心地を損なうことなく、診断モードでない通常運転時においてもブレーキの制動力を診断することができるエレベータの制御装置およびエレベータの制御方法を得る。【解決手段】乗りかご(1)の走行開始前に、乗りかごの走行方向と同方向に予め第1トルク指令値をモータ(6)に印加させた状態で、ブレーキ(7)の制動力を徐々に開放して乗りかごを走行開始させ、走行開始時のブレーキコイルの電流値とアンバランストルクの値との整合性をチェックすることにより、ブレーキの制動力を診断する。【選択図】図1
