PROBLEM TO BE SOLVED: To provide an elevator control device with high quietness and control method, which can suppress impact generated at the time of diagnosing so as to diagnose braking capability of a brake device 6 while suppressing noise generated by the impact.SOLUTION: An elevator car 1 arranged in a hoistway of an elevator is gradually released from friction force by a brake device 6, from a state where the car is held still by the brake device 6. Thereby timing ts, at which a motor of a hoisting machine 2 is started to rotate by unbalance torque between the elevator car 1 and a balance weight 5, is detected and a time or a rotation angle as motor state information at timing at which the motor reaches a rotation angle or a time as set timing is detected from the timing ts at which the motor is started to rotate. By comparing the motor state information with a determination threshold, braking capability of the brake device 6 is determined.SELECTED DRAWING: Figure 11
【課題】診断時に発生する衝撃を抑えることで、衝撃によって発生する騒音を抑えつつブレーキ装置6の制動能力を診断できる静粛性の高いエレベータ制御装置及び制御方法を提供する。【解決手段】エレベータの昇降路内に配置されたかご1を、ブレーキ装置6によって静止保持されている状態から、ブレーキ装置6による摩擦力を徐々に解放させる。これにより、巻上機2のモータがかご1と釣合おもり5とのアンバランストルクにより回転開始した時点tsを検出し、この回転開始した時点tsから設定タイミングとしての回転角又は時間などに達した時点のモータ状態情報である時間又は回転角などを検出し、このモータ状態情報を判定閾値と比較することによりブレーキ装置6の制動能力を判定する。【選択図】図11
