To make a diagnosis of door opening/closing performed at a predetermined timing with high accuracy using information of a torque value applied to a door motor during door opening/closing in normal operation.SOLUTION: An elevator control device 40 comprises a door premonitory abnormality detection information holding unit 43, an operation control unit 42 and a diagnostic operation information changing unit 44. The door premonitory abnormality detection information holding unit 43 retains information regarding the floor where a door premonitory abnormality regarding door opening/closing action is detected during normal operation. The operation control unit 42 makes a door opening/closing diagnosis at a preset timing. The diagnostic operation information changing unit 44 reduces the door opening/closing speed for the floor where a door premonitory abnormality is detected at the time of the door opening/closing diagnosis, as well as lowers a threshold value of a torque value applied to a door motor 31 for determining whether there is abnormality in the door opening/closing action.SELECTED DRAWING: Figure 1 【課題】通常運転時のドア開閉中にドアモータにかかったトルク値の情報を用いて、所定のタイミングで実行するドア開閉診断を効率よく高い精度で行う。【解決手段】エレベータ制御装置４０は、ドア軽異常検出情報保持部４３と、運転制御部４２と、診断運転情報変更部４４とを有する。ドア軽異常検出情報保持部４３は、通常運転時にドア開閉動作に関する軽異常が検出された階床の情報を保持する。運転制御部４２は、予め設定されたタイミングで、ドア開閉診断を行う。診断運転情報変更部４４は、軽異常が検出された階床に対しては、ドア開閉診断時に、ドア開閉速度を低速にするとともにドア開閉動作に異常があるか否かを判定するためのドアモータ３１にかかるトルク値の閾値を低くする。【選択図】図１
