To restrict a reduction in the life of a power source, resulting from a brake torque inspection.SOLUTION: An elevator control device according to an embodiment includes a power source that supplies electric power to a motor that drives lifting/lowering of a car of an elevator device. The power source performs a switching operation at a first frequency when a car for carrying a user is lifted/lowered, and performs a switching operation at a second frequency lower than the first frequency when the car is lifted/lowered during brake torque measurement of a brake that restricts rotation of a motor.SELECTED DRAWING: Figure 10

    【課題】ブレーキトルク検査に起因する電源の寿命低減を抑制する。【解決手段】実施形態に係るエレベータ制御装置は、エレベータ装置の乗りかごの昇降を駆動するモータに電力を供給する電源を備える。電源は、利用者を運搬するための乗りかごの昇降運行時には第1周波数でスイッチング動作し、モータの回転を抑制するブレーキのブレーキトルク計測時における乗りかごの昇降運行時には、第1周波数より低い第2周波数でスイッチング動作する。【選択図】図10
