The invention provides an elevator control device and an abnormality diagnosis method. Whether a smoothing capacitor of a power supply of a driving motor is in an abnormal state is determined. An elevator control device according to an embodiment includes a power source that supplies power to at least one of a motor that drives the opening and closing of a car door and a motor that drives the lifting of a car, and determines an abnormal state of a smoothing capacitor disposed in the power source. The elevator control device is provided with an abnormality judgment part, and the abnormality judgment part extracts information related to the amplitude of ripple noise of a power supply from waveform data representing time series change of motor torque, and judges the abnormal state of a smoothing capacitor of the power supply configured to drive the motor.
本发明提供一种电梯控制装置以及异常诊断方法,判断驱动马达的电源的平滑电容器是否处于异常状态。实施方式的电梯控制装置具备向对轿厢门进行开闭驱动的马达或者对轿厢的升降进行驱动的马达的至少一方供给电力的电源,判断配置于电源的平滑电容器的异常状态。电梯控制装置具有异常判断部,该异常判断部从表示马达扭矩的时间序列变化的波形数据中提取与电源的纹波噪声的振幅相关的信息,判断配置于驱动马达的电源的平滑电容器的异常状态。
