Abstract
An elevator control device is provided with a cooling fan, a component to be cooled that is used for drive control of a hoisting machine and is cooled by the cooling fan, a temperature sensor for measuring the temperature of the component to be cooled, and a control device for controlling the entire elevator apparatus. The control device includes a control unit and a cooling effect diagnosis unit. The control unit drives and controls the hoisting machine to perform a normal operation and an efficient heat generation operation in which the component to be cooled is heated to a temperature higher than the temperature during the normal operation for the diagnosis. The cooling effect diagnosis unit diagnoses the cooling effect of the component to be cooled on the basis of the temperature measurement value obtained from the temperature sensor during the efficient heat generation operation.
