Abstract (en)
Provided is an elevator control device having a learning function, with enhanced reliability of the result of learning and high performance. An elevator control device for optimizing variable-speed driving includes: a learning function section for updating running control parameters based on a result of identification of running state quantities during a normal operation after an elevator is installed; and a learning-function check section for performing one of stop of elevator service and rated running using predetermined running control parameters when the running control parameters obtained by the learning function section are out of allowable ranges of the running control parameters, which are estimated from allowable fluctuation rates of basic apparatus specification values of the elevator, and for determining that the learning function section is normal when the running control parameters are within the allowable ranges of the running control parameters.
