The invention provides a diagnosis device of a passenger conveyor, which can effectively perform diagnosis while ensuring the accuracy of diagnosis of brake performance. The diagnostic device for the passenger conveyor diagnoses the brake performance of the passenger conveyor, and is provided with an operation control part (18) for controlling a brake (17) of a speed reducer (10) and a motor (9) for supplying power to the speed reducer (10), the brake (17) is kept in a braking state through the operation control part (18), and the motor (9) is driven by the speed reducer (10) while the braking state of the brake (17) is kept. Then, the motor (9) generates a torque set in accordance with a value of a braking distance that is a reference for brake performance, and then the presence or absence of an abnormality in the brake performance is determined on the basis of the presence or absence of rotation of the rotating shaft of the speed reducer (10).
本发明提供乘客输送机的诊断装置,能在确保制动器性能的诊断的精度的同时,有效率地进行诊断。该乘客输送机的诊断装置诊断乘客输送机的制动器性能,具有控制减速机(10)所具备的制动器(17)和对减速机(10)给予动力的电动机(9)的运转控制部(18),通过运转控制部(18),在保持制动器(17)的制动状态的同时,使电动机(9)产生与成为制动器性能的基准的制动距离的值对应地设定的转矩,然后,基于减速机(10)的旋转轴的旋转的有无来判定制动器性能的异常的有无。
