Abstract (en)
There is provided an elevator apparatus that can control a motor power supply relay or the like even if a brake control device fails. To this end, the elevator apparatus includes: a relay having a function of blocking supply of electric power to a motor or a brake of an elevator; a driver that drives the relay; an operation control device that outputs a control signal to the driver; a brake control device that outputs a control signal according to a control signal output from the operation control device in normal time, and outputs a control signal independent of the control signal output from the operation control device in an emergency stop of the elevator; and a switching device that receives as an input the control signal output from the operation control device and the control signal output from the brake control device, and that switches the control signal to be output to the driver from the control signal output from the brake control device to the control signal output from the operation control device when the brake control device fails.
