摘要:
An elevator apparatus performing proper braking control of a car according to a detected content of a failure, and including: a semiconductor switch connected in series to a brake coil, for varying current flowing through the brake coil; an interruption switch connected in series to the brake coil and the semiconductor switch and capable of interrupting current flowing through the brake coil; a braking force control processing mechanism controlling an amount of current flowing through the semiconductor switch according to deceleration of the car when the car stops; a failure detection section detecting failure in the braking force control processing mechanism; a critical event detection mechanism detecting a critical event requiring an urgent stop of the car based on a state detection signal; and a brake power supply interrupting mechanism turning the interruption switch OFF to apply braking when the failure and the critical event is detected.
