Abstract (en)
[origin: EP2246285A1] In an elevator apparatus, a braking control portion includes: first and second braking control computing portions; a braking control shared memory portion that stores shared data for the first and second braking control computing portions; and a braking control communicating portion that performs transmitting and receiving of signals to and from a hoisting machine control communicating portion. The first and second braking control computing portions compare input signals and computational results with each other by means of the braking control shared memory portion, and also output a failure detection signal from the braking control communicating portion if a compared result exceeds a predetermined range.
