PROBLEM TO BE SOLVED: To prevent resetting in error while an elevator is running when the elevator is started again by resetting based on remote control after a slight elevator failure is generated so as to improve safety of a passenger. SOLUTION: If a slight failure is generated in a certain elevator in a building, a maintenance worker in an elevator maintenance company operates an operation unit 9 in a central monitoring device 8 so that a host CPU 10 sends a reset command to a main controller 1 concerning the failure via a remote controller 7. A speed control circuit 3, which inputs a speed detection signal from a drive motor 13, outputs a reset command input enabling signal to a reset command input enabling unit 12 when an elevator speed is zero, that is, when running of the elevator is stopped. When the elevator speed is not zero, that is, when the elevator is run, the speed control circuit 3 outputs a reset command input inhibiting signal to the reset command input enabling unit 12. |
