Abstract:
An elevator operation control device has a component temperature detecting portion for detecting a temperature of a drive device, and a component-protective operation control portion for restraining an elevator from operating in accordance with the temperature detected by the component temperature detecting portion. Upon detecting a rise in the temperature of the drive device, the component-protective operation control portion changes operation control parameters of the elevator to restrain the elevator from operating and thus stops the rise in the temperature of the drive device before a protection circuit stops the elevator from operating.
