A device for controlled operation of an elevator, where, when the elevator in a traveling motion stops at the nearest floor in controlled operation due to earthquake or strong wind, the device causes the natural vibration frequency of lateral sway of a rope not to resonate with the natural vibration frequency of the building, thereby preventing an increase in lateral sway of the rope. In the controlled operation, the device causes the elevator in a traveling motion to stop at the nearest floor when sway of the building by earthquake, strong wind, or other reasons is detected or, alternatively, causes the elevator passing a rapid zone to make an emergency stop and then move at low speed to the nearest floor. The device has rope resonance check means that compares both the natural frequencyof the rope in lateral sway and the natural frequency of the building and stops a car at a non-resonant position so that the natural frequency of the rope in the lateral sway does not resonate with the natural frequency of the building.
