Abstract: A system and a method are provided for damping vertical oscillations of an elevator car hovering at an elevator landing. The system includes a sensor, a controller and an elevator machine connected to a traction sheave. The sensor is adapted to provide a sensor signal indicative of rotation of the traction sheave, wherein the rotation of the traction sheave corresponds to the vertical oscillations of the hovering elevator car. The controller is adapted to provide a control signal based on the sensor signal. The elevator machine is adapted to reduce the vertical oscillations of the hovering elevator car by controlling the rotation of the traction sheave based on the control signal.
