Abstract
An operating table and a method for an operating table are disclosed. The operating table has an adjustable component, a drive device that adjusts the adjustable component, and a first sensor that detects a position of the adjustable component. The operating table also has a second sensor that detects the position of the adjustable component and a controller that controls the drive device. The controller operates in a first operating mode and a second operating mode. In the first operating mode of the controller, the first sensor is activated and the drive device is energized. In the second operating mode of the controller, the second sensor is activated and the drive device is de-energized The controller changes from the second operating mode to the first operating mode when the second sensor detects a change of the position of the adjustable component.
