Abstract
A door controller and a method for inputting or adjusting one or more reference positions into the door controller have the controller connected to a door drive for moving a door and utilize a pulse encoder for monitoring a position of the door and a non-volatile memory for storing the reference position. In a learning mode a control force signal to the drive is reduced. Then the door is moved to the reference position and finally the reference position as recorded by the pulse encoder is registered in the memory of the controller.
