Zusammenfassung:	A wind turbine (10) is provided. The turbine includes a hub (16), at least one blade (18) coupled to the hub, a wind turbine controller (60), and a pitch controller (40) coupled to the at least one blade and to the wind turbine controller. The pitch controller (40) is configured to establish communication with the wind turbine controller, detect a loss of communication with the wind turbine controller, wherein after a loss of communication is detected. The pitch controller (40) is further configured to wait a first predetermined amount of time for the communication to be restored, independently pitch the at least one blade to a predetermined position, wait a second predetermined amount of time for the communication to be restored, and maintain the at least one blade in the predetermined position until a rotation of the at least one blade stops.
