Abstract:
A method for adjusting a pivotally mounted rotor blade of a wind energy converter includes controlling a first drive and a second drive to collectively turn the rotor blade into an operating position; detecting whether a failure of the first drive has occurred; activating, when the failure of the first drive has occurred, a first activatable lockout connected to the rotor blade, which prevents turning of the rotor blade into the operating position while allowing turning of the rotor blade into a feathered position; and controlling, when the failure of the first drive has occurred, the second drive to turn the rotor blade into the feathered position.
