The yawing arrangement (1) comprises two or multiple actuators (300), which have a servo motor (310) and an actuating gear (320), and a control unit (200) for controlling the actuators. A monitoring unit (100) is provided, which is constructed and arranged for each of the two or multiple actuators for detecting a motor current. The monitoring device is constructed and arranged to compare the detected motor currents. The monitoring device is constructed and arranged to generate a warning signal corresponding to a result of the comparison of the motor currents. An independent claim is included for a method for moving rotors of a wind turbine corresponding to a wind direction. |
