Abstract:
A method for operating a device to vary a blade setting angle on a rotor blade of a wind power plant, comprising two variable drives each per rotor blade, a bearing element acting between the rotor blade and rotor hub which has a freely rotatable bearing ring, wherein the method has the following process steps: setting the bearing ring into a permanent rotation by a first drive, and adjusting the setting angle of the rotor blade by a second drive.
