Abstract: A braking assembly of a wind turbine includes a slewing ring bearing, at least one first drive mechanism having a first motor and a first drive pinion that rotationally engages the slewing ring bearing. The first motor is pre-tensioned in a first direction by a first amount of force. The braking assembly also includes at least one second drive mechanism having a second motor and a second drive pinion that rotationally engages the slewing ring bearing. The second motor is pre-tensioned in a second direction with a second amount of force. The first direction and the second direction are opposite of each other and the first amount of force are substantially equal to the second amount of force. Thus, the first and second amounts of force substantially cancel each other while also allowing dithering of at least one of the first and second motors, thereby preventing substantial rotational movement of the slewing ring bearing.

The authentication endpoint verifies that the SAML response indicated the user was authenticated by an identity provider. A URL may be retrieved from the relay state data and the user device's web browser is redirected to the URL to provide access to one or more services of the service provider.
