Abstract
A rotational positioning system in a wind turbine is provided that comprises a driven part, a plurality of positioning drives coupled to the driven part, a plurality of sensors each arranged to sense a load parameter indicative of the load of the respective positioning drive, and a load controller connected to the plurality of sensors. The load controller is arranged to determine a load of a respective positioning drive based on the sensed load parameter, to compare said load with an expected load value, and to output a signal indicative of a failure of the respective positioning drive in response to the load being smaller than the expected load value.
