In order to enable a moveable part of an adjusting device of the wind power plant to be held securely on a wind power plant, drive axles are tensioned against each other prior to the holding action, by at least one drive axle being rotated relative to the other drive axles, and by maintaining a tension of the drive axles achieved at the beginning of the holding action by control of the drive axles and by implementing a position control of the drive axles, which controls the drive axles to the respective starting positions of the drive motors of the drive axles at the beginning of the holding action.

Method for retaining a moving part of a wind turbine

In order to be able to better control the movement of the movable part of the wind power plant during an adjustment, the drive axles are tensioned against each other prior to the adjustment by rotating at least one drive axle relative to the other drive axles, and the drive axles are rotated together in the same direction of rotation during the adjustment the drive axles while maintaining the tensioning of the drive axles by way of a position control, until the desired end position of the movable part is reached.
