DOC 1234.01 E 05/2008

Intelligent Alarm Output allows preventive Maintenance for both Absolute and Incremental Encoders: The ACURO series of Absolute encoders are actively monitoring their operational status. The internal sensor monitors permanently its operational parameters, such as remaining LED life, operating temperature, integrity

Encoders that keep Wind Turbines spinning

Pitch Control direct at the Blade: ! One rev of blade = multiple revs of encoder ! One multiturn absolute encoder per blade ! Recommendation: AC58-MT ! Optimal together with load module ! Also applicable for yaw application

Pitch Control indirect via geared motor: ! One rev of blade = multiple revs of encoder ! One multiturn absolute encoder per motor ! AC58-MT, optional sinewave ! Also used for yawcontrol
