Knowing which way the wind is blowing. Wind power systems must operate at near 100 % availability hence quality and reliability are extremely important. Variable-speed, pitchcontrolled systems are the current state-of-the-art in wind energy system construction. They can be efficiently deployed in the harsh conditions prevalent in both onshore and offshore operations. Build on SICK s competence a competence demonstrated by over ten years experience in this sector and more than 20,000 encoders installed in pitch-controlled systems. Absolute encoder A3M60 built to last. The A3M60 is an extremely robust absolute multiturn encoder in a 60 mm housing. Even under the harshest environmental conditions both onshore and offshore, the multiturn encoder achieves maximum reliability via its magnetic, and thus extremely robust, scanning function. The innovative and gearless multiturn technology reduces the number of moveable parts on the A3M60 to a minimum. This results in a longer service life with reduced maintenance requirements. Absolute encoder AFM60 the wonder of precision. With 30-bit resolution and a high level of robustness, the new absolute multiturn encoder AFM60 sets a new record. Even its little brother the absolute singleturn encoder AFS60 impressive due to its high 18-bit resolution, counts as one of the best products in its 4 industry guide wind power sick 2010-09 subject to change without notice

pitch system rotational speed ControLLEr AZiMutH system market segment. The single resolution, as well as the zero point or offset are programmable. The two new product families are especially suitable for application in the harsh conditions prevalent in wind power systems in other words, when the highest levels of accuracy and availability are called for. Absolute encoder ATM60 the classic design. The absolute multiturn encoders ATM60 are implemented using mechanical drives they deliver the revolution information very reliably and free from interference. The principle of operation is such that a sensor scans permanent magnetic elements arranged on a magnetic scale. This makes high precision possible due to the high base resolution of 8,192 steps per revolution. 2010-09 subject to change without notice industry guide wind power sick 5

Extremely robust and extremely precise. dfs60 the rotary design. The DFS60 is a high-resolution in a 60 mm design. The DFS60 is unique in its class with a maximum number of lines as high as 65,536. Excellent concentricity and exceptional robustness are achieved thanks to the large distance between the ball bearings which support the encoder shaft. The DFS60 is therefore predestined for application in wind power systems. dgs35 the robust design. The s DGS35 are used in the harshest conditions across the globe. The stable design with an enclosure rating of up to IP 66 ensures for a robust but nevertheless high-resolution incremental encoder. Equipped with a through hollow shaft with a maximum diameter of 30 mm, the DGS family is suitable for use in every application. Motor feedback systems sfs60, sfm60 with HipErFACE interface. HIPERFACE motor feedback systems comprise a combination of incremental and absolute encoders, successfully uniting the advantages of both encoder types. They are particularly suited for absolute position finding, with the number of steps being 32,768 per revolution and with a maximum of 4,096 revolutions that gives a total resolution of 134,217,728 steps in the case of the multiturn design. The speed monitoring function is enabled via sine/cosine signals. The storing of motor-specific data in the electronic type label as well as the programming function are further important features of these series. The HIPERFACE interface, which is used in applications across the globe, facilitates the commissioning of these motor feedback systems. p i t c h + A z i m u t h pitch + Azimuth Absolute multiturn encoder A3M60 Absolute singleturn/multiturn encoder AFs/AFM60 A mechanical interface for all relevant electronic encoder interfaces: incremental (DFS60), absolute (AFS/AFM60) and motor feedback systems (SFS/SFM60).
