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, pitch-
controlled 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 off-
shore operations.
Build on SICK‘s compe-
tence – 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 multi-
turn encoder achieves
maximum reliability via its
magnetic, and thus extre-
mely robust, scanning func-
tion. The innovative and
gearless multiturn techno-
logy reduces the number
of moveable parts on the
A3M60 to a minimum. This
results in a longer service
life with reduced mainte-
nance 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
55INDUSTRY GUIDE WIND POWER | SICK2010 - 09

market segment. The single
resolution, as well as the
zero point or offset are
programmable.
The two new product fami-
lies 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 imple-
mented using mechanical
drives – they deliver the
revolution information very
reliably and free from inter-
ference. The principle of
operation is such that a
sensor scans permanent
magnetic elements
AZIMUTH SYSTEM
ROTATIONAL SPEED CONTROLLERPITCH SYSTEM
arranged on a magnetic
scale. This makes high
precision possible due to
the high base resolution of
8,192 steps per revolution.

Extremely robust
and extremely precise.
Incremental encoder
DGS35 – the robust design.
The incremental encoders
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.
Incremental encoder
DFS60 – the rotary design.
The DFS60 is a high-reso-
lution incremental encoder
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 pre-
destined for application in
wind power systems.
A mechanical interface for
all relevant electronic
encoder interfaces:
incremental (DFS60),
absolute (AFS/AFM60) and
motor feedback systems
(SFS/SFM60).
Motor feedback systems
SFS60, SFM60 with
HIPERFACE
®
interface.
HIPERFACE
®
motor feed-
back systems comprise a
combination of incremen-
tal and absolute encoders,
successfully uniting the
advantages of both enco-
der types. They are parti-
cularly 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 moni-
toring function is enabled
via sine/cosine signals.
The storing of motor-spe-
cific data in the electronic
type label as well as the
programming function are
further important features
of these series.
The HIPERFACE
®
inter-
face, which is used in
applications across the
globe, facilitates the com-
missioning of these motor
feedback systems.
