Advantages of Using DFS EncodersVersus Conventional Encoders

Conventional Encoders The DFS Solution

Limited PulsesPer Revolution

Many industrial applications require a higher linecount than has been available with traditionalincremental encoders. In the past, there wereseveral ways to increase resolution: quadrature,interpolation, or using a larger encoder.

The DFS has a completely new ASIC design,which provides 1 to 65,536 pulses perrevolution, and up to 262,144 counts afterquadrature; significantly increasing resolutionavailable in incremental encoders.

Shock, Vibration& TemperatureLimitations

The rotating discs used in encoders are typicallyglass or plastic. Glass discs can shatter whenexposed to excessive vibration or shock. Plasticdiscs, while they won’t shatter, cannot achieve thesame level of accuracy as glass discs. Additionally,they are limited to a lower working temperature,

rendering them unsuitable for the temperaturetolerances often required in harsh environments.

The DFS encoder features a nickel code discdesigned both for increased robustness and ahigher temperature tolerance (-20…+100°C).

Bearing Lifetimeand Run Out

The life of an encoder bearing can be shortenedby several factors: high shaft loads, high speeds ofrotation, and shaft misalignment. Once a bearingfails, the encoder needs to be replaced.

The loads on the bearings have been greatlyreduced on the DFS due to the 30 mmdistance between the bearings. This greaterbearing distance also decreases vibrationof the encoder, which helps extend the lifeof the bearings.

Programmability Typical encoders are shipped by the manufacturerwith the customers’ desired line count, pulse andelectrical interface preset and unchangeable. Thismeans that if customers need several encoders

with various line counts and/or electricalinterfaces, they will need to have several encodersfor backup in inventory.

The programmable versions of the DFS allow theuser to program the encoder to the line countdesired and reprogram it, as needed.

Additionally, zero set and electrical interface (toeither TTL or HTL) can be programmed, which isvery unique to SICK|STEGMANN DFS encoders.

A simple programming tool connected to a PCwith a USB cable is used for all programmingfunctions.

Axial and RadialCable Outlets

Currently, when users require cable outlets fortheir encoders, they have the choice of a radial oraxial outlet. It is possible they will need encoderswith both in the same environment requiringadditional inventory. Also, if the cable is somehowdamaged, the encoder has to be returned tothe manufacturer who will repair the encoder byreplacing the cable.

The DFS encoders are available with a pluggableoutlet that can be used in either a radial or axialdirection which requires less installation depth.Since it is detachable, if the cable is damaged,no repair is necessary by the manufacturer.The customer can simply order a new cableand plug it into the encoder. Various cablelengths and connectors at the end of the cableare also available.

RotatingEncoder Disk

Absolute rotaryencoder withconventional codedisk.

Conventional Optical Absolute Encoder DisksA conventional absolute encoder disk features a series ofconcentric tracks, each consisting of a pattern of transparentand opaque segments. These independent tracks provide aunique combination of absolute values for each resolvableposition. One track is needed for each “bit” of position infor-mation that is output as either a serial or parallel data “word.” The preferred code format is Gray Code, in which only one bit ofinformation changes between adjacent positions on the disk.This limits the position error from the track sensors to plus or

minus one count. Other available codes, such as Natural Binaryor Binary Coded Decimal (BCD), may have several bits changebetween adjacent positions.

Magnetic Absolute EncodersMany applications requireresistance to extremely highshock and vibration, widetemperature variations,or high humidity withcondensation. Our magneticabsolute encoders meetthese unique challenges.

Magnetic field strengthof a proprietary 32-polemagnetic ring is measuredusing two strategicallyspaced magneto-resistorsthat pick up variation of themagnetic field intensity alongthe circumference of thering. The resulting 32 sine/cosine signals per turn (5-bit)are then enhanced by 8-bitinterpolation. A single north-south pole magnet, read bya Hall effect sensor, is usedto assign absolute values toindividual sine/cosine cycles.Thus, the 32-pole magnetic

Use absolute encoders when position datamust be retained after loss of power.

Basic Operation of Optical Rotary Absolute EncodersAs with incremental encoders, absolute optical rotary encodersuse a rotating disk to interrupt the light path to a photodetector,which produces an output signal. However, absolute encodersread uniquely coded tracks to generate position information. Notwo adjacent positions are alike. Therefore, absolute encodersdo not lose position data when power is lost. True position isavailable as soon as power is restored. Application examplesinclude robotics, lead/ball screws, overhead cranes, and rackan pinion applications.

ring is calibrated for a 13-bitsingle-turn absolute positionfeedback. Additional softwareis used to compensate fortemperature variation andresulting differential thermalexpansion to insure dataintegrity.

Electronic Zero Position TeachWith all our absoluteencoders, the zero position iselectronically assigned by theuser to the current mechanicalposition by activation of apushbutton or set line. Nomechanical detachment orrotation of the encoder isnecessary.

Absolute EncodersSingle and Multi-Turn




Serial TransmissionWe developed SSI(Synchronous Serial Interface)to offer a cost-effectivesolution for long cable runs.The encoder produces serialdata which is transmittedusing only six wires, regardlessof encoder resolution. This isideal for transmission at highspeed over long distances— up to 3000 feet. Superiornoise immunity is achievedusing differential clock anddata signals.

Single- and Multi-TurnAbsolute EncodersUse single-turn encoderswhen the full range ofmotion in the applicationoccurs within one fullrevolution (360°) of theencoder shaft. Multi-turnencoders are recommendedfor applications involvingmultiple revolutions of theencoder shaft.

In our multi-turn encoders, ahigh precision, miniaturizedgear train, with a magneton each gear stage, isused to mechanically storeposition information over asmany as 8,192 turns. Theposition of each gear stageis determined with a pair ofHall sensors. This eliminatesthe need for costly and oftenunreliable counters andbattery back up systems.Also, position changes thatoccur while the power is offare automatically tracked.

Serial to Parallel ConversionModuleThe AD-SSI-PA convertermodule can be used withour SSI absolute encoders toconvert the transmitted datafrom serial to parallel format.These devices can be used ifthe control does not directlyaccept the SSI format.

Fieldbus SystemsOur absolute encoders canalso be supplied with popularfieldbus interfaces includingDeviceNet, Profibus, andCANopen.

L 230 Magnetic (Lincoder ®)The Lincoder system consists of a magnetic tape and sensorhead. The magnetic tape provides the scale for measuringsystems up to 40 meters long. The absolute information ismagnetized onto the tape in a 12-bit sequential code. Thisposition information is enhanced by interpolation of sine/cosine signals provided by an additional incremental track thatis magnetized on the tape. The magnetic tape is laminated ontoa ferromagnetic steel strip, which is used both as a magnetic

return path and a dimensionally stable mounting aid. Themagnetic tape is supplied with an adhesive back for mountingby the user.

A non-contact magnetic sensor with integrated electronics ismounted to the apparatus whose position is to be measured.As the sensor moves over the measuring tape, its position isoutput with a resolution as low as 1 µm over a 16 meter range,or 10 µm over a 40 meter range. Position data is output viareal-time compensated SSI (Synchronous Serial Interface),HIPERFACE, or RS 485. The Lincoder is also programmable viaRS 485, and a number of parameters such as offset, resolutionand start points can be configured by the user.

Linear Encoders and Wire-Draw SystemsUse linear encoders to measure incremental or absolute position along any axis.Linear encoders can be used in applications up to 1.7 kilometers long.

KH 53 (Pomux ®) and Advanced KH 53Long Distance Linear EncodersThis style of encoder is unique to SICK | STEGMANN and allowsabsolute measurement of up to 1.7 kilometers! The KH 53consists of two basic components: Omega Profile sectionsand the sensor head. Each Omega Profile section containsa number of powerful permanent magnets. The separationbetween each magnet is unique and never repeated. Theseunique separations build up a code over the complete

measurement path. In a working system, several OmegaProfile sections are placed end to end along the completemeasurement path. The total length of the system determinesthe number of profiles required. Each profile section is labeledwith an identification number indicating the order in which thesections should be mounted.

The sensor head moves over the Omega Profile sectionswithout contact, and produces absolute positional data. TheKH 53 allows a generous vertical tolerance of ±10 mm arounda 25 mm nominal value, and a horizontal tolerance of ±10mm around the centerline. The output is available in SSI, andProfibus. Other networks can be realized using commerciallyavailable I/O modules.

In addition, this modular system offers several benefits tothe user. If the measurement length of the system needs toincrease in the future, the user simply needs to mount the extraprofiles required. If the Omega Profile becomes damaged, onlythe damaged sections need to be replaced.

The Advanced KH 53 has 54 m or 548 m measuring lengths,a positional/mounting tolerance to ±20 mm, and an operatingtemperature of -30 to 70°C. The Advanced KH 53 has theadded advantage of requiring less installation time than thestandard KH 53.

Length Measuring Systems




BTF/PRF Wire-Draw EncodersWire-draw encoders are linear-to-rotational, industrial motionconversion modules, coupled with encoder feedback, to providecost-effective linear position measurement solutions thatprecisely fit your requirements. These systems are housed inrugged industrial enclosures, and contain a stainless steel orthermoplastic composite cable wound on a precise, constant-diameter spool. The cable is attached to the apparatus whoseposition is being measured, and is extended and retracted

as the apparatus moves. A spring on the spool maintainscable tension. Position feedback is provided by a standardincremental or absolute rotary shaft encoder.

These position transducers allow very flexible measuring paths,since the cable can be guided around obstacles using pulleys,etc. The heavy-duty enclosure of the encoder and spool housingprovide excellent protection against contaminants, shock andother abuses.

BKS/PKS Wire-Draw EncodersIn these compact wire-draw encoders, the encoder is integratedinto the wire-draw mechanism to minimize the size of the unit.

The number of drum rotations, which is proportional tothe length being measured, is counted by an encoder andconverted to a standard encoder output signal. This provideshigh-resolution position or distance information for linearmeasurement paths, even under difficult mounting conditions.

Precise linear guidance, as required for other lengthmeasurement systems, is not necessary.

The choice between absolute and incremental wire-drawencoders enables made-to-measure solutions for manyapplications: SSI interface for absolute wire-draw encoders,TTL interface for incremental wire-draw encoders. Bothinterfaces are common in automation technology and meet itsexacting requirements.

The measuring lengths up to 5 m cover most of the possibleapplications, for example in:

Presses, punching and injection machines, storage technology,wood and sheet metal processing machines, constructionmachinery, medical technology and many other industries.

HIPERDRIVE (Highly Integrated Performance Drive) is an integrated drive system with absolute positioning, suitable for all kindsof format adjustment in machines and installations. The operations system includes a motor, gears, absolute encoder andfield bus communication capability.

Modern logistic concepts call for smaller batch sizes in many production areas, with numerous adjustments being performedduring product changeovers. The HIPERDRIVES ensure efficient, cost-effective and high-precision automation of adjustmentsto auxiliary axes. This process is normally called “format adjustment,” but in some markets, “automatic size change” is morefamiliar.

The HDA family, with a maximum torque rating of 20 Nm, and the HRA family, with a torque rating of 1 Nm to 12 Nm, are theresults of a consistent and complete integration of power transmission, brushless DC motor, absolute encoder and power

electronics into one positioning drive.

Motor Feedback Systems

Today’s high-performance digital servo drive systems requireabsolute feedback for position control and high-resolutionincremental feedback for speed control. Both are available.

Our SinCos family of servo motor feedback devices combinescommunication, speed regulation, and position information ina single device.

Encoder Accessories

The HIPERFACE interface adapter modules allow users to connect single-turn or multi-turn encoders that have the HIPERFACE interfaceto systems using other communication protocols, opening up a variety of application options in all areas of automation technology.

Motor Feedback Meets Factory Automation

In conjunction with a HIPERFACE interface adapter module, encoders can be usedin a broad range of applications in automation technology. For example where:

• High encoder resolutions are necessary — up to 262,000 counts per turn can be generated easily in the interface adapter via interpolation of the HIPERFACEencoder signals.

• Space is very limited.• Environmental conditions such as dirt, temperature, shock and/or vibration

must be isolated from the electronics.

• Customer-specific encoder flange and housing options are required, which must be realized quickly and at a low cost.

At the output of the interface adapter modules, SSI, Profibus, DeviceNet andCANopen are available, using standard M12 connectors. These interfaces fulfillthe high requirements of automation technology. Further, the diverse range ofpossible combinations of interface adapter modules and encoders provides ahigh level of flexibility, coupled with low part replacement and stocking costs.
