Exposed linear encoders

Linear encoders measure the positionof linear axes without mechanicalintermediaries, thereby eliminating
multiple potential sources of error:• Positioning error due to thermal changes
in the recirculating ball screw• Reversal error• Kinematic error due to the ball-screw
pitch error
Linear encoders are therefore essential
components on machines requiring highpositioning accuracy and feed rates.

Exposed linear encoders are used onmachines that require high-accuracy
measurement feedback. Typicalapplications include the following:• Production and measurement equipmentin the semiconductor industry• PCB assembly machines• Ultra-precision equipment such as
diamond lathes for optical components,
facing lathes for magnetic storage disks
and grinding machines for ferrite parts• High-accuracy machine tools• Measuring machines, comparators,
measuring microscopes and otherprecision measuring devices• Direct-drive motors

Mechanical design
Exposed linear encoders consist of ascale or scale tape read by a non-contact
scanning head.
Because the scale of an exposed linear
encoder is fastened to a mounting surface,achieving high linear encoder accuracy
requires a mounting surface with highevenness.

Incremental encoders

Very high accuracy
The LIP exposed linear encoders arecharacterized by their very small measuring
steps combined with extremely highaccuracy and repeatability. They utilize
the interferential scanning principle andfeature an OPTODUR phase grating as
their measuring standard. The LIP 211
and LIP 291 linear encoders output theirposition information as a position value.
For this to occur, the sinusoidal scanningsignals are highly interpolated in thescanning head and converted into a
position value by the integrated counterfunction. As with all incremental encoders,an absolute reference point is establishedby means of reference marks.
High accuracy
The LIF exposed linear encoders utilize
the interferential scanning principle andpossess a measuring standard made with
the SUPRADUR process. They feature highaccuracy and repeatability, are particularly
easy to install and are equipped with limit
switches and homing tracks. A special
variant, the LIF 481 V, can be used in highvacuums (see separate Product Information
document).
High traversing speeds
The LIDA exposed linear encoders aredesigned for high traversing speeds of up
to 10 m/s. Their various mounting options
allow for particularly flexible deployment.
Depending on the encoder version, steel
scale tapes, glass, or glass ceramic areused as carriers for the METALLUR
gratings. They also feature limit switches.

Measuring principles
Measuring standard

HEIDENHAIN encoders with opticalscanning incorporate measuring standards
consisting of periodic structures known as
graduations.
These graduations are applied to a carrier
substrate made of glass or steel. For
encoders with long measuring lengths,
steel tape is used as the scale substrate.
HEIDENHAIN manufactures the precision
graduations in the following speciallydeveloped, photolithographic processes:• METALLUR: contamination-tolerant
graduation consisting of metal lines ongold; typical grating period: 20 μm• SUPRADUR phase grating: opticallythree-dimensional, planar structure;
particularly tolerant to contamination;
typical grating period: 8 μm and finer• OPTODUR phase grating: optically threedimensional, planar structure withparticularly high reflectance; typicalgrating period: 2 μm and finer• TITANID phase grating: exceptionallyrobust, optically three-dimensional
structure with a high degree ofreflectance; typical grating period: 8 µm

Absolute measuring method

Incremental measuring method

In the absolute measuring method, theposition value is available immediately
upon encoder switch-on and can berequested by the downstream electronics
at any time. There is therefore no need tosearch for the reference position by jogging
the axes. The absolute position informationis read from the graduation on themeasuring standard, which is designed
as a serial absolute code structure. A
separate incremental track is interpolated
for the position value and, depending on
the interface version, is also used togenerate an optional incremental signal.

With the incremental measuring method,
the graduation consists of a periodic grating
structure. Position information is obtained
through the counting of individual
increments (measuring steps) startingfrom a freely settable point of origin. Sincean absolute reference is required toascertain positions, the measuring
standard is provided with an additional
track that bears a reference mark. The
absolute position on the scale, which isestablished by the reference mark, isassigned to exactly one signal period.
Thus, before absolute referencing can beestablished or the most recently selectedreference point can be refound, thisreference mark must first be crossed.

In the most unfavorable case, machine
movements over sizeable sections of themeasuring range may be necessary. To
speed up and simplify such “reference
runs,” many HEIDENHAIN encoders
feature distance-coded referencemarks—multiple reference marks thatare individually spaced in accordance witha mathematical algorithm. The downstream
electronics find the absolute reference point
after traversing two successive referencemarks—thus after only a few millimeters oftraversing distance (see table below).
Encoders with distance-coded referencemarks are identified with a “C” following
the model designation (e.g., LIF 181 C).
With distance-coded reference marks, theabsolute reference point R is calculated
by counting the increments between two
reference marks and by applying thefollowing formula:
P1 = (abs R–sgn R–1) x N + (sgn R–sgn D) x abs MRR
2
2
where:
R = 2 x MRR–N

Along with the very fine grating periods,
these processes permit high edge
resolution and excellent homogeneity of
the graduation. In combination with thephotoelectric scanning method, thesecharacteristics are critical for attaining
high-quality output signals.

9Photoelectric scanning

Most HEIDENHAIN encoders utilize thephotoelectric scanning principle. Because
photoelectric scanning is a non-contact
process, it does not induce wear. Thismethod detects even extremely finegraduation lines down to a width of only
a few micrometers and generates output
signals with very small signal periods.
The finer the grating period of a measuring
standard, the greater the effect of diffraction
on photoelectric scanning. HEIDENHAIN
linear encoders employ two scanningprinciples:• The imaging scanning principle forgrating periods ranging from 10 μm to200 μm• The interferential scanning principle
for very fine grating periods of 4 µm
and smaller

Imaging scanning principle
Put simply, the imaging scanning principle
uses projected-light signal generation bywhich two gratings with equal or similar
grating periods (the scale and the scanning
reticle) are moved relative to each other.
The carrier material of the scanning reticle
is transparent, whereas the graduation of
the measuring standard may be applied toa transparent material or to a reflective
material.

Signal period
360° elec.

When parallel light passes through a
grating structure, light and dark fields areprojected at a certain distance where there
is an index grating with the same or similar
grating period. When the two gratings
move relative to each other, the incident
light is modulated: If the gaps are aligned,then light passes through. If the lines cover
the gaps, then no light passes through.
This fluctuating light is converted into
electrical signals by photocells. The
specially structured grating of the scanning
reticle filters the light so as to generatenearly sinusoidal output signals. The
smaller the graduation period of the grating
structure, the closer and more tightly
toleranced the gap must be between thescanning reticle and the scale. In encoders
that use the imaging scanning principle,
workable mounting tolerances are
attainable starting at a minimum grating
period of 10 μm.

The sensor generates four nearlysinusoidal current signals (I0°, I90°, I180°,
and I270°), phase-shifted relative to eachother by 90° elec. These scanningsignals do not initially exhibit symmetry
about the zero line. For this reason, thephotocells are connected in anti-parallel,
thereby producing two 90° elec. phaseshifted output signals, I1 and I2, which
are symmetrical about the zero line.
In the xy-representation on an
oscilloscope, the signals form a
Lissajous figure. Ideal output signals
appear as a centered circle. Deviations
in circularity and position are caused byposition errors and therefore go directly
into the measurement result. The sizeof the circle, which corresponds to theamplitude of the output signal, can vary
within certain limits without influencing
the measuring accuracy.

The LIC and LIDA linear encoders use theimaging scanning principle.

90°
elec.

Interferential scanning principle
The interferential scanning principle
exploits the diffraction and interference oflight on finely divided gratings in order toproduce the signals used to measuredisplacement.
A step grating is used as the measuring
standard: reflective lines with a height of
0.2 µm are applied to a flat, reflective
surface. In front of this is the scanning
reticle—a transparent phase grating withthe same grating period as the scale.
When a light wave passes through thescanning reticle, it is diffracted into threepartial waves of the orders +1, 0 and –1,
with nearly equal luminous intensity. The
waves are diffracted by the scale such thatmost of the luminous intensity is found in
the reflected diffraction orders +1 and –1.
These partial waves meet again at thephase grating of the scanning reticle,
where they are diffracted again andinterfere. This produces essentially threewaves that leave the scanning reticle atdifferent angles. Photocells convert thesealternating light intensities into electricalsignals.

When there is relative motion between thescale and the scanning reticle, thediffracted wavefronts undergo a phaseshift: movement by the amount of one
grating period shifts the positive first-orderdiffraction wavefront by one wavelength in
the positive direction, while the negative
first-order diffraction wavefront is displacedby one wavelength in the negative
direction. Since the two waves interferewith each other upon exiting the phasegrating, these waves are shifted relative toeach other by two wavelengths. This
results in two signal periods when there isrelative motion of just one grating period.
Interferential encoders use grating periodsof, for example, 8 µm, 4 µm, or finer. Theirscanning signals are largely free of
harmonics and can be highly interpolated.
These encoders are therefore especiallywell-suited for small measuring steps andhigh accuracy. They nevertheless feature
workable mounting tolerances.
The LIP, LIF and PP linear encoders use theinterferential scanning principle.

11Reliability

Low sensitivity to contamination
Both the high quality of the grating and thescanning method are responsible for theaccuracy and reliability of linear encoders.
Exposed linear encoders from HEIDENHAIN
employ single-field scanning in which asingle large scanning field is used togenerate the scanning signals. Local
contamination on the measuring standard(e.g., fingerprints from the mounting
process or oil residues from guideways)
has only a slight influence on the lightintensity of the signal components andthus on the scanning signals. Although thiscontamination does cause a change in theamplitude of the output signals, their offset
and phase position remain unaffected. The
signals remain highly interpolable, and theposition error within one signal period
remains small.

In the OPTODUR and SUPRADUR
processes, a transparent layer is first
applied onto the reflective primary layer.
For creating an optically three-dimensional
phase grating, an extremely thin, hard
chromium layer is applied at a thickness of
only a few nanometers. The graduations forthe imaging scanning principle exhibit asimilar design and are manufactured in the
METALLUR process. A reflective gold layer
is covered with a thin layer of glass. On it
are chromium lines acting as absorbers.
Since they are only several nanometers
thick, these lines are semitransparent.
Measuring standards with OPTODUR,SUPRADUR or METALLUR graduations
have proven to be particularly robust andinsensitive to contamination because
the low height of their structure leaves
practically no surface for dust, dirt,
or water particles to accumulate.

The LIDA, LIF, and LIP 6000 encoders
are equipped with the HSP 1.0 signal
processor ASIC from HEIDENHAIN. This
ASIC continuously monitors the scanningsignal and nearly fully compensates forfluctuations in signal amplitude. If thesignal amplitude decreases as the result ofcontamination on the scanning reticle ormeasuring standard, the ASIC reacts byincreasing the LED current. The ensuingincrease in LED light intensity barely
raises the noise level, even in the case ofstrong signal stabilization. As a result,contamination has only a very slight effecton interpolation error and position noise.

Depending on the nature of thecontamination, this feature can evenprevent encoder failure. This is particularly
true of the LIDA 400 and LIF 400, whichfeature a very large scanning surface area
(14.5 mm2) relative to their grating period.
The same goes for the LIC 4100, which
has a scanning surface area of 15.5 mm2.
Even in the case of contamination fromprinter’s ink, PCB dust, or drops of water or
oil of up to 3 mm in diameter, theseencoders continue to provide high-quality
signals. The position error remains far
below the values specified for the accuracy
grade of the scale.

Workable mounting tolerances
Very small signal periods usually come withvery narrow mounting tolerances for the
gap between the scanning head and scaletape. This is the result of diffraction causedby the grating structures. Such diffraction
can lead to a signal attenuation of 50 %upon a gap change of only ±0.1 mm. Theinterferential scanning principle andinnovative index gratings on encoders
that use the imaging principle allow for
workable mounting tolerances despite tiny
signal periods.
The mounting tolerances of exposed linear
encoders from HEIDENHAIN have only aslight influence on the output signals. In
particular, the specified distance tolerance
between the scale and scanning head(scanning gap) causes only a negligible
change in the signal amplitude. During
operation, the reliability and stability of thesignals are additionally improved by the
HSP 1.0. The two diagrams illustrate thecorrelation between the scanning gap andsignal amplitude for the encoders of the
LIDA 400 and LIF 400 series.

Measuring accuracy

Encoder-specific position error includes:• The accuracy of the measuring standard• The accuracy of interpolation• Position noise
Accuracy of the measuring standard
The accuracy of the measuring standard ismainly determined by:• The homogeneity and period resolutionof the graduation• The alignment of the graduation on its
carrier• The stability of the graduation carrier
The accuracy of the measuring standard isindicated by the uncompensated maximum
value of the baseline error. This accuracy
is ascertained under ideal conditions via
measurement of the position error with aserially produced scanning head. The
distance between the measuring points is
equivalent to the integer multiple of thesignal period. As a result, interpolation
errors have no effect.
The accuracy grade a defines the upper
limit of the baseline error within any
section up to one meter in length. For
certain special encoders, an additional
baseline error is stated for defined intervalsof the measuring standard.

The accuracy of interpolation is ascertainedwith a serially produced measuring
standard and is indicated by a typicalmaximum value u of the interpolation error.
Encoders with an analog interface aretested with a HEIDENHAIN electronic
device (e.g., EIB 741). The maximum values
do not include position noise and are
indicated in the specifications.

Position noise
Position noise is a random process leading
to unpredictable position errors. The position
values are grouped around an expectedvalue in the form of a frequency
distribution.
The amount of position noise depends
on the signal processing bandwidths
necessary for forming the position values.
It is ascertained within a defined timeinterval and is stated as a product-specific
RMS value.
In the speed control loop, position noise
influences the speed stability at low
traversing speeds.

be measured and considered individuallyin order to evaluate the overall accuracy.
Deformation of the graduation
Errors due to a deformation of thegraduation are not to be neglected. Suchdeformation occurs when the measuring
standard is mounted on an uneven surface(e.g., a convex surface).

Vibration
To function properly, linear encoders mustnot be continuously subjected to strong
vibration. The best mounting surfaces are
therefore solid and stable machineelements. Encoders should not bemounted on hollow parts or with adapter
blocks, etc.
Influence of temperature
In order to avoid temperature effects, thelinear encoders should not be mounted inclose proximity to heat sources.

Mounting location
Poor mounting of linear encoders canaggravate the effect of guideway error on
measuring accuracy. To keep the resulting
Abbé error as small as possible, the scale
should ideally be mounted to the machineslide and at the height of the table. It is
important to ensure that the mounting
surface is parallel to the machine guideway.

The interpolation error begins having aneffect even at very low traversing speeds
and during repeated measurements.
Fluctuations in the traversing speed are a
result, particularly within the speed control
loop.

Linear scales

Calibration chart

Exposed linear encoders are made up of
two separate components: the scanninghead and linear scale or scale tape, which
are brought together solely over themachine guideway. For this reason, themachine must be designed from the very
beginning to meet the following
requirements:• The machine guideway must be
designed such that the scanning gap
tolerances are complied with at thelocation where the encoder is installed(see Specifications)• The mounting surface of the scale mustmeet the flatness requirements• To facilitate adjustment of the scanninghead to the scale, the scanning headshould be fastened with a mounting
bracketAll HEIDENHAIN linear encoders areinspected for accuracy and proper
functioning prior to shipping.
The accuracy of the linear encoders is
ascertained during traversing movements
in both directions. The number of measuring
positions is selected such that not only thelong-range errors but also the position errors
within a single signal period are very
accurately determined.
A Quality Inspection Document confirms
the stated graduation accuracy of each
encoder. The listed calibration standards
ensure traceability to recognized national
or international standards, such as required
by EN ISO 9001.

LIC 41x5
LIDA 4x5
Linear encoders of the LIC 41x5 and
LIDA 4x5 series are specially designed forlong measuring lengths. They are mountedwith scale carrier sections screwed onto
the mounting surface or adhesively bondedwith PRECIMET adhesive mounting film.
The single-piece steel scale tape is thenpulled through the carrier sections,
tensioned as specified, and secured atits ends to the machine base. The
LIC 41x5 and LIDA 4x5 encoders thereby
exhibit the same thermal behavior as thatof the mounting surface.

The encoders of these series are also
designed for long measuring lengths. The
scale carrier sections are adhesively
bonded to the mounting surface withPRECIMET adhesive mounting film; thesingle-piece scale tape is pulled through,and the midpoint is secured to themachine base. This mounting method
allows the scale tape to expand freely atboth ends and ensures a defined thermal
behavior.

Because exposed linear encoders areassembled on the machine, they must be
precisely adjusted after mounting. Thisadjustment determines the final accuracyof the encoder. It is therefore advisable
to design the machine such that thisadjustment is as easy as possible, while
also ensuring the greatest possible degreeof mounting stability.

The signals from the LIC, LIP 6000, and
LIP 200 can be readily adjusted with thePWM 20/21 adjustment and testing
package. For all other exposed linear
encoders, the incremental and referencemark signals are adjusted through a slightrotation of the scanning head (for the

General mechanical information

Signal-quality indicator

The LIDA, LIF, and LIP 6071 linear encoders
feature an integrated signal-quality indicatorwith a multicolor LED, permitting fast andeasy signal-quality checks during operation.
This feature provides a number of benefits:• Scanning-signal quality visualization
through a multicolor LED• Continuous monitoring of incremental
signals over the entire measuring length• Indication of reference-mark signal
behavior• Quick signal-quality checks in the field
without additional aids
The built-in signal-quality indicator permits
both a reliable assessment of theincremental signals and inspection of thereference mark signal. The quality of theincremental signals is indicated by arange of colors, permitting quite detailed
signal-quality differentiation. The tolerance
conformity of the reference mark signal isshown by means of a pass/fail indicator.

The scanning heads of exposed linear
encoders feature the following degrees
of protection:

Thermal characteristics
The thermal behavior of the linear encoder
is an essential criterion for the working
accuracy of the machine. As a general rule,the thermal behavior of the linear encoder
should match that of the workpiece ormeasured object. During temperaturechanges, the linear encoder should expand
or contract in a defined, reproduciblemanner.
The graduation carriers of HEIDENHAIN
linear encoders (see Specifications) havediffering coefficients of thermal expansion.
This makes it possible to select the linear
encoder with the thermal behavior best
suited to the application.

Temperature range
The operating temperature range states
the limits of ambient temperature within
which the specifications of the linear
encoder are complied with.
The storage temperature range of –20 °C
to +70 °C applies when the unit remains in
its packaging.

Parts subject to wear
Encoders from HEIDENHAIN are
designed for a long service life. Preventive
maintenance is not required. However, they
do contain components that are subject towear, depending on the application andhow they are deployed. This especiallyapplies to cables that are subjected tofrequent flexing.
Other parts subject to wear are thebearings in encoders with integral bearing,
the radial shaft seal rings in rotary encoders
and angle encoders, and the sealing lips onsealed linear encoders.

System tests
Encoders from HEIDENHAIN are usually
integrated as components into complete
systems. Applications of this type require
full-system, extensive testing,regardless of the encoder’sspecifications.
The specifications provided in thisbrochure apply only to the encoder andnot to the entire system. Any operationof the encoder outside of the specified
range or outside of its proper andintended use is at the user’s own risk.
In safety-related systems, the encoder’sposition value must be tested by thehigher-level system after switch-on.

The scales have no special protection. If
the scales are exposed to contamination,
protective measures must be taken.
Acceleration
Linear encoders are subject to various
types of acceleration during operationand mounting.
• The indicated maximum values forvibration apply to frequencies of 55 Hz
to 2000 Hz (EN 60068-2-6). If, dependingon the application and the mounting
scenario, the permissible acceleration
values are exceeded (e.g., in the case ofresonances), then the encoder canbecome damaged. Extensive testing of
the entire system is therefore required• The maximum permissible acceleration
values (semi-sinusoidal shock) for shock
and impact loads are valid for 11 ms or
6 ms (EN 60068-2-27). Under nocircumstances should a hammer orsimilar implement be used to adjust or
position the encoder

Mounting
The steps and dimensions that must
be complied with during mounting
are specified solely in the mounting
instructions supplied with the device.
All mounting-related information in thisbrochure is therefore provisional andnon-binding, and will not become thesubject matter of a contract.

LED indicator for reference-mark-signal(operating check)
When the reference mark is traversed,
the LED briefly lights up in red or blue: Out of tolerance Within tolerance
LED indicator for control margin
A flashing LED that turns dark every
2.5 seconds indicates that the control
margin of the scanning ASIC is almost
exhausted. In this case you should clean
the measuring standard and the scanningwindow of the scanning head in compliancewith the relevant information in themounting instructions. The encoder may
also need to be checked for correct
mounting.

Functional safety

With the absolute linear encoders of the
LIC 4100 series, HEIDENHAIN offers an
ideal solution for position acquisition on
linear axes in safety-related applications.
In conjunction with a safe control, theencoders can be used as single-encoder
systems in applications with control
category SIL 2 (as per EN 61508) or
performance level “d” (as per
EN ISO 13849).

Fault exclusion for the loosening of themechanical connection
The machine manufacturer is responsible
for the dimensioning of mechanicalconnections in a drive system. During themechanical design phase, the OEM will
ideally consider the conditions within theapplication. Verifying a safe connection,
however, is both cost- and time-intensive.
That’s why HEIDENHAIN has developed a
type-examined mechanical fault exclusion
for the LIC 4100 series.

The reliable transmission of the position isbased on two independently generated
absolute position values and on error bits
provided to the safe control. The functionsof the encoder can be used for numerous
safety functions of the complete system
as per EN 61800-5-2.
The LIC 4100 linear encoder can provide asafe, absolute position value at any time—
including immediately after switch-on.
Purely serial data transfer is performed via
the bidirectional EnDat 2.2 interface.

In addition to the data interface, themechanical connection of the encoder tothe drive is also safety-relevant. In table D8of the standard for electrical drive systems(EN 61800-5-2), the loosening of themechanical connection between theencoder and the motor is listed as afault that requires consideration. Since
it cannot be guaranteed that the control
will detect such errors, fault exclusion
for the loosening of the mechanicalconnection is required in many cases.
Unless otherwise specified, HEIDENHAIN
encoders are designed for a service life of
20 years (in accordance with ISO 13849).

Mounting temperature
All information on screw connections
is based on a mounting temperatureof 15 °C to 35 °C.
Measuring length
During temperature changes, different
coefficients of thermal expansion result
due to the different materials of the scaletape and the mounting surface. The
localized shift resulting from different
coefficients of thermal expansion between
the scale tape and the mounting surface(shearing of the adhesive film) must notexceed a value of 0.75 mm. It is from thisthat the stated measuring lengths arise.
Longer measuring lengths are possible inindividual cases. This must be checked forthe given customer application.

Interfaces» 1 VPP incremental signals

HEIDENHAIN encoders with the » 1 VPP
interface provide voltage signals that arehighly interpolatable.

Limit switches

LIDA 400 encoders are equipped with two
limit switches that enable limit-position
detection and the formation of homing
tracks. The limit switches are activatedby differing adhesive magnets, thereby
permitting precise switching of the rightor left limit switches. The magnets canbe configured in series for the creation of
homing tracks. The signals from the limit
switches L1 and L2 are transmitted overseparate lines and are therefore directly
available. Nevertheless, the cable has only
a very thin diameter of 3.7 mm in order tokeep the forces on movable machineelements to a minimum.

Signal period
360° elec.

The sinusoidal incremental signals A and
B are phase-shifted by 90° elec. and have atypical amplitude of 1 VPP. The illustrated
sequence of output signals, with B lagging
A, applies to the direction of motion shownin the dimension drawing.
The reference mark signal R has a uniqueassignment to the incremental signals. The
output signal may be lower next to thereference mark.

Further information:
For detailed descriptions of all available
interfaces, as well as general electricalinformation, refer to the Interfaces of
HEIDENHAIN Encoders brochure.

The incremental signals conform with the
1 VPP or TTL interface.

The incremental signals are output as thesquare-wave pulse trains Ua1 and Ua2 witha 90° elec. phase shift. The reference marksignal consists of one or more reference
pulses Ua0, which are gated with theincremental signals. In addition, theintegrated electronics generate theinverted signals ¢, £, and ¤ fornoise-immune transmission. The illustrated
sequence of output signals—with Ua2
lagging Ua1—applies to the direction of
motion shown in the dimension drawing.

4-fold evaluation

The inverted signals ¢, £, ¤ are not shown

The fault detection signal ¥ indicatesfault conditions such as an interruption in the
supply lines, failure of the light source, etc.
The distance between two successive
edges of the incremental signals Ua1 andUa2 through 1-fold, 2-fold, or 4-foldevaluation is one measuring step.

Besides the incremental graduation, theLIF 4x1 and LIP 60x1 encoders feature ahoming track and limit switches for limit
position detection.
The signals for position detection H and
L are transmitted at the TTL level over the
separate lines H and L and are therefore
directly available. Yet the cable has only avery thin diameter of 4.5 mm (LIF 4x1) or
3.7 mm (LIP 60x1) in order to keep theforces on movable machine elements to aminimum.

The incremental signals conform with the
1 VPP or TTL interface.

Versions of the EnDat interface

EnDat interface

The EnDat interface is a digital bidirectional
interface for encoders. It is capable ofoutputting position values, reading andupdating information stored in the encoder,and storing new information in the encoder.
Thanks to the serial transmission method,
only four signal lines are required. The data
(DATA) are transmitted synchronously with
the CLOCK signal from the downstream
electronics. The type of transmission(position values, parameters, diagnostics,etc.) is selected via mode commands thatthe downstream electronics send to theencoder. Some functions are available onlywith EnDat 2.2 mode commands.

HEIDENHAIN encoders provide all of theinformation needed for setup, monitoringand diagnostics. The type of information
available depends on whether the encoder
is incremental or absolute and on whichinterface is being used.

Absolute encoders employ serial datatransmission. Depending on the interface,
additional 1 VPP incremental signals canbe output. The signals are extensively
monitored within the encoder. The
monitoring results (particularly valuation
numbers) can be transmitted to thedownstream electronics along with theposition values via the serial interface(digital diagnostics interface). The
following information is available:• Error message: position value is
not reliable• Warning: an internal functional limitof the encoder has been reached• Valuation numbers:– Detailed information about theencoder’s function reserve– Identical scaling for all HEIDENHAIN
encoders– Cyclic reading capability
This enables the downstream electronics toevaluate the current status of the encoderwith little effort, even in closed-loop mode.
For the analysis of these encoders,
HEIDENHAIN offers the appropriate PWM
inspection devices and PWT testing
devices. Based on how these devices areintegrated, a distinction is made between
two types of diagnostics:• Encoder diagnostics: the encoder isconnected directly to the testing or
inspection device, thereby enabling adetailed analysis of encoder functions.
• Monitoring mode: the PWM inspection
device is linked into the closed control
loop (via suitable testing adapters if
needed). This enables real-time diagnosisof the machine or equipment during
operation. The available functions dependon the interface.

Signal converters from HEIDENHAIN adapt
the encoder signals to the interface of thedownstream electronics. They are used
when the downstream electronics areunable to directly process the output
signals of HEIDENHAIN encoders or when
additional interpolation of the signals isnecessary.

Input signals of the signal converters
HEIDENHAIN signal converters canbe connected to encoders with 1 VPP
sinusoidal signals (voltage signals) or
11 µAPP sinusoidal signals (current signals).
Encoders with the EnDat or SSI serialinterface can be connected to various
signal converters as well.
Output signals of the signal converters
The signal converters are available with thefollowing interfaces to the downstream
electronics:• TTL square-wave pulse trains• EnDat 2.2• DRIVE-CLiQ• Fanuc Serial Interface• Mitsubishi high speed interface• Yaskawa Serial Interface• Profibus
Interpolation of the sinusoidal
input signals
In addition to performing signal conversion,
signal converters also interpolate thesinusoidal encoder signals. This permits
finer measuring steps, resulting in higher
control quality and superior positioning
behavior.
