Functions for GAGE-CHEK 2000 and GAGE-CHEK 4000 SW

Configurable function elements
The functionality of the GAGE-CHEK canbe adapted to the given requirements
through individually configurable function
elements in the Inspector view. Along withfunction elements for the output of
measured values, functions such as apreset table and the storage of minimum
and maximum values are available as well.

Recording minimum andmaximum values (MinMax)
The GAGE-CHEK is equipped with afunction for recording minimum andmaximum values. This function can be
configured for the axes as desired. The
highest and lowest measured values ofa measurement series, including theirdifference, are recorded and can be output
over the data interface. This function isparticularly advantageous for radial run-out
inspection.

Dial gage
The dial gage function lets you make adirect comparison between the acquired
measured values and the nominal value,
warning limits, and tolerance limits. The
measured values are shown as a graph in
the form of a dial gage. For evaluation, the
GAGE-CHEK supports you with a color
depiction of a dial gage.

Configurable data formats for themeasurement output
Along with providing a default format, the
GAGE-CHEK also gives you the option ofstoring your own data formats for datatransmission via RS-232. Thanks to theconfigurability of its data formats, the
GAGE-CHEK is particularly effective as adata logger on retrofitted, manuallyoperated measuring machines. The
measured values are recorded by the
GAGE-CHEK and then relayed to aconnected PC for further processing.

Formula calculations withposition values
The Formula function programmed into
the GAGE-CHEK offers various calculation
operations. For example, the average valueof all axes can be displayed or parallel axes
can be combined.

LOG function for Excel(for GAGE-CHEK 4000 SW)
The GAGE-CHEK 4000 SW software uses
the LOG function to send the measured
values directly to Excel 365 without
requiring any additional software. Excel canthen process the data further, for example
in order to generate measurement series.

ND 287
Evaluation unit for measuring andinspection stations
Thanks to its extensive functionality, theND 287 evaluation unit for one axis is well
suited for measuring and inspection
stations, and can also be used for simple
positioning tasks. The universal encoder
input permits the connection of all
incremental encoders with 11 µAPP and
1 VPP signals, and absolute encoders with
the EnDat 2.2 interface from HEIDENHAIN.

Sorting and tolerance checking
With the sorting and tolerance checking
function of the ND 287, workpieces can beinspected for dimensional accuracy andsorted into classes. The result is shown
through symbols in the color status display,with a corresponding signal applied at theswitching outputs.

DesignThe ND 287 features a sturdy aluminum
die-cast housing. For displaying themeasured values, a graphics-capable
screen shows the status display andsoft keys. Its splash-proof, full-travel
keyboard is designed to handle theshop floor.

Display freeze
For readability, even during rapidly changing
measured values, the display can be frozen
with an external signal. The internal counter
keeps on running.

Functions
The ND 287 provides numerous functions
for the metrological acquisition of individual
values, including functions such as sorting
and tolerance check mode, minimum andmaximum value recording, andmeasurement series storage. Based onthese data, mean values and standard
deviations can be calculated and displayedin histograms or control charts. Thanks to
its modular design, the ND 287 permits theconnection of a second encoder for sum/
difference measurement, or the connectionof an analog sensor (e.g., for temperaturecompensation).
Data interfaces
The ND 287 is equipped with serialinterfaces for the transmission of
measured values to a PC or printer,for the input/output of parameter lists
and compensation value lists, and for
diagnostics:• USB• RS-232-C/V.24• Ethernet 100BaseT (option)
The transmission of measured values canbe initiated on the ND keyboard or via an
external command. With RS-232-C/V.24,
this is done using the software command
CTRL+B or a configurable internal clock.

Mathematical consideration of asecond encoder
A second encoder or a sensor can beconnected to the ND 287 through an
optional encoder module or analog
module input assembly. The data from thetwo encoders can be taken into accountmathematically via operands. The result
and the two measured values are saved.
This opens up further areas of application,such as sum/difference display of two
encoders or temperature compensation bymeans of a temperature sensor.
Recording and evaluating
measurement series
The ND 287 provides a measured-value
memory for the storage of measurement
series. Alternatively, during themeasurement series, the minimum,
maximum, or difference can be displayed.
The displayed value can also be checked
for tolerance conformity with the sorting
function. The saved measured values areevaluated and displayed in the following
ways:• Statistical view (mean value x,
standard deviation s, and range r)• Diagram (graph of the measured values
with minimum, maximum, and meanvalues, as well as tolerance limits)• Measured value overview as a table
Statistical Process Control (SPC)
For SPC, the ND 287 saves up to 1000
measured values in its nonvolatile FIFO
memory. Evaluation is performed with thefollowing functions:• Statistical view of the measured values
in the FIFO memory• Measured value overview as a table• Diagram of the last 30 measured values• Histogram in ten classes with probability
density function and process capability
indexes Cp and Cpk• Control charts for mean value x,
standard deviation s, and range r

EIB 700
Signal converter for computer-aided
measured-value acquisition
For use as evaluation units, the EIB 700
signal converters feature connections forfour encoders. These units are particularly
well suited for the following applications:• Precise position measurement,
especially for inspection stations andmulti-gauging fixtures• Portable, on-site data acquisition(e.g., for machine calibration)• Integration into customized applications(e.g., high-precision measuringmachines)
The EIB 700 series is ideal for applications
requiring high-resolution encoder signals
and rapid measured-value acquisition. Its
Ethernet transmission also enables the useof switches or hubs for connecting morethan one EIB. Wireless LAN transmission,for example, can be used as well.
DesignThe EIB 700 features a bench-top housing.
With a mounting bracket accessory, it canalso be easily installed into a 19-inch
housing. The device is suitable for thefollowing supply voltages:
EIB 741: AC 100 V to 240 V
EIB 742: DC 24 V

Functions
For measured-value generation, theEIB 700 subdivides the signal periods ofthe incremental signals up to 4096-fold.
Automatic adjustment of the sinusoidal
incremental signals reduces the error
within one signal period.
The integrated measured-value memory
enables the EIB 700 series to save typically
250 000 measured values per axis. Basedon the axis, these measured values can besaved by means of either an internal orexternal trigger.
The interval counter permits positiondependent triggering in conjunction withan incremental encoder on Axis 1. For thispurpose, the signals of Axis 1 areinterpolated and forwarded to a position
counter. Triggering pulses are generated
either at a certain position or equidistantly at
configurable intervals. They are continuously
generated once a configurable starting
position is crossed in either counting
direction. The trigger pulses can be used totrigger further internal axes of the EIB or
can also be output over a trigger output.

Data interface
A standard Ethernet interface using TCP/IPor UDP communication is available for data
output, permitting direct connection to aPC, laptop, or industrial PC. The type ofmeasured-value transmission can beselected through the operating mode
(single values, as a block, or upon software
request).
For processing the measured values on aPC, software drivers for Windows, Linux,and LabVIEW are included in delivery, as
are example programs and the EIB
application software. The software driver
makes it easy to program customized
applications, and the example programs
demonstrate the potential of the EIB 700
series. The EIB application software assists
with setting up and demonstrating thecapabilities of the EIB 700 series. This
software is provided as source code andcan serve as a platform for thedevelopment of one’s own applications.

IK 220Signal converter for computer-aided
measured-value acquisition
The IK 220 signal converter is an evaluation
unit for two axes. As a PC counter card, theIK 220 can be inserted directly into a free
PCI slot on the computer.
DesignConnectable to the IK 220 are two
HEIDENHAIN encoders with sinusoidal
current signals (» 11 μAPP), sinusoidal
voltage signals (» 1 VPP), or an
EnDat 2.1 or SSI interface. External latch
inputs/outputs and the output of encoder
signals (» 11 μAPP) can be implemented
by means of additional slot covers(accessory).

Functions
The IK 220 subdivides the signal periodsof the sinusoidal encoder signals up to4096‑fold. The signals are called and stored
through either external latch inputs orsoftware.

IK 220The IK 220 features an integrated
measured value memory. A total of
up to 8192 measured values can be
stored in the buffer memory and canbe output as a single block.
Further processing of the measured
values in the PC is performed by operatorcreated programs. To demonstrate thepossibilities of the PC counter card,
example programs and a software driverare included in delivery.

Analog input (option)
Through an optional input assembly, theND 287 evaluation unit can be equippedwith an additional analog input forconnecting a sensor. The input voltage
range is interpolated 4096-fold; for a sensor
with ±10 V, the resolution is therefore
5 mV. The analog module provides DC 5 V,
DC 12 V, and DC 24 V as supply voltage forthe sensor.

Signal level–0.5 V ≤ UL ≤ 0.9 V with IL ≤ 6 mA
3.9 V ≤ UH ≤ 15.0 V
tmin ≥ 30 ms
Zero reset / set value
Via an external signal, each axis can be set
to the display value zero or to a value
stored in a parameter (SET).
External control of measurement series
Switching the display to MIN, MAX, andDIFF
Continuously applying a LOW signal at thecorresponding switching input activatesthe external operation of measurement
series. The start of a new measurement
series and the switch to the MIN/MAX/
DIFF display are then externally controlled
through further switching inputs.

1)

Also selectable by parameterContact

Pulse

Ignoring reference mark signals(reference pulse lock)
When this input is active, the readout
ignores all of the reference mark signals.
A typical application for this is when linear
measurement is performed with a rotary
encoder and a lead screw.
Activating or deactivating REF mode
After switch-on or a power interruption, thedigital readout can be externally switched
to REF mode. The next signal thendeactivates REF mode (switching function).
Display with axis coupling
The ND 287 can have two optional encoder
inputs. Using switching inputs, you canswitch the display to individual measured
values, a sum, a difference, or any logicaloperation.

EIB 700 and IK 220 signal converters

Switching outputs

The EIB 700 and IK 220 units feature D‑sub
connectors for external operation and theconnection of encoders.

Delay until signal output:tV ≤ 20 ms

With the IK 220, the encoder signals canbe routed out over an additional slot coverand are available as 11 µA current signals
for further processing in evaluationelectronics or EXE pulse-shaping
electronics. A further slot cover contains
the connections for the external inputs/
outputs (e.g., for storing the measured
values).

The ND 287 features open-collector
outputs that switch to 0 V (= Active LOW).

Trigger points (actual value mode)
When the measured value reaches trigger
points defined via parameters, thecorresponding output becomes active.
Up to two trigger points can be defined.
Switch-off ranges( distance-to-go mode)
In distance-to-go mode, the trigger points
function as switch-off ranges, appearing
equidistantly from the display value “0”.

User’s Guide.
Platform for customized applications
The EIB application software is provided assource code, thereby allowing customers
to rapidly implement their own
applications. The application software wasprogrammed using C++/CLI and Windows
Forms in Visual Studio 2008. This
programming environment is widely usedin technical application programming but
does not necessarily provide state-of-theart user interfaces such as those inWindows 10. However, adaptation to othergraphical interfaces can be performed by
the customer.
