Functions

REF Reference Mark Evaluation

The ND 287's REF reference mark
evaluation feature automatically
re-establishes the relationship between
axis-slide or measuring-probe positions
and display values that you last defi ned
by setting the datum.

If you do not use the REF feature,
the datums will be lost once the ND is
switched off.

Actual Value/Distance-To-Go

In the Actual Value operating mode, the
ND always displays the current actual
position of the encoder, relative to the
active datum.
In the Distance-To-Go operating mode,
you enter the desired nominal position
and simply traverse to the display value
zero.

The distance-to-go is displayed with
a reversed algebraic sign. For example,
the distance-to-go has a positive sign if
the axis direction from the actual towards
the nominal position is negative.

2. Display Confi guration

Set the display resolution.•

3. Counter Settings

In the Application fi eld, select 1 Axis •
or 2 Axes (only with optional encoder
module or analog module). Two axes
can be coupled through mathematical
functions.
Lock or release the keypad.•
Second decimal point (after 3 decimal •
places).
Reset all parameters to factory default •
settings.

4. Error Compensation

Error Compensation:• Select OFF,

Linear or Non-linear, and enter the
data.

5. Interface Settings

As required.

6. Diagnostics

As required.

Before starting a measurement

Ensure that the distance or angle

actually traversed matches the displayed
value and direction. Deviations may be
due to the following causes:

Signal period•
Counting direction •
Error compensation•
Scale factor•
Application (1 axis or 2 axes; formula •
for coupled position)

Sorting and Tolerance Checking

Measurement Series

SPC Statistical Process Control

=

= >

To sort the parts, the ND 287 compares
the displayed value with an upper or lower
sorting limit, and displays the sorting
result in color in the status display as a
value or with one of the symbols < = >.
In addition, a corresponding signal is
available at switching output X41. Press
the TOLERANCE CHECKING soft key to
open the form for defi ning the sorting
parameters and the sorting limits.

The sorting and tolerance checking
function is always effective for the
currently displayed value, also when
measurement series, minimum/
maximum display, SPC or coupled
positions are active.

<

Display Freeze

In order to read the display in spite of
quickly changing values, the display can
be frozen. The position value is counted
internally until a new display value is
called. You can freeze the display through
a switching signal "Output measured
value" to X41, the CTRL B command, or
by pressing the PRINT soft key.

The MEASURED VALUE OUTPUT
parameter in the Job Setup menu offers
the following possibilities for settings:

Concurrent Display•
The display value always matches the
measured value.
Frozen Display•
The display remains stopped, but is
updated by every measured value
output.
Frozen/Con. Display•
The display is only stopped during
measured value output.

The ND 287 can store measurement
series with up to 10 000 measured
values. They can be evaluated internally
or they can be read out in a block.

Setup Series of Measurements

Measured-value recording through the •
ENTER key, an external signal or
sampling intervals.
Number of measured values.•
Defi nition of sampling intervals (20 ms •
to 60 s) and time slot.

Start Measurement Series

By pressing START MEAS. SERIES. •
By sending an external signal to X41.•

Switching-off the ND or starting a
new measurement series deletes the
values of the previously recorded
measurement series.

Stop Measurement Series

Automatic stop when the defi ned •
number of measured values is reached.
By pressing STOP MEAS. SERIES. •

Measurement Series Analysis

The measurement series can be
displayed as

Statistical data•
Diagram•
Measured value table •

Export Measured Values

Press the EXPORT soft key to start
transmission of the measured value table.

Minimum/Maximum Display

During the measurement series you can
press the SELECT DISPLAY soft key to
switch from the actual value display
(ACTL) to the display of the minimum
value (MIN), the maximum value (MAX)
or the difference between minimum and
maximum value (DIFF).

For Statistical Process Control, the
ND 287 can store up to 1 000 measured
values in a non-volatile FIFO memory.

SPC Setup

Number of samples and data per •
sample.

If you change these values, the
data in the FIFO memory will be
deleted.

Upper and lower tolerance limits •
(same as sorting limits) and nominal
value.
Control limits for control charts.•
Distribution (symmetrical, left-hand or •
right-hand limit).
Measured-value recording through the •
ENTER key or an external signal.

Record SPC Values

Press the START SPC soft key to start •
data acquisition for SPC.
Press the STOP SPC soft key to •
interrupt the SPC function. The
ND 287 is then available for other
measuring tasks.
Press the START SPC soft key to •
restart measurement of the defi ned
number of samples.
The sample counter in the message •
line indicates the number of the
current sample being measured, the
number of the measurements
performed and the total number of
samples to be measured.

Before starting a new SPC
measurement, select DELETE
STATISTIC to delete old SPC values
from the FIFO memory.

SPC Analysis

While the data is being measured, the
ND can display the current status as

Axis Coupling

Input X2 is available for an additional
input assembly (option). Possible options:

Encoder module for connecting a •
second encoder
Analog module for connecting an •

analog sensor with ± 10 V
Descriptions are included with the
modules.

X1 and X2 can be displayed separately
or they can be coupled through
mathematical functions. You can switch
the display by soft key or through a
switching input at any time.

The following axis displays are possible:

Input X1•

Input X2•

Sum of X1 and X2•

Difference between X1 and X2•

Any function for coupling X1 and X2•

Special features of coupled

positions

If PRESET is used, X1 is set to the •

value entered, and X2 is set to zero.

If RESET is used, a value other than •

zero may be displayed depending on

the programmed formula (e.g.: 5 if

"X1 + X2 + 5").

The values of the currently active axis •

display are used for SPC.

If two axes are coupled, the fi ner of •

the two display resolutions will be

used.

If axis values are used as divisors, •

division by zero or display overfl ow

may cause a temporary error

message.

If an analog sensor is connected to •

input X2 and the ENCODER TYPE

fi eld under Encoder Setup, Input X2 is

set to COMPENSATION, the ND 287

behaves in the same way as a

single-axis display unit.

If COMPENSATION is selected, the •

formula for axis-error compensation is

determined automatically. You only

enter the coeffi cient of expansion and

the reference temperature.

Danger to internal components!

The power supply of external circuits must comply with EN 50• 178 requirements for
low voltage electrical separation.
Connect inductive loads only with a • quenching diode parallel to the inductance.
Use only shielded cables.• Connect the shield to the connector housing.

In the Distance-To-Go operating mode, the switching outputs A1 (pin 15) and A2

(pin 16) are based on switching ranges.
