I – 1 ND 287 position displa
y unit
 Series of measurements:
 Sorting measured values and finding the Minimum, Maximum,
Sum, Difference or a definable coupled position value.
Displaying the sorting results in order to intervene, if necessary.
 Memory capacity for series of measurements: Up to 10 000
measured values per axis.
 Analysis of series of measurements: Arithmetical mean value,
standard deviation,
graphical representation of all measured
values with minimum, maximum and mean value of the series of
measurements.
 Measured-value acquisition by external signal or selectable
sampling interval,
or by pressing the ENTER key.
 Statistical Process Control (SPC)
:
 Calculation of arithmetical mean value, standard deviation and
range
. Displaying graphs or histograms with symmetrical or
asymmetrical density function .
 Process capability indices c
p
and c
pk
, quality control charts for
mean value, standard deviation and range.
 Measured-value acquisition by external signal or by pressing the
ENTER key.
 FIFO memory capacity: Up to 1000 measured values.
 There are two serial ports for transmitting measured values,
compensation values or configuration parameters to a PC or printer:
The data can be transferred via the RS 232-C/V.24 or the USB Type
B (UART)
interface. It is also possible to download software via the
serial interface.
 Diagnostic functions
for testing the encoder, the keyboard, the
screen, the supply voltage and the switching inputs/outputs.
 On the ND 287, one measured value can be displayed in large
characters on the screen
at any one time. If two encoders are
connected to the ND, you can switch the display from the position
value supplied by the first encoder to the position value supplied by
the second encoder, or to a defined coupled position value.
 The integrated help system provides information and assistance in
any situation.
