The ND 287 position display unit from HEIDENHAIN is designed for
measuring devices, adjustment and testing equipment, automated
tasks, as well as infeed and positioning tasks with up to two axes that
can be moved manually.
Linear/angular/rotary encoders, length gauges or analog sensors can
be connected to the ND 287. The ND 287 features two slots for the
connection of modular input assemblies:
 An encoder module for connecting an incremental photoelectrical
HEIDENHAIN encoder with sinusoidal 11 µApp, 1 Vpp signals or an
absolute HEIDENHAIN encoder with bidirectional EnDat interface
(purely serial) is a standard item supplied with the position display
unit.
 Optional modules that can be easily adapted to the ND's
requirements:
 Second encoder module for connecting a HEIDENHAIN encoder
with 11 µApp, 1 Vpp or EnDat interface (purely serial) or
 Analog module
for connecting an analog sensor with ±10 V
interface, primarily a temperature sensor for axis-error
compensation
 Sorting and tolerance checking function with capacity for saving
the tolerances of 10 parts
The following functions are available on the ND 287:
 Multilingual user guidance: Language can be selected by the user
 REF reference-mark evaluation for distance-coded or single
reference marks
 Display of position value (length or angle), traversing speed for
series of measurements or other measured values from analog
sensors
 Distance-To-Go or Actual Value operating mode
 Two datums
 Scaling factor
 Stopwatch
 Reset or Preset function, also through external signal
 Linear or non-linear error compensation for axis-error
compensation
 Switching inputs and outputs
