Operating Parameters
Operating parameters allow you to modify the operating
characteristics of your display unit and define the evaluation
of the encoder signals. Operating parameters that can be
changed by the user are called user parameters, and can be
accessed with the SPEC FCT key and the dialog “PARA-
METER” (user parameters are identified as such in the
parameter list). The full range of parameters can only be
accessed through the dialog “CODE“ and by entering 95148.
Operating parameters are designated by the letter P and a
number. Example: P11. The parameter designation is shown
in the input field when you select it with the DATUM and
ENT key in the X display. The parameter setting is shown in
the Y display.
Some operating parameters have separate values for each
axis. Such parameters have an additional index number from
1 to 3 with the ND 760 and from 1 to 2 with the ND 720.
Operating parameters with an index number can be selected
with the axis-direction keys.
Example: P12.1 scaling factor, X axis
P12.2 scaling factor, Y axis
P12.3 scaling factor, Z axis (ND 760 only)
The operating parameters are preset before the unit leaves
the factory. These factory default settings are indicated in the
parameter list in boldface type.
