User Constant Structure and Three Access Levels
User Constant Structure and Three Access Levels
The
Y
D3
000
N
has
a
number
of
user
constants
for
setting
various
functions.
These
user
constants
are
classified
into a hierarchy to make them easier to use.
The levels are as follows from top to bottom: Modes, Groups, Functions, and Constants. The access
levelsfor the user constants are shown in Table 1.3.

Mode
Classified according to operation
Operation:
For operating the Inverter. (All kinds of monitoring are possible.)
Initialize:
For selecting the language displayed at the Digital Operator, setting
access levels, initialization, and the control modes.
Programming:
For setting user constants for operation.
Autotuning:
For automatic calculation or setting motor constants. (Only under
the vector control mode.)
Modified constants:
For referencing or changing user constants after shipping.
Groups
Classified by application.
Functions
Classified by function. (See user constants.)
Constants
Individual user constant settings.
The
Y
D3
000
N
allows
the
following
three
access
levels
to
be
set
in
order
to
further
simplify
setting
user
constants.
(An
access
level
is
a
range
of
user
constants
that
can
be
referenced
or
set.)
Quick-Start
Reads/sets user constants required for trial operation. [Factory setting]
Basic
Reads/sets user constants that are commonly used.
Advanced
Reads/sets all the user constants that can be used.
In general, press the DATA / ENTER Key to move from an upper to a lower level. This varies
somewha
t
, however, according to the access level, as shown in Fig. 1.1. For the Quick-Start
access level, which has few user constants that can be set , pressing the DATA/ENTER Key
jumps directly to the user constant level;whereas for the Advanced access level, which has
many user constants, pressing the DATA / ENT
ERKey first leads to the Group level.
