§
User Constant Structure and Three Access Levels
The VG5 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 levels for the
user constants are shown in Table 1.3.
Level
Mode
Groups
Functions
Constants
The VG5 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
Basic
Advanced
In general, press the DATA/ENTER key to move from an upper to a lower level. This varies somewhat, however,
according to the access level, as shown in Figure. 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/ENTER key first leads to the Group
level.

Table 1.3 Access Levels for User Constants
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.
Auto-Tuning: For automatic calculation or setting constants. (Only under the Vector
Control mode.)
Modified Constants: For referencing or monitoring changed constants after shipment.
Classified by application.
Classified by function. (See user constants.)
Individual user constant settings.
Reads/sets user constants required for trial operation. (factory setting)
Reads/sets user constants that are commonly used.
Reads/sets all the user constants that can be used.
