GEH-6412 Toolbox for AV-300i Version 2 Drive Chapter 4 Configuring an AV-300i Version 2 Drive •••• 4-15
Concepts
The following section defines items and features used when configuring an AV-300i
Version 2 drive. When a drive is created, the Work Area displays as follows:
The drive name
can be modified.
Main Menu contains
the configurable items.
Click to display a drawing of the
block diagram and signal flow.
Parameters, located with the Main Menu, allow you to configure the drive behavior.
Each parameter has a name with up to 20 characters, which identifies it and helps to
convey its use. A parameter also can have units, such as RPM, displayed with the
toolbox and keypad. The unit field is limited to five characters. Each parameter
contains a value, which can be a number or a setting. The value is adjusted to modify
the drive behavior. Examples of basic parameters and their associated units are
Motor rated current (Amps), Motor rated freq (Hz), Motor rated voltage (Volts), and
Regulator type. Parameters can be set and modified from the Outline View under the
items Main Menu or Block diagram, or from a Wizard or the keypad.
Variables, similar to parameters, have a name up to 20 characters and a 5-character
unit field. However, unlike parameters, you cannot change variables. They are
changed by the drive as a result of the execution of the pattern within it. For
example, the variable Speed feedback (RPM ) gets updated on a continuous basis and
represents the drives actual speed.
Block diagrams provide an overall picture of signal flow, sequencing and regulator
control in the drive. While communicating with the drive, the diagrams display drive
variables and their real time values. Contact and coil states are also indicated. Certain
drive parameters can be modified from this view (refer to the section, Block
Diagrams).
