Concepts
The following section defines items and features used when configuring an AVDV
Series 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 here to display a
drawing of the block diagram
and signal flow.
Parameters 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 in order to modify the drive behavior.
Some basic parameters along with 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 Diagram, or from a Wizard or the keypad.
Variables, similar to parameters, have a 20-character name and a 5-character unit
field. However, unlike parameters, the user can not 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.
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).
