Functional Description
Introduction Chapter 5 contains a general description of the functionality of the 1395
drive. This description is intended to provide sufficient background
information to support other procedures in this manual and to enable the
reader to:
•
Configure the parameters of the drive.
•
Interface the drive with peripheral devices such as an Allen-Bradley PLC,
discrete operators I/O and the Programming Terminal.
This chapter is not intended to be an all encompassing technical description
of the 1395 drive.
Terminology Following is a brief description of new terms and concepts covered in
Chapter 5.
Configuration The process of linking Sink to Source parameters.
Fast Parameter Fast parameters are all parameters whose values are
updated every 4msec, and are used for the
real time data input and output of the drive. Fast
parameters are backed up in volatile memory only.
Interface Hardware and associated software required to
transfer information and/or control signals from one
device to another.
Microbus Hardware and associated software designed by
Allen-Bradley for the exchange of digital
information at the microprocessor level. The
Microbus is used for the transfer of information
between Adapter Boards and the Main Control
Board.
Port Hardware located on the Main Control Board which
allows for connection of one Adapter Board to the
Microbus. There are two ports on the Main Control
Board.
Parameter Memory location used to store drive data. Each
parameter is given a number called the parameter
number. The parameter value may be specified in
decimal or hexadecimal. When specified in
hexadecimal, the word “Hex” will appear after the
parameter value.
