Control Description
Chapter Content Chapter 3 contains a general description of the 1395 Digital
Reference Adapter Board program. This description is intended to
provide sufficient background information to support other
procedures in this manual and to assist the reader on:
• Understanding how to configure the board
• Understanding how to interface the board with discrete I/O.
• Understanding how to configure the Analog I/O for the RTP
application.
Parameter Overview Important: All Setup and configuration parameters are normally
saved in the EEPROM of the Main Control Board. Nor-
mally, there will be no need to completely load-in a full
set of parameters for both the basic Drive and the Digital
Reference Adapter Board.
Should there be a need to check or download parameters to the Drive,
use of the ITS device will prove to be one of the most efficient
methods.
The Digital Reference Adapter Board contains two normal types of
parameters, Configurable and Set-Up. Configuration Parameters
control and monitor the run-time operation of the Drive, while Set-Up
parameters program the Reference Adapter Board functions. One
other type of “read only” Parameter is brought out to the RS422 port
(normally for the Hand Held Terminal (DHT) or for the Intelligent
Terminal System (ITS), so the internal strategic variables can be
monitored, but not modified. Additional information concerning the
use of these parameters is included in Chapter 5.
All of the parameters are listed in Table 8-1, which also contains
detailed definitions for each of the parameters. The Digital Reference
Adapter has 10 Configuration Parameters and 37 Set-Up Parameters.
Programming the Set-Up Parameters is accomplished with the
Bulletin 1395 Programming Terminal or through another intelligent
device connected to the Drive such as a PLC. The Set-Up Parameters
have defaults for the application which in most cases will not require
changing during start up. Refer to the Bulletin 1395 Installation &
Maintenance Manual for an explanation of programming techniques.
All adapter Parameters are referenced by a unique Drive system
parameter number. The RTP Unwind Drive application always
utilizes the Digital Reference Adapter Board in the Port A position.
For this reason, only Port A Parameters are listed in Chapter 8. The
board should not be installed in Port B.
