Rockwell Automation 1305 AC Drive, Series A and B, Firmware 4.xx-5.xx - Manual (Page 150)

Appendix B – Serial Communications
B-2
LOGIC CONTROL DATA
The information in Table B.2 provides the Logic Control
information that is sent to the drive through the logic
controllers output image table. When using the Bulletin
1203-GD1 communication module, this information is sent to
the drive when dip switch No. 2 of SW3 is enabled.
DRIVE STATUS DATA
The information in Table B.3 provides the Drive Status
information that will be sent to the logic controllers input
image table from the drive. When using the Bulletin 1203-GD1
communication module this information will be sent to the PLC
from the drive when switch No. 2 of SW3 is enabled.
PARAMETER GROUPS/USER SETTINGS
The information in Table B.4 provides a listing of all drive
parameters.
The column entitled ‘‘Display Units” are the units that will
appear on the Human Interface Module.
Since certain parameters have different resolution than others, a
scale factor is required to convert the “Display Units” value to
a decimal value that will be displayed in the controller’s I/O
image tables. The column marked “Drive Units Scale Factor” is
provided to perform this conversion.
SCALE FACTOR CONVERSION
When Reading parameter data in the controller’s input image
table, divide this value by the “Drive Units Scale Factor” to
determine the ‘‘Display Units.”
When Writing parameter data from the controller’s output
image table to the drive, the value entered into the output
image table should be the required “Display Units” value
multiplied by the “Drive Units Scale Factor”.
“Display Unit” equivalent to Parameter Text Descriptions.
Some parameters use a text description in the place of
numerical “Display Units”. The information in Table B.5
provides the decimal equivalent to the text descriptions.
