Overview
ABB drives profile
The ABB Drives profile provides a standard profile that can be used on multiple
protocols, including Modbus and the protocols available on the FBA module. Two
implementations of the ABB Drives profile are available:
•
ABB
DRV
FULL
– This implementation standardizes the control interface with
ACS600 and ACS800 drives.
•
ABB
DRV
LIM
– This implementation standardizes the control interface with
ACH400 and ACH550 drives. This implementation does not support two control
word bits supported by
ABB
DRV
FULL
.
Except as noted, the following “ABB Drives Profile” descriptions apply to both
implementations.
DCU profile
The DCU profile extends the control and status interface to 32 bits, and is the
internal interface between the main drive application and the embedded fieldbus
environment.
Control Word
The
CONTROL
WORD
is the principal means for controlling the drive from a fieldbus
system. The fieldbus master station sends the
CONTROL
WORD
to the drive. The drive
switches between states according to the bit-coded instructions in the
CONTROL
WORD
. Using the
CONTROL
WORD
(ABB Drives profile version) requires that:
•
The drive is in remote (
REM
) control.
•
The serial communication channel is defined as the source for controlling
commands (set using parameters 1001
EXT
1
COMMANDS
, 1002
EXT
2
COMMANDS
and 1102
EXT
1/
EXT
2
SEL
).
•
The serial communication channel used is configured to use an ABB control
profile. For example, to use the control profile
ABB
DRV
FULL
, requires both
parameter 9802
COMM
PROT
SEL
= 1 (
STD
MODBUS
), and parameter 5305
EFB
CTRL
PROFILE
= 2 (
ABB
DRV

).
