Fieldbus control 345ABB control profiles technical data OverviewABB Drives profileThe ABB Drives profile provides a standard profile that can be used on multipleprotocols, including Modbus and the protocols available on the FBA module. Twoimplementations of the ABB Drives profile are available:• ABB DRV FULL – This implementation standardizes the control interface withACS600 and ACS800 drives.• ABB DRV LIM – This implementation standardizes the control interface withACH400 drives. This implementation does not support two control word bitssupported by ABB DRV FULL .Except as noted, the following “ABB Drives profile” descriptions apply to bothimplementations.DCU profileThe DCU profile extends the control and status interface to 32 bits, and is the internalinterface between the main drive application and the embedded fieldbusenvironment.Control wordThe CONTROL WORD is the principal means for controlling the drive from a fieldbussystem. The fieldbus master station sends the CONTROL WORD to the drive. The driveswitches between states according to the bit-coded instructions in the CONTROLWORD. 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 controllingcommands (set using parameters 1001 EXT1 COMMANDS, 1002 EXT2COMMANDS and 1102 EXT1/EXT2 SEL).• The serial communication channel used is configured to use an ABB controlprofile. For example, to use the control profile ABB DRV FULL , requires bothparameter 9802 COMM PROT SEL = 1 (STD MODBUS), and parameter 5305 EFBCTRL PROFILE = 2 (ABB DRV FULL ).
