The Fieldbus Control Interface - ABB ACS800 Firmware Manual

The fieldbus control interface

The communication between a fieldbus system and the drive employs data sets.
One data set (abbreviated DS) consists of three 16-bit words called data words
(DW). The Crane control program supports the use of four data sets, two in each
direction.
The three data sets for controlling the drive are referred to as the Main Reference
data set, the Auxiliary1 Reference data set, and the Auxiliary2 Reference data set.
The source from which the drive reads the Main and Auxiliary Reference data sets is
defined with parameter 90.07. The contents of the Main Reference data set are
fixed. The contents of the Auxiliary Reference data sets can be selected using
parameters 90.01, 90.02, 90.03, 90.04, 90.05 and 90.06.
The three data sets containing actual information on the drive are referred to as the
Main Actual Signal data set, the Auxiliary1 Actual Signal data set, and the Auxiliary2
Actual Signal data set. The contents of these data sets are partly selectable with the
parameters in group 92.

*The index number is required when the data word allocation to process data is
defined via the fieldbus parameters in group 51. This function is dependent on the
type of the fieldbus adapter.
**With the Generic Drive communication profile active, Actual 1 is fixed to the actual
signal 01.02 SPEED (in DTC motor control mode) or 01.03 FREQUENCY (in scalar
mode).
The update time for the Main Reference and the Main Actual Signal data sets is 6
milliseconds, and for the Auxiliary Reference and the Auxiliary Actual Signal data
sets it is 100 milliseconds.
