The Control Word and the Status Word

The Control Word is the principal means for controlling the drive
from a fieldbus system. It is sent by the fieldbus client station to
the drive through the adapter module. The drive switches between
its states according to the bit-coded instructions on the Control
Word and returns status information to the client in the Status
Word.
The contents of the Control Word and the Status Word are
detailed in Tables
presented in the ABB Drives Profile state machine

References

References are 16-bit words containing a sign bit and a 15-bit
integer. A negative reference (indicating reversed direction of
rotation) is formed by calculating the two's complement from the
corresponding positive reference.
ABB drives can receive control information from multiple sources
including analogue and digital inputs, the drive control panel and a
communication module (eg, FENA-01). In order to have the drive
controlled through the fieldbus, the module must be defined as the
source for control information, eg, Reference.
