PROFIdrive communication profile
￭ Control word and Status word
The Control word (PROFIdrive parameter 967) is the principal means for controlling the
drive from a fieldbus system. It is sent by the fieldbus master station to the drive through
the adapter module. The drive switches between its states according to the bit-coded
instructions in the Control word and returns status information to the master in the Status
word (PROFIdrive parameter 968).
The contents of the Control word and the Status word are detailed below. See the drive
documentation for information on the drive-specific bits. The drive states are presented on
page 78. The drive states for the positioning mode are presented on page 78.
