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 drives documentation for information on drive-
specific bits. The drive states for all operating modes are
. The drive states for the positioning mode
are presented on page
