 Control word and Status word
The Control word is the principal means for controlling the drive
from a fieldbus system. The fieldbus master station sends the
Control word 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.
The contents of the Control word and the Status word are detailed
below. The drive states are presented on page 87.
