Control word and Status word

The Control word 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.
The contents of the Control word and the Status word are detailed on pages
413 respectively. The drive states are presented in the state diagram (page 414).
