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 master 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 master in the Status
Word. For more information see the Firmware manual of the drive.
