Setting up the embedded fieldbus interface
Set the drive up for the embedded fieldbus communication with the parameters shown
in the table below. The Setting for fieldbus control column gives either the value to
use or the default value. The Function/Information column gives a description of the
parameter.

COMMUNICATION INITIALIZATION
Initializes embedded fieldbus commu-
nication. Drive-to-drive link operation
is automatically disabled.

Defines the action taken when a com-
munication loss is detected.
Fault (default)58.14 Communication loss
