Fieldbus control 245
Setting up communication through a fieldbus adapter
module
Before configuring the drive for fieldbus control, the adapter module must be
mechanically and electrically installed according to the instructions given in the
User’s Manual of the appropriate fieldbus adapter module.
The communication between the drive and the fieldbus adapter module is activated
by setting parameter
50.01 Fba enable to Enable . The adapter-specific parameters
must also be set. See the table below.
