Fieldbus control with fieldbus adapter 327
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 section
Attach the optional fieldbus module on page 35, and the module manual.
The communication between the drive and the fieldbus adapter module is activated
by setting parameter 9802 COMM PROT SEL to EXT FBA. The adapter-specific
parameters in group 51 EXT COMM MODULE must also be set. See the table below.
After the module configuration parameters in groups 51 EXT COMM MODULE, 54
FBA DATA IN and 55 FBA DATA OUT have been set, the drive control parameters
(shown in section Drive control parameters on page 328) must be checked and
adjusted when necessary.
