the instructions given in the
User’s manual of the module.
2. Power up the drive.
3. Enable the communication between the drive and the fieldbus adapter module
with parameter
50.1 FBA A enable .
4. With 50.2 FBA A comm loss func , select how the drive should react to a fieldbus
communication break.
Note: This function monitors both the communication between the fieldbus
master and the adapter module and the communication between the adapter
module and the drive.
5. With 50.3 FBA A comm loss t out , define the time between communication
break detection and the selected action.
6. Select application-specific values for the rest of the parameters in group 50
Fieldbus adapter (FBA) , starting from 50.04 . Examples of appropriate values
are shown in the tables below.
7. Set the fieldbus adapter module configuration parameters in group 51 FBA A
settings . As a minimum, set the required node address and the control profile.
8. Define the process data transferred to and from the drive in parameter groups
52 FBA A data in and 53 FBA A data out .
Note: Depending on the communication protocol and profile being used, the
Control word and Status word may already be configured to be sent/received
by the communication system.
9. Save the valid parameter values to permanent memory by setting parameter
96.7 Parameter save manually to Save .
10. Validate the settings made in parameter groups 51, 52 and 53 by setting
