Communication interfaces 183
Setting up the inverter for fieldbus control
1. Install the fieldbus adapter module mechanically and electrically according to the
instructions given in the User's manual of the module.
2. Power up the inverter.
3. Enable communication between the inverter and the fieldbus adapter module with
parameter 150.31 FBA B Enable.
4. Select how the inverter should react to a fieldbus communication break with parameter
150.32 FBA B comm loss func.
Note: This function monitors both the communication between the fieldbus
master and the adapter module, and the communication between the adapter
module and the inverter.
5. Define the time between communication break detection and the selected action with
parameter 150.33 FBA B comm loss t out.
6. Select application-specific values for the rest of the parameters in group 150 FBA.
7. Set the fieldbus adapter module configuration parameters in group 154 FBA B
settings. As a minimum, set the required node address and the control profile. Set
profile to transparent 16 mode.
Note: The parameter indices and names vary depending on the fieldbus
adapter in use.
8. Define the process data transferred to and from the inverter using parameter groups
155 FBA B data in and 156 FBA B data out or use direct addressing.
9. Save valid parameter values to permanent memory by setting parameter 196.07
Param save manually to save.
10. Validate the settings in parameter groups 154 FBA B settings, 155 FBA B data in and
156 FBA B data out by setting parameter 154.27 FBA par refresh to configure.
