Fieldbus control through a fieldbus adapter 257
Setting up the drive 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 drive.
3. Enable the communication between the drive and the fieldbus adapter module
with parameter 50.01 FBA A enable.
4. With 50.02 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 50.03 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 communication
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
96.07 Parameter save manually to Save.
10. Validate the settings made in parameter groups 51, 52 and 53 by setting
parameter 51.27 FBA A par refresh to Configure.
11. Configure control locations EXT1 and EXT2 to allow control and reference signals
to come from the fieldbus. Examples of appropriate values are shown in the
tables below.
