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.
