3. Verify that drive Parameter 213 - [Speed Ref Source] is reporting that
the source of the Reference to the drive is ‘22’ (DPI Port 5).
This ensures that any Reference commanded from the network can be
monitored by using drive Parameter 002 - [Commanded Speed]. If a
problem occurs, this verification step provides the diagnostic capability
to determine whether the drive/adapter or the network is the cause.
TIP: For PowerFlex 750-Series drives, use drive Parameter 545 -
[Speed Ref A Sel] to set the drive speed Reference:
a. Set the Port field to ‘Port 0 - PowerFlex 75x’.
b. Set the Parameter field to point to the port in which the
20-COMM-L adapter/20-750-20COMM Communication Carrier
Card are installed (for example, ‘876 - Port 6 Reference’).
The number ‘876’ in the Parameter filed of the example is the
parameter in the drive that points to the port.
