2. If hard-wired discrete digital inputs are not used to control the drive,
verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and
362 - [Dig In2 Sel] are set to ‘0’ (Not Used).
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.
Commissioning the Adapter To commission the adapter, you must set a unique node address on the
network. See
Setting the Node Address on page 3-3 for details.
Important: New settings for some adapter parameters are recognized only
when power is applied to the adapter or it is reset. After you
change parameter settings, cycle power or reset the adapter.
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 (slot) in which the
20-COMM-C adapter/20-750-20COMM Communication Carrier
Card are installed (for example, ‘876 - Port 6 Reference’).
The number ‘876’ in the Parameter field of the example is the
parameter in the drive that points to the port.
