Safety Precautions
Please read the following safety precautions carefully.
ATTENTION: Risk of injury or death exists. The PowerFlex
drive may contain high voltages that can cause injury or death.
Remove all power from the PowerFlex drive, and then verify
power has been discharged before installing or removing an
adapter.
ATTENTION: Risk of injury or equipment damage exists. Only
personnel familiar with drive and power products and the
associated machinery should plan or implement the installation,
start up, configuration, and subsequent maintenance of the
product using an adapter. Failure to comply may result in injury
and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The adapter
contains electrostatic discharge (ESD) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static
control precautions are required when handling the adapter. If
you are unfamiliar with static control procedures, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.
ATTENTION: Risk of injury or equipment damage exists. If the
adapter is transmitting control I/O to the drive, the drive may fault
when you reset the adapter. Determine how your drive will
respond before resetting an adapter.
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
communication is disrupted or the controller is idle. By default,
these parameters fault the drive. You can set these parameters so
that the drive continues to run, however, precautions should be
taken to verify that the settings of these parameters do not create
a risk of injury or equipment damage. When commissioning the
drive, verify that your system responds correctly to various
situations (for example, a disconnected cable or a controller in
idle state).
ATTENTION: Risk of injury or equipment damage exists.
When a system is configured for the first time, there may be
unintended or incorrect machine motion. Disconnect the motor
from the machine or process during initial system testing.
ATTENTION: Risk of injury or equipment damage exists. The
examples in this publication are intended solely for purposes of
example. There are many variables and requirements with any
application. Rockwell Automation does not assume responsibility
or liability (to include intellectual property liability) for actual
use of the examples shown in this publication.

Setting the Node Address
Switches
Set the adapter Node Address switches (Figure 2.1) by rotating the switches
to the desired value for each digit.
Important:Each node on the ControlNet network must have a unique
address. Set the node address before power is applied because
the adapter uses the node address it detects when it first
receives power. To change a node address, you must set the new
value and then remove and reapply power to (or reset) the
adapter.

Applying Power
ATTENTION: Risk of equipment damage, injury, or death
exists. Unpredictable operation may occur if you fail to verify
that parameter settings are compatible with your application.
Verify that settings are compatible with your application before
applying power to the drive.
Install the drive cover or close the drive door, and apply power to the drive.
The adapter receives its power from the connected drive. When you apply
power to the adapter for the first time, its topmost ‘PORT’ status indicator
should be steady green or flashing green after an initialization. If it is red,
there is a problem. See Chapter 7
Start-Up Status Indications
Status indicators for the drive and communication adapter can be viewed on
the front of the drive (Figure 2.6
start-up status indications are shown in Table 2.A

Configuring and Verifying Key Drive Parameters
The PowerFlex 7-Class drive can be separately configured for the control
and Reference functions in various combinations. For example, you could
set the drive to have its control come from a peripheral or terminal block
with the Reference coming from the network. Or you could set the drive to
have its control come from the network with the Reference coming from
another peripheral or terminal block. Or you could set the drive to have both
its control and Reference come from the network.
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed
Reference to ‘22’ (DPI Port 5).
Installing the Adapter2-9
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.
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.
Commissioning the Adapter
To commission the adapter, you must set a unique node address on the
network. See Setting the Node Address
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.
