Features
The features of the adapter include the following:
• Typical mounting in a PowerFlex 7-Class drive.
• Captive screws to secure and ground the adapter to the drive.
• Compatibility with various configuration tools to configure the adapter
and connected host drive, including the following tools:
– PowerFlex HIM (Human Interface Module) on the drive, if available
– Connected Components Workbench software, version 1.02 or later
– DriveExplorer software, version 2.01 or later
– DriveExecutive software, version 3.01 or later
• Rotary switches to set a rack address before applying power to the
PowerFlex drive. Or, you can disable the switches and use an adapter
parameter to set the rack address.
• DIP switches to configure the adapter for starting module group, last/not
last RIO group within the rack, 1/4 or 1/2 rack, and baud rate. Or, you
can disable the switches and use adapter parameters to configure the
adapter.
• Status indicators that report the status of the drive communications, the
adapter, and network. They are visible when the drive cover is open or
closed.
• Parameter-configured I/O (Logic Command/Reference and up to four
pairs of Datalinks) to accommodate application requirements. The
adapter can be configured to use a 1/4 rack (two 16-bit words) or 1/2
rack (four 16-bit words) of discrete I/O. Additionally, up to eighteen
16-bit words of I/O can be transferred using the Block Transfer I/O

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. DPI
or SCANport host products must not be directly connected
together using 1202 cables. Unpredictable behavior due to timing
and other internal procedures can result if two or more devices
are connected this way.
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
I/O 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 faulted controller).
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.

Before installing the adapter, verify that you have all required equipment.
See Required Equipment
Remote I/O adapters are connected to the Remote I/O network or link with
twinaxial cable used for Remote I/O and Data Highway Plus (DH+)
communications. When selecting a cable, remember these points:
• Only 1770-CD Belden #9463 is tested and approved for Remote I/O and
DH+ installations. Use other cables at your own risk.
• The maximum cable length depends on the baud rate.
Baud Rate Maximum Cable Length
57.6 Kbps 3,048 m (10,000 ft)
115.2 Kbps 1,524 m (5,000 ft)
230.4 Kbps 762 m (2,500 ft)
• All three connectors (blue, shield, and clear) must be connected at each
node.
• Do not use a star topology. Only two cables may be connected at any
wiring point. You can use a series topology and daisy-chain two wires at
a point.

Commissioning the Adapter
To commission the adapter, set the Rack Address Rotary Switches and the
Configuration DIP Switches. Either set these switches to the desired
settings or disable them by sliding Configuration DIP Switches SW7 and
SW8 to the ‘On’ position so that adapter parameters can be used instead.
Important: New switch settings are recognized only when power is applied
to the adapter or it is reset. After you change a switch setting,
cycle power or reset the adapter.
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 equipment damage exists. Pen ink or
pencil lead may damage the adapter switches. Do not use a pen or
pencil to set the switches.
Setting the Rack Address Rotary Switches
The adapter accepts a rack address between 00 and 77 octal. The default
setting is 01. See Table 3.A on page 3-3
of the octal address to be used. Set the Rack Address Rotary Switches

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).
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 in which the
20-COMM-R 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.

Using the PowerFlex 7-Class HIM to Access Parameters
If your drive has either an LED or LCD HIM (Human Interface Module), it
can be used to access parameters in the adapter as shown below. We
recommend that you read through the steps for your HIM before performing
the sequence. For additional information, see the drive documentation or the
PowerFlex 7-Class HIM Quick Reference, publication 20HIM-QR001.
Using an LED HIM
Step Example Screens
1. Press the key and then the Device (Sel) key to
display the Device Screen.
2. Press the or key to scroll to the adapter.
Letters represent files in the drive, and numbers represent
ports. The adapter is usually connected to port 5.
3. Press the (Enter) key to enter your selection.
A parameter database is constructed, and then the first
parameter is displayed.
4. Edit the parameters using the same techniques that you use
to edit drive parameters.

Setting the Rack Address
If adapter Configuration DIP Switches SW7 and SW8 (Figure 2.2) are both
set to ‘On’, the value of Parameter 03 - [RIO Addr Cfg] determines the
rack address. Note these points:
• Although the adapter supports rack addresses between 00 and 77 octal,
not all controllers recognize all of the addresses, and a Remote I/O
channel can support only 32 devices.
• PLC-2 controllers identify rack addresses differently than other
controllers. PLC-2 controllers identify the adapter rack address as one
plus the value of the parameter setting.

The rack address must be unique.

2. Set the value of Parameter 03 - [RIO Addr Cfg] to the decimal
equivalent of the octal address to be used.
The address is entered and displayed as a decimal value, but is
internally converted to an octal address.
Important: The HIM and software tools, such as DriveExplorer or
DriveExecutive, will display the address as a decimal value.
3. Reset the adapter (see Resetting the Adapter
on page 3-8).
