Safety Precautions Please read the following safety precautions carefully.
!
ATTENTION: Risk of injury or death exists. The PowerFlex
drive can 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 the
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 can 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 can fault
when you reset the adapter. Determine how your drive responds
before resetting an adapter.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 9 - [Comm Flt Action] and 10 - [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, take
precautions 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 can 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.

6 Apply power to the Profibus master and other devices on the
network.
Verify that the master and network are installed properly and
functioning in accordance with Profibus standards.

8 Create a ladder logic program.
Use a controller configuration tool to create a ladder logic
program that enables you to do the following:
•Control the connected drive, via the adapter, by using I/O.
•Monitor or configure the drive using explicit messages.

Installing the Adapter
This chapter provides instructions for installing the adapter in a PowerFlex
7-Class drive.
Preparing for an Installation Before installing the adapter, verify that you have all required equipment.
See Required Equipment on page 1-3.
Commissioning the Adapter To commission the adapter, you must set a unique node address on the
network. See Setting the Node Address Switches on page 2-2 or 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.

2-2 Installing the Adapter
PowerFlex 20-COMM-P Profibus Adapter User Manual
Publication 20COMM-UM006B-EN-P
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 Profibus 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.
Figure 2.1 Setting Adapter Node Address Switches
The Node Address switch settings can be verified by viewing Parameter 04
- [P-DP Addr Actual] or Diagnostic Device Item numbers 27 and 28
(page 7-4) with any of the following drive configuration tools:
•PowerFlex HIM
•Connected Components Workbench software, version 1.02 or later
•DriveExplorer software, version 2.01 or later
•DriveExecutive software, version 3.01 or later
Setting Description
0…99 The node address used by the adapter if the Node Address switches are enabled.
The default switch setting is 05.
Important: If the Node Address switches are set to ‘00’, the adapter uses the value
stored in Parameter 03 - [P-DP Addr Cfg] for the node address. See Setting the Node
Address on page 3-3.

Connecting the Adapter to
the Drive
1. Remove power from the drive.
2. Use static control precautions.
3. Remove or open the drive cover.
4. Connect the Internal Interface cable to the DPI port on the drive and
then to the DPI connector on the adapter (see Figure 2.2).
5. Secure and ground the adapter to the drive (see Figure 2.3) by doing the
following:
–On a PowerFlex 70 drive, fold the Internal Interface cable behind the
adapter and mount the adapter on the drive using the four captive
screws.
–On a PowerFlex 700, PowerFlex 700H, or PowerFlex 700S drive,
mount the adapter on the drive using the four captive screws.
Important: Tighten all screws to properly ground the adapter.
Recommended torque is 0.9 N•m (8.0 lb•in).
!
ATTENTION: Risk of injury or death exists. The PowerFlex
drive may contain high voltages that can cause injury or death.
Remove power from the drive, and then verify power has been
discharged before installing or removing the adapter.
