Chapter 1 Getting Started
Safety Precautions Please read the following safety precautions carefully.
ATTENTION: Risk of injury or death exists. The PowerFlex product may
contain high voltages that can cause injury or death. Remove all power
from the PowerFlex product, and then verify power has been discharged
before installing or removing an option module.
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 drive using the option module. Failure to
comply may result in injury and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The option module
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 option module. 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 option
module is transmitting control I/O to the drive, the drive may fault when
you reset the option module. Determine how your drive will respond
before resetting the module.
ATTENTION: Risk of injury or equipment damage exists. Host
Parameters 33 [Comm Flt Action] and 34 [Idle Flt Action] let you
determine the action of the option module and connected drive if I/O
communication is disrupted, the controller is idle, or Acyclic messaging
for drive control is disrupted. 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.

Chapter 2
Installing the Option Module
This chapter provides instructions for installing the option module in a
PowerFlex® 750-Series product.
Preparing for an
Installation
Before installing the option module, do the following:
• Read the PROFINET Installation Guideline for Cabling and Assembly.
• Verify that you have all required equipment. See Required Equipment on
page 14.
Setting the IP Address
Selection Jumper
The IP Address Selection Jumper (Figure 1) determines the source of the IP
address for the option module. When the jumper is placed on Pins 2 and 3,
either the default network address is used or the network address may be
configured with option module parameters.
When the jumper is in this position, the setting for Device Parameter 18 -
[DHCP] does not have any effect.
The default network address is:
• IP Address 192.168.0.1
• Subnet Mask 255.255.255.0
• Gateway Address 192.168.0.1
If the jumper is on Pins 1 and 2—or there is no jumper—the network address is
configured by DCP/DHCP. If Device Parameter 18 [DHCP] is set to ‘0’
(Disabled), the network address is configured by using a PROFINET controller
with DCP capability. If Device Parameter 18 [DHCP] is set to ‘1’ (Enabled), the
network address is configured from a DHCP server.

Connecting the Option
Module to the PowerFlex
750-Series Product
1. Insert the option module into Port 4, 5, or 6 and tighten the module
mounting screws into the pod mounting bracket. To properly ground the
module to the drive, torque both mounting screws to 0.45...0.67 N•m
(4.0...6.0 lb•in).
2. When another module (I/O, encoder, communication, and so forth)
resides in the adjacent port to the left of the 20-750-PNET2P option
module—and the lower mounting screw of that module is a larger T15
Torx head screw, perform additional steps 2a through 2c. If the port is
empty or the adjacent module already uses the smaller T8 Torx head
mounting screws, save this spare screw for future use.
The 20-750-PNET2P option module is shipped with a small bag
containing a spare T8 Torx head mounting screw. The larger T15 Torx
head mounting screw on the adjacent left module may mechanically
interfere with the clips on the PROFINET cable connector when attached
to the PROFINET module. This may cause problems connecting or
removing the connector. To prevent this, perform the following steps.
a. Remove the adjacent module's lower mounting screw, the T15 Torx
head screw closest to the bottom of the pod mounting bracket.
b. Replace the larger T15 Torx head screw with the smaller spare T8 Torx
head mounting screw.
c. Tighten the mounting screw to the pod mounting bracket to properly
ground the adjacent module to the product. Torque the screw to
0.45...0.67 N•m (4.0...6.0 lb•in).

5. Route the other end of the PROFINET cable from the network through
the bottom of the drive and insert its cable plug into the mating option
module connector.
Using MRP (Media
Redundancy Protocol) for
Ring Topology
A Ring network is a single-fault tolerant network intended for interconnection
of automation devices. MRP (Media Redundancy Protocol), a simple and
deterministic protocol, when enabled in a PROFINET network connected in
Ring Topology achieves reconfiguration time of 200 ms. A maximum of 50
devices can be connected in a ring network by using MRP.
When enabled in ring topology, MRP offers the following advantages:
• Media redundancy
• Higher communication availability
• Reduced number of network components
ATTENTION: Risk of injury or death exists. The PowerFlex 750-Series
product may contain high voltages that can cause injury or death.
Remove power from the drive, and then verify power has been
discharged before connecting the option module to the network.
IMPORTANT PROFINET connectors are available from a variety of sources
and in various sizes. As such, there may be mechanical
limitations that prohibit the use of some connectors. We
recommend the LAPP GROUP connector part number
21700540 for use with PowerFlex 750-Series products.

• Fast network fault detection and reconfiguration
• Resiliency of a single-fault tolerant network
• Easy implementation without any additional hardware requirements
The 20-750-PNET2P option module can only be connected as MRC (Media
Redundancy Client) and will not work as MRM (Media Redundancy Manager).
An MRM capable device needs to be present in the network to achieve the
media redundancy. See Figure 3 for typical connection having MRM and MRC
in a ring network.

The following settings need to be considered for an MRP capable switch/PLC
connected in a ring network:
•CycleTime:128ms
• MRM functionality: Enabled
• Ring ports to be defined
Applying Power
Apply power to the PowerFlex 750-Series product. The option module receives
its power from the product. When you apply power to the option module 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 6, Troubleshooting.
