Features The features of the Option Module include:
•Captive screws to secure and ground the module to the drive.
•Switches to set a node address and network data rate before applying
power to the drive. Alternately, you can disable the switches and use
Option Module parameters to configure these functions.
•Compatibility with various configuration tools to configure the
Option Module and host drive. The tools include the enhanced
PowerFlex 7-Class HIM (Human Interface Module) on the drive,
and drive-configuration software such as DriveExplorer (version
6.01 or higher) or DriveExecutive (version 5.01 or higher).
•Status indicators that report the status of the Option Module and
network communications. They are visible when the drive cover is
removed.
•Parameter-configurable 32-bit Datalinks in the I/O to meet
application requirements (16 for writing data from the network, and
16 for reading data to the network).
•Explicit Messaging and UCMM (Unconnected Message Manager)
support.
•Multiple data exchange methods, including Polled, Cyclic, and
Change of State (COS), to transmit data between the network and
Option Module.
•Master-Slave hierarchy that can be set up so that the Option Module
and PowerFlex 750-Series drive transmit data to and from a scanner
on the network.
•User-defined fault actions to determine how the Option Module and
connected drive respond to:
–I/O messaging communication disruptions (Comm Flt Action)
–Controllers in idle mode (Idle Flt Action)
–Explicit messaging disruptions for drive control via PCCC and
the CIP Register Object (Msg Flt Action)
•Faulted node recovery support. You can configure a device even
when it is faulted on the network if you have a configuration tool that
uses faulted node recovery and have set the Data Rate switch to
position “3.” With this configuration, the Option Module uses
parameter settings stored in EEPROM for the data rate and node
address instead of switch settings.
•Support for DPI routing, enabling access to any networked
PowerFlex 7-Class drive using DriveExplorer (version 6.01 or
higher) to monitor and configure that drive and its connected
peripherals.

Understanding Parameter
Types
The Option Module has two types of parameters:
•Device parameters are used to configure the Option Module to operate
on the network. Device parameters, when viewed using DriveExplorer
or DriveExecutive, appear below the 20-750-DNET listing in the
treeview in a separate Device Parameters folder . When viewed using
the HIM, these parameters appear in the DEV PARAM folder.
•Host parameters are used to configure the Option Module Datalink
transfer and various fault actions with the drive. Host parameters,
when viewed using DriveExplorer or DriveExecutive, appear below
the 20-750-DNET listing in the treeview in a separate Host
Parameters folder. When viewed using the HIM, these parameters
appear in the HOST PARAM folder.

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 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 an Option Module. Failure to
comply may result in injury and/or equipment damage.
!ATTENTION: Risk of equipment damage exists. The
Option Module contains ESD (Electrostatic Discharge)
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, refer to 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], 34 - [Idle Flt
Action], and 36 - [Msg 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 explicit
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. Precautions should be taken to
ensure 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

Setting the Node Address
Switches
Set the Option Module Node Address switches (bottom two switches –
see Figure 2.1) by rotating the switches to the desired value for each
digit.
Important:Each node on the DeviceNet network must have a unique
address. Set the node address before power is applied
because the Option Module 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 Option Module, or disconnect and
reconnect the DeviceNet network cable.
Figure 2.1 Setting Option Module Node Address Switches
The switch settings can be verified by viewing Diagnostic Device Item
number 54 (page 7-6) using an enhanced PowerFlex 7-Class HIM,
DriveExplorer software, or DriveExecutive software.
Setting Description
0 - 63 Node address used by the Option Module if switches are enabled. The default
switch setting is 63. Node address 63 is also the default address used by all
uncommissioned devices. We recommend that you do not use this address as the
final Option Module address.
Important: If the Data Rate switch is set to position “3,” the Option Module uses the
Device Parameter 07 - [Net Addr Cfg] setting for the node address. The default
parameter setting is 63. Refer to Setting the Node Address on page 3-2.
64 - 99 Do not use. The Option Module will not recognize these addresses.
