[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).
WARNING: 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.

Preparing for an Installation Before installing the option module, do the following:
• Read the PROFIBUS Installation Guideline for details on PROFIBUS
networks.
• Verify that you have all required equipment.
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.
Setting the Endianness and Node Address Switches
Set the Endianness of the option module with Byte Swap switch 8 (see
Figure 1
closed ‘1’ (big-endian) data formats for the cyclic data exchanged on the
network. The cyclic data consists of the following items:
). The Byte Swap switch can be set to either open ‘0’ (little-endian) or
• CTRL: Logic Command Word (4 bytes)
• REF: Speed Reference (4 bytes)
• STAT: Logic Status Word (4 bytes)
• FEEDBACK: Speed Feedback (4 bytes)
• 0…16 Datalinks (4 bytes each)
Depending on the setting of the Byte Swap switch 8, the 4 bytes for each of the
preceding data items are swapped.

Figure 1 - Setting Option Module Node Address Switches
IMPORTANT
Each node on the PROFIBUS network must have a unique address. Set
the node address before power is applied because the option module
detects the node address during initialization (Power On Reset). To
change a node address, you must set the new value and then remove
and reapply power to (or reset) the option module.
Set the Node Address by setting Node Address switches 1...7 to their binary
equivalent, where '0' and '1' indicate switch positions 'Open' and 'Closed'
respectively. Table 1
switch settings required to set that respective address.
lists node addresses and the corresponding Node Address

Chapter 2 Installing the Option Module
Descriptions of node address values are as follows.
Node Address Value Description
00
01…125 Node address used by the option module.
126 The default address setting.
If the Node Address value is set to ‘00’, the option module uses Device Parameter
05 [Net Addr Cfg] to set the Node Address. See Setting the Node Address on
page 30.
The switch settings can be verified by viewing Device Parameter 06 [Net Addr
Act], a read-only parameter, with any of the following drive configuration
tools:
• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM
• Connected Components Workbench software
IMPORTANT
Remove power from the product before installing the option module in
the control pod.
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 PowerFlex 750-Series product, 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-PBUS option
module—and the lower mounting screw of that module is a larger T15
Torx head screw, perform addition steps 2a through 2d. 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 option module is shipped with a small bag containing a spare T8
Torx head mounting screw and an adhesive-backed polycarbonate
insulator strip. The larger T15 Torx head mounting screw on the adjacent
left module may electrically contact the metal PROFIBUS cable connector
when attached to the PROFIBUS module. The polycarbonate insulator
strip is provided to help prevent electrical contact between the smaller T8
Torx head mounting screw and the PROFIBUS cable metal connector
when attached to the PROFIBUS module. Either of these possible
electrical contact situations may cause faulty operation. To help 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.
To remove the captive T15 Torx head screw, the module must
be removed to back the screw out of the mounting clip.
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 drive. Torque the screw to
0.45…0.67 N•m (4.0…6.0 lb•in).
d. Attach the adhesive-backed polycarbonate strip to the metal
PROFIBUS cable connector in a location that prevents electrical
contact between the connector and the adjacent module’s lower
mounting screw when the connector is attached to the PROFIBUS
module.

Chapter 2 Installing the Option Module
Connecting the Option Module to the Network
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 connecting the option
module to the network.
1. Remove power from the PowerFlex 750-Series product.
2. Remove the product cover and lift up the drive HIM bezel to its open
position to access the drive control pod.
3. Use static control precautions.
4. Route the PROFIBUS cable through the bottom of the PowerFlex drive.
5. Connect a PROFIBUS connector to the cable.
PROFIBUS 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. Phoenix SUBCON-PLUS-PROFIB/AX/SC
(Part # 2744380), Siemens 6GK1500-0FC00, or Brad BM5G60PP4Mxxx
are recommended for use with PowerFlex 750-Series drives.
Figure 2 - PROFIBUS Connector
6. Connect the PROFIBUS cable to the option module and secure it with the
two screws on the connector.
IMPORTANT
PROFIBUS communication may not operate correctly if the
cable shield does not make full contact with the connector
housing.
