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. Read and understand this entire manual
before proceeding. Failure to comply may result in injury and/or
equipment damage.
ATTENTION: Risk of equipment damage exists. The adapter
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 adapter. 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
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.

Publication 20COMM-UM009D-EN-P
1-4 Getting Started
ATTENTION: Risk of injury or equipment damage exists.
Parameter 15 - [Comm Flt Action] lets you determine the
!
action of the adapter and connected drive if communications are
disrupted. By default, this parameter faults the drive. You can set
this parameter so that the drive continues to run. Precautions
should be taken to ensure that the setting of this parameter does
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).
ATTENTION: Risk of injury or equipment damage exists.
Parameter 11 - [Network Timeout] lets you determine how
!
long it will take the adapter to detect network communication
losses. By default, this parameter sets the timeout to ten seconds.
It can be set so that the duration is shorter, longer, or disabled.
Take precautions to ensure that the setting does 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).
ATTENTION: Risk of injury or equipment damage exists. DPI
or SCANport host products must not be directly connected via
!
1202 cables. Unpredictable behavior due to timing and other
internal procedures can result if two or more hosts are connected
in this manner.
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, Inc. does not assume
responsibility or liability (to include intellectual property
liability) for actual use of the examples shown in this publication.

3-6 Configuring the Adapter
Setting a Network Time-out
The network timeout sets an interval within which the adapter must
communicate with its master. If this time is exceeded, the adapter
determines a loss of network communications has occurred and responds
with the action specified in Parameter 15 - [Comm Flt Action].
By default, the timeout is set to ten (10) seconds. You can increase or
decrease this value. Alternatively, you can set the value to zero (0) so that
the adapter does not detect communication losses.
ATTENTION: Risk of injury or equipment damage exists.
Parameter 11 - [Network Timeout] lets you determine how
!
long it will take your adapter to detect network communication
losses. By default, this parameter sets the timeout to ten (10)
seconds. You can set it so that the duration is shorter, longer, or
disabled. Take precautions to ensure that the setting does 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).

Setting a Fault Action
By default, when I/O communications are disrupted (for example, a cable is
disconnected), the drive responds by faulting if it is using I/O from the
network. You can configure a different response to disrupted I/O
communication using Parameter 15 - [Comm Flt Action].
ATTENTION: Risk of injury or equipment damage exists.
Parameter 15 - [Comm Flt Action] lets you determine the action
!
of the adapter and connected drive if I/O communications are
disrupted. By default, this parameter faults the drive. You can set
this parameter so that the drive continues to run. Precautions
should be taken to ensure that the setting of this parameter does
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).
Changing the Fault Action
Set the value of Parameter 15 - [Comm Flt Action] to the desired
response:
Value Action Description
0 Fault The drive is faulted and stopped. (Default)
1 Stop The drive is stopped, but not faulted.
2 Zero Data The drive is sent 0 for output data. (The command word and Reference are
set to zero.) This does not command a stop.
3 Hold Last The drive continues in its present state.
4 Send Flt Cfg The drive is sent the data that you set in the fault configuration parameters
(Parameters 18 - [Flt Cfg Logic] through 27 - [Flt Cfg D2 In]).
