Rockwell Automation 20-COMM-I Interbus Adapter - Manual (Page 28)

3-6 Configuring the Adapter
By default, when 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 communication
disruptions using Parameter 6 - [Comm Flt Action].
To change the fault action
• Set the values of Parameters to the desired responses:

Changes to the parameter take effect immediately. A reset is not
required.
Setting a Fault Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 6 - [Comm Flt Action] lets you determine the action of
the adapter and connected PowerFlex drive if communications are
disrupted. By default, this parameter faults the PowerFlex drive. You
can set this parameter so that the PowerFlex drive continues to run.
Precautions should be taken to ensure that the setting of this parameter
does not create a hazard of injury or equipment damage.
Value Action Description
0 Fault (default) 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 after a
communications disruption. This does not
command a stop.
3 Hold Last The drive continues in its present state after a
communications disruption.
4 Send Flt Cfg The drive is sent the data that you set in the fault
configuration parameters (Parameters 10 - [Flt Cfg
Logic] through 19- [Flt Cfg D2]).
