Chapter 3 Configuring the Option Module
Setting a Fault Action
(Adapter mode only) By default, when communication is disrupted (for example, the network cable is
disconnected), the controller is idle (in program mode or faulted), and/or peer I/O
or explicit messaging for drive control is disrupted, the drive responds by faulting if
it is using I/O from the network. You can configure a different response to these
events:
• Disrupted I/O communication by using Host Parameter 33 - [Comm Flt
Action] .
• An idle controller by using Host Parameter 34 - [Idle Flt Action].
• Disrupted peer I/O by using Host Parameter 35 - [Peer Flt Action].
• Disrupted explicit messaging for drive control via PCCC, the CIP
Register Object or the CIP Assembly object by using
Host Parameter 36 -
[Msg Flt Action] .
Changing the Fault Action
Set the values of Host Parameters 33 - [Comm Flt Action], 34 - [Idle Flt Action],
35 - [Peer Flt Action] , and 36 - [Msg Flt Action] to any of these responses.

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 -
[Comm Flt Action], 34 - [Idle Flt Action], 35 - [Peer Flt Action], and 36 -
[Msg Flt Action] respectively let you determine the action of the option module
and connected drive if communication is disrupted, the controller is idle, peer I/O
is disrupted, or explicit messaging for drive control is disrupted. By default, these
parameters fault the drive. You may configure 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 network cable, controller in idle state or
explicit message control disruption).
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. 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 (Host
Parameters 37 - [Flt Cfg Logic], 38 - [Flt Cfg Ref], and 39 - [Flt Cfg DL 01] through
54 - [Flt Cfg DL 16]).
