Setting A Fault Action - Allen-Bradley PowerFlex 20-comm-c FRN 1. Series User Manual

3-6 Configuring the Adapter

Setting a Fault Action

By default, when communications are disrupted (for example, a cable is
disconnected) or the master is idle, 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 10 - [Comm Flt Action]
and a different response to an idle scanner using Parameter 11 - [Idle
Flt Action].
ATTENTION: Risk of injury or equivalent damage exists.
Parameter 10 - [Comm Flt Action] and Parameter 11 - [Idle Flt
!
Action] lets you determine the action of the adapter and connected Host
product if the controller is idle (e.g. in program mode). This parameter
can be used to fault (default setting) the Host product or perform
another function such as allow the Host to continue to run. Some
ControlNet scanners may operate differently when a controller is idle
which could limit the Idle Fault Action's operating states. The Idle Flt
Action should be verified when commissioning the drive on the
network by testing the operation with the controller in idle.
To change the fault action
• Set the values of Parameters 10 and 11 to the desired responses:

Description
The drive is faulted and stopped. (Default)
The drive is stopped, but not faulted.
The drive is sent 0 for output data. This does not
command a stop.
The drive continues in its present state.
The drive is sent the data that you set in the fault
configuration parameters (Parameters 15 - [Flt Cfg
Logic] through 24 - [Flt Cfg D2 In]).
