Rockwell Automation 22-COMM-P PowerFlex Profibus Adapter - Manual (Page 33)

Configuring the Adapter 3-5
By default, when Profibus communication is 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 disruption using Parameter 9 - [Comm Flt
Action] and a different response to an idle scanner using Parameter 10 -
[Idle Flt Action].
Changing the Fault Action
Set the values of Parameters 9 - [Comm Flt Action] and 10 - [Idle Flt
Action] to the desired responses:

ATTENTION: Risk of injury or equipment damage exists.
Parameters 9 - [Comm Flt Action] and 10 - [Idle Flt Action] let you
determine the action of the adapter and connected drive if
communications are disrupted or the controller is idle. By default, these
parameters fault the drive. You can set these parameters so that the drive
continues to run. Precautions should be taken to ensure that the settings
of these parameters do not create a risk of injury or equipment damage.
Value Action Description
0 Fault (Default) The drive is faulted and stopped, the last state of bits 0…3 in the
Logic Command word is held, and the rest of the bits are
cleared. (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 (Parameters 13 - [Flt Cfg Logic] and 14- [Flt Cfg
Ref]).
5 (1)
(1) This setting is available only with adapter firmware revision 3.xxx or later.
Fault&ClrCmd The drive is faulted and stopped, and all of the bits (including
bits 0…3) in the Logic Command word are cleared.
