Rockwell Automation RECOMM-485 RS485 DFI Communications Module - Manual (Page 27)

Configuring the RS485 DF1 Module 4-5
4.7 Setting a Fault Action
By default, when communications are disrupted (for example, a
cable is disconnected) or the scanner 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 module parameter 10 (Comm Flt Action).
Set the value of module parameter 10 (Comm Flt Action) to the
desired response as shown in table 4.2. See figure 4.6 for a sample
LCD OIM Fault Action screen.
Changes to this parameter take effect immediately. A reset is not
required.
!
ATTENTION: Module parameter 10 (Comm Flt
Action) lets you determine the action of the module
and connected drive if communications are
disrupted. By default, this parameter faults the drive.
You can set the 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.
Table 4.2 – Selections for Drive Response to Communication Fault
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.
4 Send Flt Cfg The drive is sent the data that you
set in the fault configuration
parameters 14 through 23 (Flt Cfg
Logic through Flt Cfg D2 In).
