Rockwell Automation RECOMM-DNET DeviceNet Adapter for use with DPI AC Drives - Manual (Page 41)

Configuring the DeviceNet Adapter 4-17
4.9 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 Comm Flt Action (10) and a different response to
an idle scanner using Idle Flt Action (11).
4.9.1 Changing the Fault Action
Set the values of Comm Flt Action (10) and Idle Flt Action (11) to
the desired responses as shown in table 4.6. See figure 4.26 for
sample LCD OIM Fault Action Screens.
!
ATTENTION: Comm Flt Action (10) and Idle Flt
Action (11) let you determine the action of the
adapter and connected drive if communications are
disrupted or the scanner 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 hazard
of injury or equipment damage. Failure to observe
these precautions could result in bodily injury or
damage to, or destruction of, equipment.
Table 4.6 – Selections for Drive Response to Communication Fault
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 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 Flt Cfg Logic (15)
through Flt Cfg D2 In (24).
