Setting a Fault Action
By default, when I/O communication is disrupted (for example, a cable is
disconnected) or the controller is idle (in program mode or faulted), the
drive responds by faulting if it is using I/O from the network. You can
configure a different response to these faults:
• Disrupted I/O communication by using Parameter 10 - [Comm Flt
Action]
• An idle controller by using Parameter 11 - [Idle Flt Action]
Changing the Fault Action
Set the values of Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt
Action] to an action that meets your application requirements.
Changes to these parameters take effect immediately. A reset is not
required.
If communication is disrupted and then is re-established, the drive will
automatically take commands from the network again.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
I/O communication is 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, 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 cable
or faulted controller).
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’ values for 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 14 - [Flt Cfg Logic] through 23 - [Flt Cfg D2 In]).
