Configuring the Adapter Chapter 3
Setting a Fault Action By default, when communications are disrupted (the network cable is
disconnected) and/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:
• Disrupted I/O communication by using parameter
C143 [EN Comm Flt Actn]
.
• An idle controller by using parameter C144 [EN Idle Flt Actn].
Changing the Fault Action
Set the values of parameters C143 [EN Comm Flt Actn] and C144 [EN Idle Flt
Actn]
to the desired responses:
Changes to these parameters take effect immediately. A reset is not required. If
communication is disrupted and then re-established, the drive will automatically
receive commands over the network again.
Setting the Fault Configuration Parameters
When setting parameter C143 [EN Comm Flt Actn] and C144 [EN Idle Flt
Actn]
to 4 “Send Flt Cfg,” the values in the following parameters are sent to the
drive after a communications fault and/or idle fault for drive control fault occurs.
You must set these parameters to values required by your application. Changes to
these parameters take effect immediately. A reset is not required.
ATTENTION: Risk of injury or equipment damage exists. Drive parameters C143
[EN Comm Flt Actn] and C144 [EN Idle Flt Actn] respectively let you determine
the action of the embedded EtherNet/IP adapter and drive if communications
are disrupted or the controller is idle. By default, these parameters fault the
drive. You may configure these parameters so that the drive continues to run,
however, precautions should be taken to ensure 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 (a disconnected network cable or controller in idle state).
Value Action Description
0 Fault The drive is faulted and stopped (Default).
1 Stop The drive is stopped as per P045 [Stop Mode] setting.
2 Zero Data The Reference and Datalink values transmitted to the drive will be set to “0”.
3 Hold Last The Reference and Datalink values transmitted to the drive will be held at their last value.
4 Send Flt Cfg The Logic, Reference, and Datalink values will be transmitted to the drive as configured in
C145 [EN Flt Cfg Logic], C146 [EN Flt Cfg Ref], and C147 [EN Flt Cfg DL 1] through C150 [EN Flt
Cfg DL 4].
Parameter Description
C145 [EN Flt Cfg Logic] A 16-bit integer value sent to the drive for Logic Command.
C146 [EN Flt Cfg Ref] A 16-bit integer value sent to the drive for Reference.
C147 [EN Flt Cfg DL 1] through
C150 [EN Flt Cfg DL 4] A 16-bit integer value sent to the drive for a Datalink.
