3-14 Configuring the Adapter
PowerFlex® 755 Drive Embedded EtherNet/IP Adapter User Manual
Publication 750COM-UM001A-EN-P
Setting a Fault Action
By default, when I/O communications are disrupted (for example, the
network cable is disconnected), the controller is idle (in program mode
or faulted), and/or Peer I/O or explicit messaging for drive control is
disrupted, the drive responds by faulting. You can configure a different
response to:
• Disrupted I/O communication by using Parameter 54 - [Comm Flt
Action].
• An idle controller by using Parameter 55 - [Idle Flt Action].
• Disrupted Peer I/O by using Parameter 56 - [Peer Flt Action].
• Disrupted explicit messaging for drive control via PCCC and the CIP
Register Object by using Parameter 57 - [Msg Flt Action].
Changing the Fault Action
Set the values of Parameters 54 - [Comm Flt Action], 55 - [Idle Flt
Action], 56 - [Peer Flt Action], and 57 - [Msg Flt Action] to the
desired responses:
!
ATTENTION: Risk of injury or equipment damage exists.
Embedded adapter Parameters 54 - [Comm Flt Action], 55
- [Idle Flt Action], 56 - [Peer Flt Action], and 57 - [Msg Flt
Action] respectively let you determine the action of the
adapter and drive if I/O communication is disrupted, the
controller is idle, Peer I/O is disrupted, or explicit messaging
for drive control is disrupted. 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. When commissioning the drive, verify
that your system responds correctly to various situations (for
example, a disconnected network cable, controller in idle
state or explicit message control disruption).
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. 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 58 - [Flt Cfg Logic], 59 - [Flt Cfg Ref], and 60
- [Flt Cfg DL 01] through 75 - [Flt Cfg DL 16]).
