Configuring the Adapter Chapter 3
Setting a Fault Action By default, when communications are disrupted (the network cable is
disconnected) and/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:
• Disrupted I/O communication by using
Device parameter
15 [Comm Flt Actn] .
• An idle scanner by using
Device parameter 16 [Idle Flt Actn].
Changing the Fault Action
Set the values of Device parameters 15 [Comm Flt Actn] and 16 [Idle Flt Actn]
to the desired responses:
Changes to these parameters take effect immediately. A reset is not required.
If Multi-Drive mode is used, the same fault action is used by the adapter for all of
the drives it controls (Drive 0...4).
Setting the Fault Configuration Parameters
When setting
Device parameters 15 [Comm Flt Actn] and 16 [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. Device parameters
15 [Comm Flt Actn] and 16 [Idle Flt Actn] respectively let you determine the
action of the 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 a controller in idle state).
Value Action Description
0 Fault The drive is faulted and stopped. Datalink data is no longer sent to the drive. (Default)
1 Stop The drive is stopped as per Host parameter P045 [Stop Mode] setting. Datalink data sent to
the drive remains unchanged.
2 Zero Data The drive is sent “0” values for all Reference and Datalink 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 Reference and Datalink data that you set in the fault configuration
parameters (Device parameters 17 [Flt Cfg Logic], 18 [Flt Cfg Ref], and 19 [Flt Cfg DL 1]
through 22 [Flt Cfg DL 4]).
Device Parameter Description
17 [Flt Cfg Logic] A 16-bit integer value sent to the drive for Logic Command.
18 [Flt Cfg Ref] A 16-bit integer value sent to the drive for Reference.
19 [Flt Cfg DL 1] through
22 [Flt Cfg DL 4] A 16-bit integer value sent to the drive for a Datalink.
