Rockwell Automation 22-SCM-232 Serial Converter Module - Manual (Page 26)

3-8 Configuring the Serial Converter Module
By default, when DF1 serial communications are disrupted (for example,
a serial cable is disconnected) and control I/O is being transmitted, the
serial converter module and connected drive respond by faulting. You
can set a different response to communication disruptions using
Parameter 04 - [Comm Flt Action].
To change the fault action
• Set the value of Parameter 04 - [Comm Flt Action] to the desired
response:
Figure 3.9 Comm Flt Action Parameter in HyperTerminal
Changes to this parameter take effect immediately. A reset is not
required.
Setting the Fault Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameter 04 - [Comm Flt Action] lets you determine the action of
the serial converter module and connected drive if communications are
disrupted. By default, this parameter faults the drive. You can set this
parameter so that the drive continues to run. Precautions should be
taken to ensure that the setting of this parameter does not create a
hazard of injury or equipment damage.
Action Description
Fault The drive is faulted and stopped. (Default)
Stop The drive is stopped, but not faulted (DSI host products only).
Zero data The drive is sent 0 for output data after a communications disruption.
This does not command a stop.
Hold last The drive continues in its present state after a communications
disruption.
