4-8 Serial Converter for use with DPI AC Drives
4.4.2 Setting the Fault Action
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 and connected product respond by
faulting. You can set the actions listed in table 4.3.
:
To change the fault action, set the value of Comm Flt Action (04) to
the desired fault action. Refer to figure 4.8.
Changes to this parameter take effect immediately. A reset is not
required.
!
ATTENTION: The setting of Comm Flt Action (04)
determines the action of the serial converter and
connected product if DF1 serial communications are
disrupted. By default, this parameter faults the
product. You can set this parameter so that the
product continues to run. Ensure that the setting of
this parameter does not create a hazard. Failure to
observe this precaution could result bodily injury
and/or damage to equipment.
