Fault Code and Time Stamp
The fault code with descriptive text for each entry can be viewed with a HIM.
Once the fault code is displayed, pressing the enter key again on the HIM
displays the time stamp associated with that fault code. The time stamp is the
elapsed time since the fault occurred.
When using one of the available software tools (DriveExecutive, DriveExplorer,
Connected Component Workbench, or Logix Designer), the fault code,
descriptive text, and time stamp are displayed simultaneously.
Resetting or Clearing a Fault
A latched fault condition can be cleared by the following methods.
• An off to on transition on a digital input configured as DI Clear Fault.
• Pressing the “CLR” soft key or Stop button on the HIM once a fault has
been displayed.
• A DPI peripheral (several ways).
• Performing a reset to factory defaults via parameter write.
• Cycling power to the drive such that the control board goes through a
power-up sequence.
Resetting faults clears the faulted status indication. If any fault condition still
exists, the fault is re-latched and another entry made in the fault queue.
Clearing the Fault Queue
Performing a fault reset does not clear the fault queue. This can be done from a
menu selection of the HIM or from a DPI command through the
communications port.
