Troubleshooting the Drive

Using the OIM

The OIM provides immediate visual notification of alarm or fault conditions as

well as the following diagnostic information:

• Entries in the fault queue

• Fault parameters

• Drive status parameters

• Selected device version and status information

• OIM version information

Accessing the Fault Queue

As described in About the Fault Queue on page 202, the drive automatically

retains a history of the last four faults that have occurred in the fault queue.

To access the fault queue, press the F4 key at the process display screen, or see

Figure 82

to access the fault queue from the Main Menu.
