General Drive Errors
These errors usually result from a miscommunication between the drive
processors or involve a mechanical malfunction. In most cases, these types of
errors report an error message and an FSC to the control panel. The only
exceptions are power supply problems and display malfunctions. The FSC can
be used to determine a recovery procedure.
Pressing the
Enter
button can clear some error messages; cycling the power to
the MiniLibrary system can clear others. Often the MiniLibrary system will
resume normal operation. Other errors are repeated when the operation is
attempted again. Such recurrent errors might require more extensive recovery
procedures, such as replacement of a part.
To help you in localizing persistent errors, there are Customer Engineer (CE)
diagnostics available in the Maintenance submenu and a User diagnostics
available on the Demo submenu. The diagnostics are described at the end of
this chapter.
Error Recovery
Figure 6-1 shows the recommended steps for error recovery. This chart should
be followed in all cases.
ERPs are listed in Table 6-1. FSCs are listed in Table 6-2 through 6-10.
