Two drive monitor parameters, U6-98 and U6-99 assist in network troubleshooting:
• U6-98 displays the first declared fault since the last power cycle. U6-98 is only cleared
upon drive power-up.
• U6-99 displays the present option SI-EP3 status. U6-99 is cleared upon a network-issued
fault reset and upon power-up.
If another fault occurs while the original fault is still active, parameter U6-98 retains the
original fault value and U6-99 stores the new fault status value.
