Two drive monitor parameters, U6-98 and U6-99, assist the user 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 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.
