Notes/comments:
Exceeding the limit in the feedback monitor issues warning
90, Feedback monitor . The SLC monitors warning 90,
Feedback monitor , and if the warning becomes true, relay 1
is triggered.
External equipment indicates if service is required. If the
feedback error goes below the limit again within 5 s, the
frequency converter continues, and the warning
disappears. But relay 1 is still triggered until [Reset] is
pressed on the LCP.
