Notes/comments:
If the limit in the feedback
monitor is exceeded, Warning
90 is issued. The SLC monitors
Warning 90 and if Warning 90
becomes TRUE, Relay 1 is
triggered.
External equipment may then
indicate that service may be
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] on
the LCP.
