Notes/comments:
If the limit in the feedback
monitor is exceeded, warning
90 Feedback Mon. is issued. The
SLC monitors warning 90 and if
the warning 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 pressing
[Reset] on the LCP.
