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