Notes/comments:
If the limit in the feedback
monitor is exceeded, Warning
90 will be issued. The SLC
monitors Warning 90 and in the
case that Warning 90 becomes
TRUE then 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 then the frequency
converter continues and the
warning disappears. But Relay 1
will still be triggered until
[Reset] on the LCP.
