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 sec. then the drive
continues and the warning
disappears. But Relay 1 will still
be triggered until [Reset] on the
LCP.
