Notes/comments:
If the limit in the feedback monitor is exceeded,
warning 90,
Feedback monitor
is issued. The SLC monitors the warning and in
the case that it becomes true, 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 drive
system continues and the warning disappears. However, relay 1
is still triggered until [Reset] is pressed on the LCP.
