Notes/comments:
If the limit in the feedback
monitor is exceeded, warning
61 feedback monitor is issued.
The SLC monitors warning 61
feedback monitor. If warning 61
feedback monitor becomes true,
relay 1 is triggered.
External equipment could
indicate that service is required.
If the feedback error goes
below the limit again within 5
s, the adjustable frequency
drive continues and the
warning disappears. But relay 1
persists until [Off/Reset] is
pressed.
