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
require service. If the feedback
error goes below the limit
again within 5 s, then the
frequency converter continues
and the warning disappears.
Press [Reset] on the LCP to
reset Relay 1.
