Parameters
Notes/Comments:
If the limit in the feedback
monitor is exceeded,
Warning 90 is issued. The
SLC monitors Warning 90
and if 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 sec
then the adjustable
frequency drive continues
and the warning
disappears. Press [Reset] on
the LCP to reset Relay 1.
