(3) Status alarms
Alarm
characters
and
the
frequency setting
may
be
alternately displayed
on
the
LED
in
standard
monitor
mode.
The
following
four
types of characters
may
be
displayed.
C ···When current exceeding
the
overcurrent
stall
level flows.
P ···When voltage exceeding the overvoltage
stall
level
is generated.
L ···When
50%
or
more
of
the
overload trip
value
is
reached.
H ···When
the
temperature
reaches
the overheat protection
alarm
setting
level.
Several alarms
may
also
be
displayed simultaneously.("

Trip information
The
standard monitor
mode
trip display
will
be
entered immediately
when
a trip occurs.
