Caution
The emergency stop command forcibly stop the motor with the inverter unit key operation
even
if
the
command
mode
is
not set
to
panel operation
mode.
This command cannot
be
prohibited with
the
command
mode
selection.
When
executed, the emergency stop will
be
regarded
as
a trip
and
will
be
recorded
as
a past fault.
7.4.7 Fault Reset
Remove
the
trip cause before resetting
an
inverter that
has
tripped due to a failure
or
other fault.
The
inverter will trip again if the cause
is
not removed.
Reset the tripped state with
one
of
the
following methods:
Reset
(1)
Turn off the power (until the
LED
display goes out) Note

or
with
the
panel
during
the
required cooling time.
