Precautions
• If
the
motor
capacity
is
small
compared
to
the
Inverter
capacity,
or
if
the
motor
is
operated
using
the
fac-
tory
settings,
resulting
in
the
motor
stalling,
lower
the
set
value
of
L3-02.
• If
using
the
motor
in
the
constant
output
range,
L3-02
will
be
automatically
lowered
to
prevent
stalling.
L3-03
is
the
limit
value
to
prevent
the
stall
prevention
level
in
the
constant
output
range
from
being
reduced
more
than
necessary.
• Set
the
parameters
as
a
percent
taking
the
inverter
rated
voltage
to
be
100%.
