During
acceleration
of
inverter,
the
actual
motor
speed
rise
rate
may
lower
than
the
output
frequency
rise
rate
because
of
too
big
load.
If
no
measures
to
take,
inverter
will
trip
caused
by
over-current.
The
principle
of
over-current
protection
is
to
detect
the
output
current
of
inverter
during
inverter
operation
and
compare
it
with
over-current
stall
threshold
determined
by
PA.12.
If
it
exceeds
the
value
of
PA.12
during
acceleration,
inverter
will
remain
output
frequency;
if
it
exceeds
the
value
of
PA.12
during
constant
speed
running,
inverter
will
decrease
output
frequency.
W
hen
output
current
of
inverter
is
lower
than
the
value
of
PA.12,
inverter
will
continue
to
accelerate
until
output
frequency
reach
frequency
reference.
Please
refer
to
following
diagram.
