If the power dip ride
-
through function is enabled
,
when the bus voltage is lower than the
value
of PB
-
12
,
the
AC
drive
reduces the
running
frequency
based
on the
power dip
ride
-
through frequency decline rate set in PB
-
10
.
When the bus voltage rises to the value of
PB
-
12 and remains such state for the
time
set in PB
-
11
,
the
AC drive restores to the set
frequency
.
If the bus voltage does not rise to the value of PB
-
12
,
the AC drive keeps reducing the
running
frequency
to
0
and
then
stops
.
If PB
-
10 is set to a small value
,
the load feedback energy is small and the low
-
voltage
compensation
is
not
effective
.
If
PB
-
10
is
set
to
a
very
large
value
,
the
load
feedback
energy
is
large
,
which
may
cause
overvoltage
protection
.
Set
this
parameter
properly
based
on
the
inertia
and
load
.
