Selection
of
Power
of
Braking
Resistor
In theory
,
the power of the braking resistor is consistent with the braking power
.
But in
consideration
that
the
de
-
rating
is
70
%,
you
can
calculate
the
power
of
the
braking
resistor
according
to
the
formula
0
.

x
Pr
=
Pb
x
D
.
•
Pr
refers
to
the
power
of
resistor
.
•
D
refers
to
the
braking
frequency
(
percentage
of
the
regenerative
process
to
the
whole
working
process
)

Table

below
provides
data
for
reference
.
You
can
select
different
resistance
and
power
based
on
actual
needs
.
However
,
the
resistance
must
not
be
lower
than
the
recommended
value
.
The
power
may
be
higher
than
the
recommended
value
.
The
braking
resistor
model
is
dependent
on
the
generation
power
of
the
motor
in
the
actual
system and is also related to the system inertia
,
deceleration time and potential energy
load
.
For systems with high inertia
,
and
/
or rapid deceleration times
,
or frequent braking
sequences
,
the braking resistor with higher power and lower resistance value should be
selected
.
