P2

is
used
to
scale
the
analog
input
prior
to
being
applied
as
a
reference
to
the
drive.
For
example,
if
P2
‐

is
set
for
0
–
10V,
and
the
scaling
factor
is
set
to
200.0%,
a
5

input
will
result
in
the
drive
running
at
maximum
speed

P2

defines
an
offset
for
the
analog
input,
as
a
percentage
of
the
full
range
of
the
input.
A
positive
offset
is
deducted
from
the
incoming
analog
signal
and
a
negative
offset
is
added
to
the
signal.
For
example,
if
P2
‐
33
is
set
for
0
–
10V,
and
the
analog
offset
is
set
to
10.0%,
then
1
volt
(10%
of
10V)
will
be
deducted
from
the
incoming
analog
reference
prior
to
it
being
applied.
