Start

value)
≤

<When
set

(MSDP
=

PRMD
register)>
This
is
an
offset
value
for
the
automatically
set
ramping-down
point.
Set
in
the
range
of
-8,388,608
(800000h)
to
8,388,607(7FFFFFFh).
When
the
offset
value
is
a
positive
number,
the
axis
will
start
deceleration
at
an
earlier
stage
and
will
feed
at
the
FL
speed
after
decelerating.
When
a
negative
number
is
entered,
the
deceleration
start
timing
will
be
delayed.
If
the
offset
is
not
required,
set
to
zero.
When
the
value
for
the
ramping-down
point
is
smaller
than
the
optimum
value,
the
speed
when
stopping
will
be
faster
than
the
FL
speed.
On
the
other
hand,
if
it
is
larger
than
the
optimum
value,
the
axis
will
feed
at
FL
low
speed
after
decelerating.
