PRDR:
Deceleration
rate
setting
register
(16-bit)
Normally,
specify
the
deceleration
characteristics
for
high
speed
operations
(acceleration/deceleration
operations)
in
the
range
of
1
to
65,535
(0FFFFh).
Even
if
the
ramping-down
point
is
set
to
automatic
(MSDP
=
0
in
the
PRMD
register),
the
value
placed
in
the
RDR
register
will
be
used
as
the
deceleration
rate.
However,
when
PRDR
=
0,
the
deceleration
rate
will
be
the
value
placed
in
the
PRUR.
When
the
ramping-down
point
is
set
to
automatic,
there
are
the
following
restrictions.
While

and
when

operation
(MIPF

is
selected,
make
the
deceleration
time
=
the
acceleration
time.
For
other
operations,
arrange
(deceleration

If
setting
otherwise,
the
axis
may
not
decrease
the
speed
to
the
specified
FL
speed
when
stopping.
In
this
case,
use
a
manual
ramping-down
point
(MSDP
=
1
in
the
RMD
register).
