The
maximum
output

of
this
IC
can
be
attained
when
the
reference
clock
is
30
MHz,
PRMG
=
1,
and
PRFH
=
16383.
In
these
conditions,
the
multiplication
rate
is
915.527x
and
the
IC
will
output
14.999
Mpps.
♦
PRDP:
Ramping-down
point
register
(24-bits)
Specify
the
value
used
to
determine
the
deceleration
start
point
for
positioning
operations
that
include
acceleration
and
deceleration.
The
meaning
of
the
value
specified
in
the
RDP
changes
with
the
"ramping-down
point
setting
method",
(MSDP)
in
the
PRMD
register.
<When
set
to
manual
(MSDP=1
in
the
PRMD
register)>
Set
the
number
of
pulses
at
which
to
start
deceleration,
in
the
range
of
0
to16,777,215
(0FFFFFFh).
When
the
(PRDP
set
value)
(Number
of
residual
pulses),
the
PCL
will
start
decelerating.
Note:
In
order
to
obtain
the
correct
manual
setting
value,
you
have
to
know
the
actual
maximum
speed.
When
there
is
only
a
small
feed
amount
and
the
motor
would
have
to
decelerate
while
still
accelerating,
or
if
the
maximum
speed
is
automatically
modified
by
the
FH
correction
function,
the
PCL
cannot
calculate
the
manual
setting
value.
Therefore,
in
this
case
turn
OFF
the
FH
correction
function
before
trying
the
operation.
Alternatively,
you
can
calculate
the
manual
FH
correction
and
then
obtain
the
corrected
maximum
speed
using
the
following
equations.
The
optimum
value
of
the
ramping
down
position
can
be
as
follows.
1)
Linear
deceleration
(MSMD=0
of
the
PRMD
register)
(PRFH

-
PRFL

)
x
(PRDR

2)

without
a
linear
range
(MSMD=1
in
the
PRMD
register
and
the

(PRFH

)
x
(PRDR

3)

with
a
linear
range
(MSMD=1
in
the
PRMD
register
and
the
PRDS
register
>0)
(PRFH

PRFL)
x
(PRFH

x
(PRDR

Optimum

[Number

(PRMG

x
16384
Start
deceleration
at
the
point
when
the
(positioning
counter
value)
(RDP
set
value).
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.
