When
circular
interpolation
is
selected
with
S-curve
acceleration/deceleration,
the
PRUS
and
PRDS
register
values
cannot
be
set
to
zero
(auto).
To
control
the
ramp
down
point
while
using
linear
interpolation1,
the
PCL
executes
a
comparison
of
RPLS
and
RSDC
for
the
longest
axis.
The
RSDC
setting
for
any
shorter
axes
will
be
invalid.
However,
if
more
than
one
axis
has
the
same
length
and
they
are
the
longest
axes,
to
specify
a
ramp
down
point
manually
you
must
enter
the
same
value
for
all
of
the
interpolated
axes.
To
control
the
ramp
down
point
while
using
circular
interpolation,
the
PCL
executes
a
comparison
of
CIC
and
RSDC
on
the
control
axis.
Therefore,
to
specify
a
ramp
down
point
manually,
write
to
RSD
on
the
control
axis.
Error
stop
If
any
of
the
axes
stops
with
an
error,
all
of
the
axes
being
interpolated
will
stop
(SERR
=
1).
By
reading
the
REST
(error
stop
cause)
register,
you
can
determine
which
axis
actually
stopped
with
an
error.
SD
input
When
SD
input
is
enabled
(MSDE
(bit
8)
in
the
RMD
register
is
set
to
1),
and
if
the
SD
input
turns
ON
either
of
the
axes,
both
axes
will
decelerate
or
decelerate
and
stop.
Idling
control
If
any
axis
is
in
idling
range,
none
of
the
axes
being
interpolated
will
accelerate.
Correction
function
When
phases
are
changed
during
circular
interpolation,
backlash
correction
and
slip
correction
control
cannot
be
used.
Continuous
interpolation
The
PCL
can
use
the
pre-register
to
make
a
continuous
linear
interpolation
or
circular
interpolation.
However,
when
the
axes
being
interpolated
change
during
a
continuous
interpolation,
requires
special
care.
An
example
of
the
settings
for
continuous
interpolation
using
the
pre-register
is
shown
in
section
11-
14-1,
"Start
triggered
by
a
stop
on
another
axis."
