Positioning
operations
using
a
pulsar
input
(MOD:
51h)
The
PCL
positioning
is
synchronized
with
the
pulsar
input
by
using
the
PRMV
setting
as
incremental
position
data.
This
mode
allows
positioning
using
a
pulsar
input.
The
feed
direction
is
determined
by
the
sign
in
the
PMV
register.
When
PA/PB
signals
are
input,
the
LSI
outputs
pulses
and
the
positioning
counter
counts
down.
When
the
value
in
the
positioning
counter
reaches
zero,
movement
on
the
axis
will
stop
and
another
PA/
PB
input
will
be
ignored.
Set
the
RMV
register
value
to
zero
and
start
the
positioning
operation.
The
LSI
will
stop
movement
on
the
axis
immediately,
without
outputting
any
command
pulses.

to
OUNT R1)
(MOD:
2h)
The
PCL
positioning
is
synchronized
with
the
pulsar
input
by
using
the
PRMV
setting
as
the
absolute
value
for
COUNTER1.
The
direction
of
movement
is
determined
by
the
relationship
between
the
value
in
PRMV
and
the
value
in
COUNTER1.
When
starting,
the
difference
between
the
values
in
RMV
and
COUNTER1
is
loaded
into
the
positioning
counter.
When
a
PA/PB
signal
is
input,
the
PCL
outputs
pulses
and
decrements
the
positioning
counter.
When
the
value
in
the
positioning
counter
reaches
"0,"
the
PCL
any
further
ignores
PA/PB
input.
If
you
try
to
start
with
PRMV
=
COUNTER1,
the
PCL
will
not
output
any
pulses
and
it
will
stop
immediately.

that
this

uses

instead
of
