description
The
same
operation
method
of
reference
point
return
is
employed
as
the
.conventional
-method.
.
.
By
using
the
concept
of
imaginary
phase-C.
this
function
can
change
the
relation between
the
zero-point
LS
signal
and
phase-C
pulse
positions
or
the
relation between
the
zero-point
LS
signal
arid
reference
point
positions
only
by rewriting
the
parameters
instead
of
adjustment
of
zero-point
LS
signal
position.
Additionally,
by
adjusting
the
final
traveling
distance.
the
distance
from
the
zero-point
LS
signal
to
the
reference
point
can
be
kept
constant.
That
is;
it
is
possible
to
set
the
reference
point
position
at
an
arbitrary
constant
distance
from
the
zero-point
LS
signal,
disregarding
the
phase-C
pulse
position.
