(I)
The
work
coordinate
system
shift
quantity
can
be
corrected
by
external
data
input
signal.
Upon input
of
an
external
correction
quantity,
all
shift
quantities
of
G54
(Jl)
to
G5y(J27)are
changed
to
new
shift
quantities
by
adding
the
external
correction
quantity.
In
this
case,
the external
work
coordinate
system
correction
quantity
is
corrected,
without
directly
correcting
the work

shift
quantity.
