input.
(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 coordinate
system
shift quantity.

For the
angle
of
rotation,
work

external
data
input
must
be corrected.
