Notes on manual skip
function
1. To
move
axes to
the
contact
point, move
a single
axis
at one
time
(simultaneous
1-axis
operation.)
2. The
skip
contact
position data
are
canceled
only by
an external instruction
such
as the manual skip
mode
entry
signal or a
request to reset.
The data
are
retained
unless change is
commanded
externally.
3.
The
manual skip function is
ineffective
for
the 4th and
5th axes.
4.
If the manual skip
entry
signal is input
out
or
the manual
mode,
the
signal is disregarded
and the
manual skip mode
ON
signal
will
not
be
output.
5.
If simultaneous return of all axes
to
home position has
not
been performed after
power
was turned
on
before the
rising of the
touch sensor
signal is
detected in the manual
skip
mode,
the touch sensor
signal
is
disregarded and
no
measurement
will be made.
6.
Axes do
not
move
in the direction of the
contact
with the touch
sensor.
7. After
contacting
the
touch
sensor,
the tool
cannot
be moved in the direction of
contact
with the
touch sensor without a certain
length
(determined
by
Pm6847)
of
retraction.
Retraction is
not
needed when Pm6847=0.
