The
compensation
is
performed
after
the
written
values
have been
multiplied
by
"n."
"n"
must not
be
greater
than
"5"
(n
<
5).

A.
The
following
conditions
must
be
satisfied
for
the
operation
of
leadscrew
error
com¬
pensation.

been
performed
for
the

axis
(not
set
by

to
"0")
after
power
on.
Note:
When the
contents
of
parameter
No.
06
are
"l,"
if
CYCLE
START
button
is
depressed
before
performing
reference
zero
return,
the alarm
code
"23"
will
be
displayed.

When
the
conditions
above
described
are
satisfied,
the
leadscrew
error
compensa¬
tion
is
effective
to
any
motions
in

ic
and
manual

The
compensation
is
performed
after
the
written

have
been
multiplied
by
"one.

Note
that
the

NOTES:
-
When
the
optional
fourth
axis is
a
rotary
axis,
the
compensation
is
not
effective
to
the
fourth
axis,
but
the
fourth
axis
is
a
linear
axis,
it
is
effective
.

When
the
fourth
axis
is
a
rotary
axis,
even
if
the
