Zero
return
operation
After
writing
a
start
command,
the
axis
will
continue
feeding
until
the
conditions
for
a
zero
return
complete
are
satisfied.
MOD:

When
a
zero
return
is
complete,
the
LSI
will
reset
the
counter
and
output
an
ERC
(deflection
counter
clear)
signal.
The
RENV3
register
is
used
to
set
the
basic
zero
return
method.
That
is,
whether
or
not
to
reset
the
counter
when
the
zero
return
is
complete.
Specify
whether
or
not
to
output
the
ERC
signal
in
the
RENV1
register.
For
details
about
the
ERC
signal,
see
11-6-2,
"ERC
signal."
