NOTE
-
1.
This
function
is
optional.
Therefore,
it
is
not
effective
if
the
option
is
not
set.
2.
When
the
reference
point
return
is
executed
by
selecting
this
function,
do
not
fail
to
retract
the
deceleration
limit
switch
sufficiently.
If
the
distance
beyond
the
deceleration
limit
switch
is
too
short,
an
alarm
(2061
to
2065:
reference
point
return
area
error)
occurs.
3.
If
the
imaginary
phase-C
shift
distance
(pm4551
to
4555)
or
reference
point
return
traveling
distance
(pm4451
to'
4455)
set
value
is
not
proper.
retraction
is
generated
and
an
alarm
(2091
to
2095:
reference
point
return
parameter
error)
occurs.
In
this
case,
adjust
the
parameter
by increasing
the
reference
point
return
traveling
distance
set
value,
etc.
(Example
1)
When
the
distance
from
the
deceleration
limit
switch
to
the
imaginary
phase-C
pulse
becomes
larger
by
increas¬
ing
the
imaginary
phase-C
shift
distance.
.
(Example
2)
When
the
final
traveling
distance
set
value
is
minus
and
exceeds
the
distance
from
the deceleration
limit
switch
to
the
imaginary
phase-C
pulse.
4:
When
the
deceleration
limit
switch
is
turned
OFF
and
then
ON
at
reference
point
return
before
completion
of
phase-C
latch,
alams
2151
to
2155;
reference
point
return
phase-C
creation
error(axes
X
to
5th)
occur.
