Software
limit
function
A
software
limit
function
can
be
set
up
using
comparators
1
and
2.
Select
COUNTER1
(command
position)
as
a
comparison
counter
for
comparators
1
and
2.
Use
Comparator
1
for
a
positive
direction
limit
and
Comparator
2
for
a
negative
direction
limit
to
stop
the
axis
based
on
the
results
of
the
comparator
and
the
operation
direction.
When
the
software
limit
function
is
used
the
following
process
can
be
executed.
1)
Stop
pulse
output
immediately
2)
Decelerate
and
then
stop
pulse
output
While
using
the
software
limit
function,
if
a
deceleration
stop
is
selected
as
the
process
to
use
when
the
comparator
conditions
are
met
(C1D,
C2D),
when
an
axis
reaches
the
software
limit
while
in
a
high
speed
start
(52h,
53h),
that
axis
will
stop
using
deceleration.
When
some
other
process
is
specified
for
use
when
the
conditions
are
met,
or
while
in
a
low
speed
start,
that
axis
will
stop
immediately.
If
a
software
limit
is
ON
while
writing
a
start
command,
the
axis
will
not
start
to
move
in
the
direction
in
which
the
software
limit
is
enabled.
However,
it
can
start
in
the
opposite
direction.
[Setting
example]
RENV4=00003838h:
Use
Comparator
1
as
positive
direction
software
limit.
Use
Comparator
2
as
negative
direction
software
limit.
Set
to
stop
immediately
when
the
software
limit
is
reached.
RCMP1=
100,000:
Positive
direction
limit
value
RCMP2=
-100,000: Negative
