+EL,
-EL
signal
When
an
end
limit
signal
(a
+EL
signal
when
feeding
in
the
+
direction)
in
the
feed
direction
turns
ON
while
operating,
the
axis
will
stop
immediately
or
decelerate
and
stop.
After
stopping,
even
if
the
EL
signal
is
turned
OFF,
the
axis
will
remain
stopped.
For
safety,
keep
the
EL
signal
ON
until
the
axis
reaches
the
end
of
the
stroke.
If
the
EL
signal
is
ON
when
writing
a
start
command,
the
axis
cannot
start
moving
in
the
direction
of
the
particular
EL
signal
that
is
ON.
By
setting
ELM
in
the
RENV1
(environment
setting
1)
register,
the
stopping
pattern
for
use
when
the
EL
signal
is
turned
ON
can
be
set
to
immediate
stop
or
deceleration
stop
(high
speed
start
only).
The
minimum
pulse
width
of
the
EL
signal
is
80
reference
clock
cycles
(4
μsec)
when
the
input
filter
is
ON.
When
the
input
filter
is
turned
OFF,
the
minimum
pulse
width
is
two
reference
clock
cycles
(0.1
μsec).
The
EL
signal
can
be
monitored
by
reading
SSTSW
(sub
status).
By
reading
the
REST
register,
you
can
check
for
an
error
interrupt
caused
by
the
EL
signal
turning
ON.
When
in
the
timer
mode,
this
signal
is
ignored.
Even
in
this
case,
the
EL
signal
can
be
monitored
by
reading
SSTSW
(sub
status).
The
input
logic
of
the
EL
signal
can
be
set
for
each
axis
using
the
ELL
input
terminal.

SD
signal
If
the
SD
signal
input
is
disabled
by
setting
MSDE
in
the
PRMD
register
(operation

the
SD
signal
will
be

If
the
SD
signal
is
enabled
and
the
SD
signal
is
turned
ON
while
in
operation,
the
axis
will:
1)
decelerate,
2)

-
While
feeding
at
low
speed,
the
SD
signal
is
ignored.
While
in
high
speed
operation
the
axis
decelerates
to
the
FL
speed
when
the
SD
signal
is
turned
ON.
After
decelerating,
or
while
decelerating,
if
the
SD
signal
turns
OFF,
the
axis
will
accelerate
to
the
FH
speed.
-
If
the
SD
signal
is
turned
ON
when
the
high
speed
command
is
written,
the
axis
will
operate
at
FL
speed.
When
the
SD
signal
is
turned
OFF,
the
axis
will
accelerate
to
FH
speed.
