Idling
control
When
starting
an
acceleration
or
a
deceleration
operation,
it
can
be
started
after
the
output
of
a
few
pulses
at
FL
speed
(idling
output).
Set
the
number
of
pulses
for
idling
in
IDL
of
the
RENV5
register
(environment
setting
5).
If
you
will
not
be
using
this
function,
enter
a
value
"n"
of
0
or
1.
The
LSI
will
start
the
acceleration
at
the
same
time
it
begins
outputting
pulses.
Therefore,
the
start
speed
obtained
from
an
initial
2-pulse
frequency
will
be
faster
than
the
FL
speed.
To
use
this
function,
enter
a
value
"n"
of
2
to
7.
The
LSI
will
start
the
acceleration
by
beginning
its
output
on
the
"n"
th
pulse.
Therefore,
the
start
speed
will
be
the
FL
speed
and
the
FL
speed
can
be
set
to
start
automatically
at
upper
speed
limit.
If
this
function
is
used
with
the
positioning
mode,
the
total
feed
amount
will
not
change.
[Setting
idling
pulses
and
the
acceleration
start
timing]
Set
the
number
of
idling
pulses
<Set
IDL0
to
2
(bits
8
to
10)
in
RENV5>
Specify
the
number
of
idling
pulses,
from
0
to
7.
Start
accelerating
at
FL
speed
after
outputting
the
specified
number
of
pulses.

Note:
While
setting
the
number
of
idling
pulses,
when
you
write
a
High-Speed
Start
1
command
(52h
or
56h),
the
PCL
will
accelerate
to
FH
speed
after
outputting
the
specified
number
of
idling
pulses
at
FL
speed.
Then
the
operation
will
be
the
same
as
the
High-Speed
Start
2
command.
