Timer
operation
(MOD:
47h)
This
mode
allows
the
internal
operation
time
to
be
used
as
a
timer.
The
internal
effect
of
this
operation
is
identical
to
the
positioning
operation.
However,
the
LSI
does
not
output
any
pulses
(they
are
masked).
Therefore,
the
internal
operation
time
using
the
low
speed
start
command
will
be
a
product
of
the
frequency
of
the
output
pulses
and
the
RMV
register
setting.
(Ex.:
When
the
frequency
is
1000
pps
and
the
RMS
register
is
set
to
120
pulses,
the
internal
operation
time
will
be
120
msec.)
Write
a
positive
number
(1
to
134,217,727)
into
the
RMV
register.
The
±EL
input
signal,
SD
input
signal,
and
software
limits
are
ignored.
(These
are
always
treated
as
OFF.)
The
ALM
input
signal
input
signal,
and
input
signals
are
effective.
The
backlash/slip
correction,
vibration
restriction
function,
and
when
changing
direction,
this
timer
function
is
disabled.
The
LSI
stops
counting
from
COUNTER1
(command
position).
Regardless
of
the
MINP
setting
(bit
9)
in
the
RMD
(operation
mode)
register,
an
operation
complete
delay
controlled
by
the
INP
signal
will
not
occur.
In
order
to
eliminate
deviations
in
the
internal
operation
time,
set
the
METM
(bit
12)
in
the
PRMD
register
to
zero
and
use
the
cycle
completion
timing
of
the
output
pulse
as
the
operation
complete
timing.
