types
and
functions
This
LSI
has
5
circuits/axes
using
28-bit
comparators.
It
compares
the
values
set
in
the
RCMP1
to
5
registers
with
the
counter
values.
Comparators
1
to
4
can
be
used
as
comparison
counters
and
can
be
assigned
as
COUNTERS
1
to
4.
Comparator
5
can
be
assigned
as
COUNTER
1
to
4,
a
positioning
counter,
or
to
track
the
current
speed.
There
are
many
comparison
methods
and
four
processing
methods
that
can
be
used
when
the
conditions
are
met.
Specify
the
comparator
conditions
in
the
RENV4
(environment
4)
and
RENV5
(environment
5)
registers.
By
using
these
comparators,
you
can
perform
the
following.
Use
comparators
for
INT
