POINTS
I
(1) For continuous positioning, pattern 11 should not
be used more
than nine times consecutively. Where a large number of consecu-
tive 11 patterns are being used, they must be broken down by
placing 01 pattern data every nine 11 patterns. (e.g. pattern 11
= 9
times, pattern 01
=
1 time, pattern 11
=
9 times, pattern 00
=
1 time).
(2) Always set pattern 00 in the final data block.
(3) While pattern 11 is continuing, the direction of movement and the
positioning method should remain unchanged, only after pattern
01
or
00
may these be changed.
I f
the speed is changed after decel-
eration has started, the new speed is ignored and, if the M code
has been set in WITH mode, the "M code
ON"
signal is not given.
(4) During positioning using pattern 11, dwell time data and
M code will
be ignored.
(5) Interpolation positioning cannot be specified when
pattern I 1 is
being used.
(6)
Pattern 11 and pattern 01 cannot be used in the speed/positioning
control switching mode.
If
positioning patterns 11 and 01 are set during positioning control
in the speed/positioning control switching mode, all positioning
patterns will be executed as pattern 00.
