NOTE
1 When the number of actually stored data items is exceeded
even though data number n is in the valid range, data is not
output and processing ends successfully by number of data
items I set to 0.
Example) When the number of target axes is 2, and the
sample data store function is enabled
(parameter No.6350#2=1), data numbers 0 to
131071 are valid. However, if an attempt is
made to read (example (1) in figure below) data
from data number n = 131020 when the number
of actually stored data items is 131000 (data
numbers 0 to 130999), data is not output, and
the number of data items I becomes 0.
2 When data number n is within the number of actually stored
data items, and (n+I – 1) exceeds the number of actually
stored data items, data of the stored data items is output,
and processing ends successfully. In this case, number of
data items I is updated to the number of data items that was
output.
Example) If an attempt is made to read (example (2) in
figure below) number of data items I (120) from
data number 130900 under the same
conditions as in the example above, the data of
data numbers 130900 to 130999 is output, and
number of data items I becomes 100.
Also, if an attempt is made to read (example (3)
in figure below) number of data items I (120)
from data number 130999 under the same
conditions as in the example above, the data of
data numbers 130990 to 130999 is output, and
number of data items becomes 10.
