ADVANCED POSITIONING CONTROL
10.1.1 Data required for advanced positioning control
"Advanced positioning control" is executed by setting the required items in the "start
block data" and "condition data", then starting that "start block data". Judgment about
whether execution is possible, etc., is carried out at execution using the "condition
data" designated in the "start block data".
"Start block data" can be set for each No. from 7000 to 7010 (called "block Nos."), and
up to 50 points can be set for each axis. (This data is controlled with Nos. called
"points" to distinguish it from the positioning data. For example, the 1st start block data
item is called the "1st point start block data" or "point No. 1 start block data".)
"Condition data" can be set for each No. from 7000 to 7010 (called "block Nos."), with
each block allowing up to 10 data to be set.
The "start block data" and "condition data" are set as 1 set for each block No.
The following table shows an outline of the "start block data" and "condition data"
stored in the D75P2.

Set whether to end the control after executing only the "start
block data" of the shape itself, or continue executing the "start
block data" set in the next point.
Set the "positioning data No." to be executed.
Set the method by which the positioning data set in Da.11
will be started.
Set the conditions by which the start will be executed
according to the commands set in Da.12 . (Designate the
"condition data No." and "No. of repetitions".)
Designate the "device", "buffer memory storage details", and
"positioning data No." elements for which the conditions are
set.
Set the judgment method carried out for the target set in
Da.14 .
Set the buffer memory address in which condition judgment is
carried out (only when the details set in Da.14 are "buffer
memory storage details").
Set the required conditions according to the details set in
