10 HIGH-LEVEL POSITIONING CONTROL
10.1.1 Data required for high-level positioning control
"High-level positioning control" is executed by setting the required items in the "block
start data" and "condition data", then starting that "block start data". Judgment about
whether execution is possible, etc., is carried out at execution using the "condition
data" designated in the "block start data".
"Block start data" can be set for each No. from 7000 to 7004 (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 block start data
item is called the "1st point block start data" or "point No. 1 block start data".)
"Condition data" can be set for each No. from 7000 to 7004 (called "block Nos."), and
up to 10 data items can be set for each axis.
The " block start data" and "condition data" are set as 1 set for each block No.
The following table shows an outline of the " block start data" and "condition data"
stored in the QD75.
