Data Required For High-Level Positioning Control - Mitsubishi Electric MELSEC-L LD75P User Manual

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 block No.
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 LD75.

Set whether to end the control after executing only the "block start data" of the shape itself, or continue
executing the "block start 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.12] will be started.
Set the conditions by which the start will be executed according to the commands set in [Da.13].
(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.15].
Set the buffer memory address in which condition judgment is carried out (only when the details set in
[Da.15] are "buffer memory storage details").
Set the required conditions according to the details set in [Da.15] and [Da.16].
Set the required conditions according to the details set in [Da.15] and [Da.16].
