Data required for advanced positioning control
Advanced positioning control is performed by setting the required items in Block start data and Condition data, and starting
the block start data. Whether or not the operations can be executed is judged at the execution of the control according to the
condition data specified in the block start data.
Block start data can be set for each number from 7000 to 7004 (called block No.), and up to 50 points can be set for each axis.
(This data is controlled with numbers called Points to distinguish it from the positioning data. For example, the 1st point block
start data item is called 1st point block start data or Point No. 1 block start data.)
Condition data can be set for each number from 7000 to 7004 (called block No.), and up to 10 data items can be set for each
block No.
Block start data and Condition data are set as one for each block No.
The following table shows the overview of Block start data and Condition data stored in the RD75.
Setting item Setting detail
Block start data [Da.11] Shape Set whether to end the control after only the block start data of the shape itself is executed, or to
continue executing the block start data set in the next point.
[Da.12] Start data No. Set Positioning data No. to be executed.
[Da.13] Special start
instruction Set the method by which the positioning data set in [Da.12] will be started.
[Da.14] Parameter Set the conditions by which the start will be executed according to the commands set in [Da.13].
(Specify Condition data No. or No. of repetitions.)
Condition data [Da.15] Condition target Select Device, Stored contents in buffer memory, and Positioning data No. elements for which the
conditions are set.
[Da.16] Condition operator Set the judgment method performed for the target set in [Da.15].
[Da.17] Address Set the buffer memory address in which the condition judgment is performed (only when the element
set in [Da.15] is Stored contents in buffer memory).
[Da.18] Parameter 1 Set the required conditions according to the elements set in [Da.15] and [Da.16].
[Da.19] Parameter 2 Set the required conditions according to the elements set in [Da.15] and [Da.16].
