ADVANCED POSITIONING CONTROL
This chapter describes the details and usage of the advanced positioning control (the control function using Block start data).
The advanced positioning control is used to implement applied controls using Positioning data, and examples of the applied
controls use the condition judgment to control the positioning data set using the major positioning control, or start positioning
data for multiple axes simultaneously.
Check the settings and execution procedures for each control, and configure each setting as required.
10.1

Overview of Advanced Positioning Control

For Advanced positioning control, the execution order and execution conditions of Positioning data are set to execute further
applied positioning. (The implementation order and execution conditions are set in the block start data and condition data.)
The following types of applied positioning controls can be implemented using advanced positioning control.
Advanced positioning
control
*1
Block start (normal start)
Condition start
Wait start
*2
Simultaneous start
Repeated start (FOR loop)
Repeated start (FOR condition)
*1 1 block is defined as all the data continuing from the positioning data in which continuous positioning control or continuous path control
is set in [Da.1] Operation pattern to the positioning data in which Independent positioning control (Positioning complete) is set.
*2 Besides the simultaneous start using Block start data, Multiple axes simultaneous start control of the control system is included.

Sub functions for advanced positioning control
Advance positioning control uses Positioning data set with Major positioning control.
For details on the sub functions that can be combined with the major positioning control, refer to the following.
Page 29 Combining Main and Sub Functions
Note that the pre-reading start function cannot be used together with Advanced positioning control.
Advanced positioning control from GX Works3
Advanced positioning control (start of block start data) can be implemented using the positioning test in the GX Works3. For
details on the positioning test, see the following.
Page 328 Positioning Test
Description
With one start, executes positioning data in a block in the set order.
Judges the condition set in Condition data for the specified positioning data, and executes Block start data.
• When the condition is established, Block start data is executed.
• When not established, that block start data is ignored, and the block start data of the next point is executed.
Judges the condition set in Condition data for the specified positioning data, and executes Block start data.
• When the condition is established, Block start data is executed.
• When not established, the control stops (waits) until the condition is established.
Simultaneously implements the positioning data for the axes specified using condition data (outputs pulses at the same
timing).
Repeats the program from the block start data set with FOR loop to the block start data set in NEXT for the specified
number of times.
Repeats the program from the block start data set with FOR condition to the block start data set in NEXT until the
conditions set in the condition data are established.
