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 perform applied controls using Positioning data. Examples of the applied controls
use the condition judgment to control the positioning data set with 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.
4.1
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 execution order and execution conditions are set in Block start data and Condition data.)
The following types of applied positioning controls can be executed by using Advanced positioning control.
*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.

Note that the pre-reading start function cannot be used together with Advanced positioning control.
Advanced positioning control from an engineering tool
Advanced positioning control (start of Block start data) can be executed using the positioning test of the engineering tool. For
details on the positioning test, refer to the following.

control Description
Block
*1
start (normal start) With one start, executes positioning data in a block in the set order.
Condition start 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.
Wait start 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.
Simultaneous start
*2
Simultaneously executes the positioning data for the axes specified with Condition data (outputs pulses at the same
timing).
Repeated start (FOR loop) 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.
Repeated start (FOR condition) 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 Condition data are established.
