High-Level Positioning Control Execution Procedure
High-level positioning control is carried out using the following procedure.
*1 Five sets of "block start data (50 points)" and "condition data (10 items) corresponding to "7000" to "7004" are set with a
program.
Five sets of data from "7000" to "7004" can be set when GX Works2 is used. If GX Works2 is used to set the "block start
data" and "condition data" corresponding to "7000" to "7004" and write the data to the LD75, "7000" to "7004" can be set
in "[Cd.3] Positioning start No." in STEP 4.

Preparation
Starting
the control
Carry out the "major positioning control" setting.
Control termination
Stopping
the control
Same procedure as for the "major
positioning control" stop.
Monitor the high-level positioning control.
Monitoring
the control
Write the programs to the CPU module.
Stop when control is completed
Use GX Works2 to create a program
to execute the "high-level positioning
control".
Monitor using GX Works2.
Cd.3
Create a program in which "7000
*1
" is set in
the " Positioning start No". (Control data setting)
Cd.4
Create a program in which the "block start
data point No. to be started" (1 to 50) is set in the
" Positioning start point No". (Control data setting)
Turn ON the "positioning start command" of
the axis to be started.
"High-level positioning control" executes
each control ("major positioning control")
set in the positioning data with the
designated conditions, so first carry out
preparations so that "major positioning
control" can be executed.
The 50 "block start data" points from 1 to
50 points can be set.
Set the "condition data" for designation
with the "block start data". Up to 10
condition data items can be set.
The LD75 recognizes that the control is
high-level positioning control using " block
start data" by the "7000" designation.
Set the block start data corresponding to each control.
( Da.11 to Da.14 required data amount. )
Create a program in which the "positioning
start signal" is turned ON by a positioning start
command.
Same procedure as for the "major
positioning control" start.
