10 HIGH-LEVEL POSITIONING CONTROL
10.2 High-level positioning control execution procedure
High-level positioning control is carried out using the following procedure.
STEP 1
Preparation
Starting the control
Monitoring the control
Refer to Chapter 9
Carry out the "major positioning control" setting.
Control termination
"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.
STEP 2
Set the block start data corresponding to each control.
( Da. 11 to Da. 14 ) × required data amount.
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.
STEP 3
Set the "condition data"
( Da. 15 to Da. 19 ) × required data amount .
The QD75 recognizes that the control is high-level
positioning control using " block start data" by the
"7000" designation.
Use GX Developer to create a PLC program
to execute the "high-level positioning control".
(Set the control data in the QD75MH buffer memory using
a TO command.)
STEP 4
Create a PLC program in which "7000"*is set in
the
"
Cd. 3 Positioning start No.
"
(Control data setting)
STEP 5
Refer to Chapter 6
Write the
PLC
program created in STEP 4 to the
PLC CPU using GX Developer.
Same procedure as for the "major positioning control"
start.
STEP 6
Use one of the following two methods.
Method (1): Monitor using GX Configurator-QP.
Method (2): Monitor using GX Developer .
Same procedure as for the "major positioning control" stop.
STEP 7
Create a PLC program in which the "positioning
start signal" is turned ON by a positioning start command.
Create a PLC program in which the "block start
data point No. to be started" (1 to 50) is set in the
"
Cd. 4 Positioning start point No.
"
(Control data setting)
Write the
PLC
programs to the PLC CPU.
Turn ON the "positioning start command" of
the axis to be started.
Stopping the control
STEP 8
Stop when control is completed
Monitor the high-level positioning control.
Refer to Section 10.3
Refer to Section 10.6
Refer to Section 10.4
Refer to Section 6.5.3
Refer to Section 6.5.6
REMARK
(1) Five sets of "block start data (50 points)" and "condition data (10 items)
corresponding to "7000" to "7004" are set with a PLC program.
(2) Five sets of data from "7000" to "7004" can be set when GX Configurator-QP
is used. If GX Configurator-QP is used to set the "block start data" and
"condition data" corresponding to "7001" to "7004" and write the data to the
QD75MH, "7001" to "7004" can be set in " Cd.3 Positioning start No." in
STEP 4.
