10 HIGH-LEVEL POSITIONING CONTROL

10.2 High-level positioning control execution procedure

MELSEC-Q

High-level positioning control is carried out using the following procedure.

Preparation

STEP 1

Refer to Chapter 9

	"High-level positioning control" executes each control
Carry out the "major positioning control" setting.	("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

Refer to Section 10.3

STEP 3

Refer to Section 10.4

STEP 4

Refer to Section 10.6

Set the block start data corresponding to each control.

( Da. 11 to ) × required data amount.

Set the "condition data"

( Da. 15 to Da. 19 ) × required data amount .

Create a sequence program in which "7000"*is set in the " Cd. 3 Positioning start No". (Control data setting)

Create a sequence 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)

Create a sequence program in which the "positioning start signal" is turned ON by a positioning start command.

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 QD75 recognizes that the control is high-level positioning control using " block start data" by the "7000" designation.

Use GX Developer to create a sequence program to execute the "high-level positioning control".

(Set the control data in the QD75 buffer memory using a TO command.)

Starting the control

Monitoring the control

Stopping the control

STEP 5

Refer to Chapter 6

STEP 6

Refer to Section 6.5.3

STEP 7

STEP 8

Refer to Section 6.5.6

Write the sequence programs to the PLC CPU.

Turn ON the "positioning start command" of the axis to be started.

Monitor the high-level positioning control.

Stop when control is completed

Write the sequence program created in STEP 4 to the PLC CPU using GX Developer.

Same procedure as for the "major positioning control" start.

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.

Control termination

REMARK

(1) Five sets of "block start data (50 points)" and "condition data (10 items) corresponding to "7000" to "7004" are set with a sequence 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

QD75, "7001" to "7004" can be set in " 4.

Cd.3

Positioning start No." in STEP
