ADVANCED POSITIONING CONTROL
10.2 Advanced positioning control execution procedure
Preparation
STEP 1
Refer to Chapter 9
STEP 2
Refer to Section 10.3
STEP 3
Refer to Section 10.4
STEP 4
Refer to Section 10.5
STEP 5
Refer to Chapter 6
STEP 6
Starting the control
Refer to Section 6.6.3
STEP 7
Monitoring the control
Stopping the control
STEP 8
Refer to Section 6.6.5
Advanced positioning control is carried out using the following procedure.
Carry out the "main positioning control" setting.
Set the start block data corresponding to each control.
( Da. 10 to Da. 13 ) × required data amount.
Set the "condition data"
( Da. 14 to Da. 18 ) × required data amount .
Create a sequence program in which "7000"*is set in
the "Positioning start No. (RWwm, RWwm+8)."
Create a sequence program in which the "start block
data point No. to be started" (1 to 50) is set in the
" Cd. 31 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.
Write the sequence programs to the PLC CPU.
Turn ON the "positioning start command" of
the axis to be started.
Monitor the advanced positioning control.
Stop when control is completed
Control termination
* "Advanced positioning control" executes each control
("main positioning control") set in the positioning data
with the designated conditions,so first carry out
preparations so that "main positioning control" can be
executed.
* The 50 "start block data" points from 1 to 50 points
can be set.
* Set the "condition data" for designation with the
"start block data". Up to 10 condition data items
can be set.
* The D75P2 recognizes that the control is advanced
positioning control using "start block data" by the
"7000" designation.
Use the GPP function software package to create a
sequence program to execute the "advanced
positioning control".
(Set the control data in the D75P2 buffer memory using
a TO command.(dedicated command))
* Write the sequence program created in STEP 4 to the
PLC CPU using the GPP function software package.
* Same procedure as for the "main positioning control"
start.
* Monitor using the AD75 software package.
* Same procedure as for the "main positioning control" stop.
