10 ADVANCED POSITIONING CONTROL
10.2 Advanced positioning control execution procedure
Advanced 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 "main positioning control" setting.
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.
STEP 2
Set the start block data corresponding to each control.
( Da. 10 to Da. 13 ) × required data amount.
* 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.
STEP 3
Set the "condition data"
( Da. 14 to Da. 18 ) × required data amount .
* 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))
STEP 4
Create a sequence program in which "7000"*is set in
the "Positioning start No. (RWwm, RWwm+8)."
STEP 5
Refer to Chapter 6
* 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.
STEP 6
* Monitor using the AD75 software package.
STEP 7
Create a sequence program in which the "positioning
start signal" is turned ON by a positioning start command.
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)
Write the sequence 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 advanced positioning control.
Refer to Section 10.3
Refer to Section 10.5
Refer to Section 10.4
Refer to Section 6.6.3
Refer to Section 6.6.5
* Same procedure as for the "main positioning control" stop.
