Chapter 10 High-Level Positioning Control
10.3.5 Simultaneous start
In a "simultaneous start", the positioning data set in the "[Da.12] Start data No." and
positioning data of other axes set in the "condition data" are simultaneously executed
(commands are output with the same timing).
(The "condition data" is designated with "[Da.14] Parameter".)
Section [2] shows a control example where the "block start data" and "positioning data"
are set as shown in section [1].
[1] Setting examples
(1) Block start data setting example
Axis 1 block
start data
[Da.11]
Shape
[Da.12]
Start data No.
[Da.13]
Special start
instruction
[Da.14]
Parameter
1st point 0: End 1 3: Simultaneous start 4
(Note): It is assumed that the "axis 2 positioning data" for simultaneous starting is set
in the "condition data" designated with "[Da.14] Parameter".
(2) Positioning data setting example
Axis 1 positioning
data No.
[Da.1]
Operation pattern
1 01: Continuous positioning control
2 01: Continuous positioning control
3 00: Positioning complete
[2] Control examples
The following shows the control executed when the "block start data" of the 1st
point of axis 1 is set as shown in section [1] and started.
<1> Check the axis operation status of axis 2 which is regarded as the
simultaneously started axis.
Axis 2 is standing by
Go to <2>.
Axis 2 is carrying out positioning.
An error occurs and simultaneous
start will not be carried out.
<2> Simultaneously start the axis 1 "positioning data No. 1" and axis 2
positioning data set in "condition data No. 4.
[3] Precautions
Positioning data No. executed by simultaneously started axes is set to condition
data ("[Da.18] Parameter 1", "[Da.19] Parameter 2"), but the setting value of start
axis (the axis which carries out positioning start) should be "0". If the setting
value is set to other than "0", the positioning data set in "[Da.18] Parameter 1",
"[Da.19] Parameter 2" is given priority to be executed rather than "[Da.12] Start
data No.".
