ADVANCED POSITIONING CONTROL
10.3.5 Simultaneous start
In a "simultaneous start", the positioning data
positioning data of other axes set in the "condition data" are simultaneously executed
(Outputs pulses at the same timing).
(The "condition data" is designated with " Da.13 Parameter".)
Section (2) shows a control example where the "start block data" and "positioning data"
are set as shown in section (1).
*1 For the starting axis (axis where positioning start takes place), set the value to 0. A
value other than 0 results in the processing of the positioning data set in "
Parameter 1" and "

Control examples
The following shows the control executed when the "start block data" of the 1st
point of axis 1 is set as shown in section (1) and started.
<1> Simultaneously start the axis 1 "positioning data No. 1" and axis 2
positioning data set in "condition data No. 4". After the execution of axis 1
"positioning data No. 1, 2, and 3" is completed, go to <2>.
<2> Simultaneously start the axis 1 "positioning data No. 10" and axis 2
positioning data set in "condition data No. 5".
Standing by after completion of axis 2 positioning data simultaneously
started in <1>.
Executing other axis positioning data simultaneously started in <1>.
"Error".
<3> Simultaneously start the axis 1 "positioning data No. 50" and the axis 2
positioning data set in "condition data No. 6" after the completion of the
execution of axis 1 "positioning data No. 10, 11, and 12".
Standing by after completion of axis 2 positioning data simultaneously
started in <2>.
Executing axis 2 positioning data simultaneously started in <2>.
