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 "co ndition data" are simultaneously executed
(pulses 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 "pos itioning
data" are set as shown in section [1].

It is assumed that the "axis 2 positioning data" for simultaneous starting is set in the
"condition data" designated with " Da.14 Parameter".

[2] Control examples
The following shows the control executed when the " block start da ta" o f th e 1 st
point of axis 1 is set as shown in section [1] and started.
<1> Simultaneously star t 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 s tart 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 simultaneous ly
started in <1>. Go to <3>.
Executing axis 2 positioning data simultaneo usly started in <1>.
"Error".
<3> Simultaneously st art 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 simultaneous ly
started in <2>. Go to <4>.
Executing axis 2 positioning data simultaneously started in <2>.
"Error".
<4> After the executi on of the axis 1 "positioning data No. 50" is c ompleted, stop
the control.
