10 HIGH-LEVEL POSITIONING CONTROL

10.3.5 Simultaneous start

In a "simultaneous start", the positioning data set in the "
positioning data of other axes set in the "condition data" are simultaneously executed
(pulses are output with the same timing).
(The "condition data" is designated with "
Section [2] shows a control example where the " block start data" and "positioning
data" are set as shown in section [1].

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> 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 axis 2 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>.
"Error".
<4> After the execution of the axis 1 "positioning data No. 50" is completed, stop
the control.
