Chapter 10 High-Level Positioning Control
10.3.3 Condition start
In a "condition start", the "condition data" conditional judgment designated in " Da.14
Parameter" is carried out for the positioning data set in "
Da.12
Start data No.". If the
conditions have been established, the "block start data" set in "1: condition start" is
executed. If the conditions have not been established, that "block start data" will be
ignored, and the "block start data" of the next point will be executed.
Section [2] shows a control example where the "block start data" and "positioning data"
are set as shown in section [1].

[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> The conditional judgment set in "condition data No. 1" is carried out before
execution of the axis 1 "positioning data No.1".
Conditions established
Execute positioning data No. 1, 2, and 3
Go to <2>.
Conditions not established
Go to <2>.
<2> The conditional judgment set in "condition data No.2" is carried out before
execution of the axis 1 "positioning data No. 10".
Conditions established
Execute positioning data No.10, 11, and 12
Go to <3>.
Conditions not established
Go to <3>.
<3> Execute axis 1 "positioning data No.50" and stop the control.
