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.

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.
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.
