10 HIGH-LEVEL POSITIONING CONTROL
10.3.4 Wait start
In a "wait 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" is executed. If the conditions
have not been established, the control stops (waits) until the conditions are
established.
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. 3" 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
Control stops (waits) until conditions are
established Go to <1>.
<2> Execute the axis 1 "positioning data No. 10, 11, 12, and 50" and stop the
control.
