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).
(1) Setting examples
(a) Block start data setting example
The "condition data Nos." have been set in "[Da.14] Parameter".
(b) Positioning data setting example
(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.
