10.3.8 Repeated start (FOR condition)
In a "repeated start (FOR condition)", the data between the "start block data" in which
"6: FOR condition" is set in "
Da.12 Special start command" and the "start block data"
in which "7: NEXT start" is set in " Da.12 Special start command" is repeatedly
executed until the establishment of the conditions set in the "condition data".
(The "condition data" designation is set in " Da.13 Parameter" of the "start block data"
in which "6: FOR condition" is set in " Da.12 Special start command".)
Section (2) shows a control example where the "start block data" and "positioning data"
are set as shown in section (1).

(2) Control examples
The following shows the control executed when the "start block data" of the 1st
point of axis 1 is set as shown in section (1) and started.
<1> Carry out the conditional judgment set in "condition data No. 5" for the axis 1
"positioning data No. 1".
Conditions not established Go to <2>.
Conditions established Go to <3>.
<2> Execute axis 1 "positioning data No. 1, 2, 3, 10, 11, 50, and 51", then go to
<1>.
<3> Execute axis 1 "positioning data No. 1, 2, 3, 10, 11, 50, and 51", then stop
