10.3.6 Repeated start (FOR loop)

In a "repeated start (FOR loop)", the data between the "block start data" in which "4:
FOR loop" is set in " Da.13
"6: NEXT start" is set in "
the number of times set in "
number of repetitions is set to "0".
(The number of repetitions is set in "
which "4: FOR loop" is set in "
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> Execute the axis 1 "positioning data No.1, 2, 3, 10, 11, 50, and 51".
<2> Return to the axis 1 "1st point block start data". Again execute the axis 1
"positioning data No.1, 2, 3, 10, 11, 50 and 51", and then stop the control.
(Repeat for the number of times (2 times) set in
