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 "
FOR loop" is set in "
Da.13
Special start instruction" and the "block start data" in which
"6: NEXT start" is set in "
Da.13
Special start instruction " is repeatedly executed for
the No. of times set in "
Da.14
Parameter". An endless loop will result if the No. of
repetitions is set to "0".

[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.
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.
