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]
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".
(The No. of repetitions is set in "[Da.14] Parameter" of the " block start data" in which "4: FOR loop" is set in "[Da.13]
Special start instruction".)
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.
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 No. of times (2 times) set in [Da.14].)
