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 number of times set in "[Da.14] Parameter". An endless loop will result if the number of repetitions is set to
"0".
(The number 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".)
The control examples are shown when the "block start data" and "positioning data" are set as shown in the setting examples.
Setting examples
■Block start data setting example
The "condition data Nos." have been set in "[Da.14] Parameter".
■Positioning data setting example
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 the setting
examples 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 [Da.14].)
