Repeated start (FOR condition)
In Repeated start (FOR condition), the data between the block start data in which 5: FOR condition 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
until the conditions set in the condition data are established.
The condition judgment will be performed when switching to the point of 6: NEXT start (Before the positioning at the NEXT
start point) is performed.
(Specify the condition data in [Da.14] Parameter of the block start data in which 5: FOR condition is set in [Da.13] Special start
instruction.)
The following shows setting examples and a control example in which Block start data and Positioning data are set as shown
in the setting examples.

Control example
The following describes the control to be executed when the operation using the 1st point block start data of the axis 1 is
started.
*1 The condition judgment will be performed when switching to the point of 6: NEXT start (Before the positioning at the NEXT start point) is
performed.

Control details
(1)
-
The positioning data No.1, 2, 3, 10, and 11 of the axis 1 are executed.
(2)
The condition judgment set in the condition data No.5 of the
axis 1 is performed.
• Conditions not established: Positioning data No. 50 and 51 are executed and
processing proceeds on to (2).
• Conditions established: Positioning data No.50 and 51 are executed and the
positioning control ends.
