Repeated Start (For Condition) - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

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
implemented until the conditions set in the condition data are established.
The condition judgment is implemented when switching to the point of 6: NEXT start (Before the positioning at the NEXT start
point) is implemented. (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 details
The positioning data No.1, 2, 3, 10, and 11 of the axis 1 are executed.
• Conditions not established: Implement "Positioning data No. 50 and 51", and go to
(1).
• Conditions established:Implement "Positioning data No. 50 and 51", and stop
positioning.
