Lend - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

LEND

The operation is returned to the head of the repeating loop (LOOP to LEND).
Operation
The loop is completed when the number of repetition specified in LOOP is 0 and the processing of the next positioning data
No. is executed. (Even if the operation pattern is set to "Positioning complete", the setting is ignored.)
To stop the operation after the implementation for the specified number of repetitions, set a dummy positioning data (for
example, the positioning in the incremental system whose movement amount is 0).
The following table shows the operation for when Positioning complete (00) is set to LOOP and LEND.

Restrictions
• The LEND before the execution of LOOP is ignored.
• If the operation pattern Positioning complete is set between LOOP and LEND, the positioning control is completed after the
implementation of that positioning data and the loop control is not performed.
