LEND

The LEND is used to return the operation to the top of the repeat (LOOP to LEND) loop.
(1) Operation
When the repeat cycle designated by the LOOP becomes 0, the loop is terminated, and the next positioning data
No. processing is started. (The operation pattern, if set to "Positioning complete", will be ignored.)
When the operation is stopped after the repeat operation is executed by designated cycles, the dummy
positioning data (for example, incremental positioning without movement amount) is set next to LEND.
The operation for the case when Positioning complete (00) is set to LOOP or LEND is shown below.
