9 MAJOR POSITIONING CONTROL
9.2.23 LEND
The LEND is used to return the operation to the top of the repeat (LOOP to LEND)
loop.
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 "termination", 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.
