(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
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 "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.

Restrictions
(1) Ignore the "LEND" before the "LOOP" is executed.
(2) When the operation pattern "Positioning complete" has been set between
LOOP and LEND, the positioning control is completed after the positioning
data is executed, and the LOOP control is not executed.
