(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
Restrictions
(1) An error "Control system LOOP setting error (error code: 545)" will occur if a
"0" is set for the repeat cycles.
(2) Even if LEND is absent after LOOP, no error will occur, but repeat processing
will not be carried out.
(3) Nesting is not allowed between LOOP-LEND's. If such setting is made, only the
inner LOOP-LEND is processed repeatedly.
