4.3.11 LOOP to LEND control
Repeat control by repetition (LOOP to LEND)
(1) The LOOP to LEND loop is repeated for the set number of cycles.
(2) The repeat cycles are set to 1 to 65535 in the M code column.
(3) When LOOP is selected as the control system, settings other than the repeat
cycles (M code column) are ignored.
(4) When LEND is selected as the control system, the settings of other items are
ignored.
(5) 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 will be ignored.)
To stop the operation after the operation has been repeated for the designated
number of times, set the dummy positioning data (for example, incremental
positioning without movement amount) next to LEND.
