3 MAJOR POSITIONING CONTROL
3.2 Positioning Data Setting

LEND
The operation is returned to the head of the repeating loop (LOOP to LEND).
Operation
The loop is completed when the number of repetition specified in LOOP is 0 and the processing of the next positioning data
No. is executed. (Even if the operation pattern is set to Positioning complete, the setting is ignored.)
To stop the operation after the execution for the specified number of repetition, set a dummy positioning data (for example, the
positioning in the incremental system whose movement amount is 0).
The following table shows the operation for when Positioning complete (00) is set to LOOP and LEND.
Positioning data to be set
To use the LEND instruction, set the following positioning data.
: Always set,
: Set as required,
: Setting not required
For details on the settings, refer to the following.
Restrictions
• The LEND before the execution of LOOP is ignored.
• If the operation pattern Positioning complete is set between LOOP and LEND, the positioning control is completed after the
execution of that positioning data and the loop control is not performed.
