3 MAJOR POSITIONING CONTROL
3.2 Positioning Data Setting
LOOP
The loop control with repetition of the LOOP to LEND instructions is performed.
Operation
The loop of LOOP to LEND is repeated for the set number of the repetition.
Positioning data to be set
To use the LOOP instruction, set the following positioning data.
: Always set,
: Set as required,
: Setting not required
For details on the settings, refer to the following.
Restrictions
• If 0 is set for the number of repetition, Control method LOOP setting error (Error code: 1A33H) occurs.
• Although the error does not occur even if LEND is not set after LOOP, the repetition is not processed.
• The nesting between LOOP and LEND cannot be set. If the nesting is set, only the inner LOOP to LEND are processed
repeatedly.
The setting becomes easier than the special start FOR (times) by setting required items in the control method.
(
Page 164 Repeated start (FOR loop))
• Special start: Positioning start data, special start data, condition data, and positioning data
• Control method: Positioning data
For the special start FOR to NEXT, positioning data is required for each point of FOR and NEXT. However, the
loop is available with only one data in the control method.
The nesting is available by combining the control method LOOP to LEND and the special start FOR to NEXT.
However, LOOP to LEND cannot be set across the blocks. Set the processing of LOOP to LEND to be
finished in one block.
For details on Block, refer to the following.
