12 DATA USED FOR POSITIONING CONTROL
12.4 Positioning Data
[Da.1] Operation pattern
The operation pattern designates whether positioning of a certain data No. is to be ended with just that data, or whether the
positioning for the next data No. is to be carried out in succession.
[Da.2] Control method
Set the "control method" for carrying out positioning control.
• When "JUMP instruction" is set for the control method, the "[Da.9] Dwell time/JUMP destination positioning
data No." and "[Da.10] M code/Condition data No./Number of LOOP to LEND repetitions/Number of
pitches" setting details will differ.
• In case you selected "LOOP" as the control method, the "[Da.10] M code/Condition data No./Number of
LOOP to LEND repetitions/Number of pitches" should be set differently from other cases.
• Refer to the following for details on the control methods.

• If "degree" is set for "[Pr.1] Unit setting", circular interpolation control and 3-axis helical interpolation control
cannot be carried out. (The error "Circular interpolation not possible" (error code: 199FH) will occur when
executed.)
[Da.3] Acceleration time No.
Set which of "acceleration time 0 to 3" to use for the acceleration time during positioning.
0: Use the value set in "[Pr.9] Acceleration time 0".
1: Use the value set in "[Pr.25] Acceleration time 1".
2: Use the value set in "[Pr.26] Acceleration time 2".
3: Use the value set in "[Pr.27] Acceleration time 3".

Operation pattern Setting value Details
Positioning complete 00 Set to execute positioning to the designated address, and then complete positioning.
Continuous positioning control 01 Positioning is carried out successively in order of data Nos. with one start signal. The operation halts at
each position indicated by a positioning data.
Continuous path control 11 Positioning is carried out successively in order of data Nos. with one start signal. The operation does
not stop at each positioning data.
