12 DATA USED FOR POSITIONING CONTROL
12.4 Positioning Data
[Da.10] M code
Set M code, Number of pitch, Condition data No., or Number of LOOP to LEND repetitions depending on how [Da.2] Control
method is set.
• If a method other than JUMP instruction and LOOP is selected as the setting value in [Da.2] Control method, set M code. If
M code does not need to be output, set 0 (default value).
• If 3-axis helical interpolation control is selected as the setting value in [Da.2] Control method, set the number of pitch for the
linear interpolation axis. The rotation speed of the circular interpolation is set with the number of pitch.
• If JUMP instruction is selected as the setting value in [Da.2] Control method, set Condition data No. for JUMP. When 0 is
set, an unconditional JUMP is performed to the positioning data specified by the value set in [Da.9] Dwell time. When 1 to
10 is set, JUMP is performed according to the condition data No. specified (a number between 1 and 10).
• If LOOP is selected as the setting value in [Da.2] Control method, set the number of LOOP to LEND repetitions. If 0 is set,
Control method LOOP setting error (Error code: 1A33H) occurs.

■
Setting range
The setting range depends on the setting of [Da.2] Control method.
■
Default value
The default value is 0 for all the axes.
[Da.27] M code ON signal output timing
Set the M code ON signal output timing for each positioning data.
For details on the settings, refer to the following.
 Page 395 [Pr.18] M code ON signal output timing
■ Configuration of positioning option
The positioning option consists of [Da.27] M code ON signal output timing to [Da.29] Interpolation speed specification method.
These three setting values are stored in a buffer memory address. Set the values in [Da.27] M code ON signal output timing to
[Da.29] Interpolation speed specification method according to the configuration of positioning option shown in the following
figure.

Default value
The default value is 0: Use the setting value in [Pr.18] M code ON signal output timing for all the axes.
