Chapter 3 Before positioning
3- 47
(4) Repeat Step
• Sets the step to repeat when the operation mode is set as Repeat.
• The setting range is 1~30 (1~80 for the compact standard/high-end type).
(5) Target Position
• Sets the movement of the operation of the step.
• The setting range is -2,147,483,648 ∼ 2,147,483,647 (unit: Pulse).
• The target position set in operation data setting can be freely changed in the program by changing
the value of area K for positioning.
• For the address of area K for positioning of each step number, see 2.2.
(6) M Code
• M code is for checking the current operation step or carrying out the auxiliary work such as tool
change, clamp, and drill rotation.
• In general, the output of M code divides into the ‘With’ mode, when M code is output with the step
operating, and the ‘After’ mode when M code is output after the step operation is completed.
For XGB built-in positioning, the standard type has only the After mode, and the advanced type has
all modes.
• For example, if M code output mode is set as the After mode, the positioning of the step is
completed and at the same time, the M code On signal (axis X: K4203(%KX6723), axis Y: K4303
(%KX6883)) is set and the M code number set in the M code item of the step operation data is
output in the M code output device (axis X: K428(%KW428), axis Y: K438(%KW438)).
• M code can be set differently for the operation steps of the positioning operation data. The setting
range is 1 ~ 65,535. If you don’t want to use M code function for the step, just set it at 0. If you don’t
want to use M code function for any step, set the M code output mode parameter as NONE.
• If there is the M code signal, you can reset it by using the M code Off instruction (MOF).
• If there is the M code signal, the operation differs depending on the current operation pattern.
(a) End: Stops with M code coming out. For operation of the next operation step, the M code should
be reset and the operation instruction should be executed.
(b) Continued: Enters the Stand-by status for operation of the next step with M code coming out.
For operation of the next operation step, if the M code is reset, the next operation step is
operated without additional operation instructions.
(c) Incessant: Does not stop and operates the next operation step although M code comes out. In
this case, M code Off instruction can be carried out even during operation.
• For example, the output timing of M code signals in case of After Mode can be illustrated as follows.
