Continuous manual feed, incremental feed, and manual handle feed can be used for interrupt.
For example, cutting along an axis can be interrupted to change the depth of cut on that axis during auto-
matic operation.
(ii) Setup interrupt
An interrupt is made by manual operation for an axis along which a tool is not moved during automatic op-
eration.
Continuous manual feed, incremental feed, and manual handle feed can be used for interrupt.
The interrupt type can be selected for each axis by parking signals (PK1, PK2, PK3, ...) input from the PMC.
Selecting the simultaneous automatic and manual mode
The table below lists the states of mode selection input signals to select the simultaneous automatic and manu-
al operation mode.

Either one is equal to 1. 1
Either one is equal to 1,
the J and H are equal to 1,

The following example shows the case where automatic operation is switched to simultaneous automatic and
manual operation starting with a certain block.
1 Program command Mxx; switches automatic operation to simultaneous automatic and manual operation.
Program command M∆∆ ; returns simultaneous automatic and manual operation to automatic operation.
Set parameters so that Mxx; and M∆∆ ; do not direct buffering the next block.

End signal
Set a signal (H, J, or S) high for selecting a manual mode after turning on signal MOVL for selecting simulta-
neous automatic and manual operation, or set them high at the same time.
The simultaneous automatic and manual mode is selected by the procedure described above.
For each axis, either a cutting axis interrupt or setup interrupt is selected by the state of the parking signal
for the axis when the simultaneous automatic and manual operation mode is selected. Specify the desired
interrupt type in the parking signal for each axis before turning on signal MOVL and a signal for selecting
a manual mode.
