By inputting a user macro interrupt signal from the PLC, the program being currently executed is interrupted
and other programs can be called instead.
Retract or return operations when tools have been damaged, for instance, and other kinds of restoration
operations to be conducted when trouble has occurred are programmed in the interrupt programs.
There are two types of interrupts, type 1 and type 2, as described below, and they are selected using a
parameter.
[Interrupt type 1] The block being executed is immediately interrupted, and the interrupt program is
run immediately.
