Fanuc Power Mate i-D/H Operator Manual

(Common to Power Mate i–D and –H)
A custom macro interrupt is available only during program execution. It
is enabled under the following conditions
– When AUTO operation or MDI operation is selected
– When STL (start lamp) is on
– When a custom macro interrupt is not currently being processed
Generally, the custom macro interrupt function is used by specifying M96
to enable the interrupt signal (UINT) and M97 to disable the signal.
Once M96 is specified, a custom macro interrupt can be initiated by the
input of the interrupt signal (UINT) until M97 is specified or the
controller is reset. After M97 is specified or the NC is reset, no custom
macro interrupts are initiated even when the interrupt signal (UINT) is
input. The interrupt signal (UINT) is ignored until another M96
command is specified.

When UINT is kept on
The interrupt signal (UINT) becomes valid after M96 is specified. Even
when the signal is input in M97 mode, it is ignored. When the signal input
in M97 mode is kept on until M96 is specified, a custom macro interrupt
is initiated as soon as M96 is specified (only when the status–triggered
scheme is employed); when the edge–triggered scheme is employed, the
custom macro interrupt is not initiated even when M96 is specified.
For the status–triggered and edge–triggered schemes, see
Item “Custom macro interrupt signal (UINT)” of Subsec.
