Automatic/Manual Mode Bit
Operation
The manual mode origin search is stopped when the Automatic/Manual Mode Bit is turned ON. All axes in the task
are stopped and the Unit enters automatic mode. At this point, the Busy Flags for all of the axes will be OFF, even
though the Origin Search Bit remains ON.

Operation
While the OPTIONAL PROGRAM STOP function (G76) is being executed, the block is cancelled by turning ON
the Forced Block End Bit. The optional input is turned OFF at the same time that the Forced Block End Bit is turned
ON, so in the end the input has no effect.

Forced Block End Bit
Optional Input
Operation
While the block after the OPTIONAL END function (G74) is being executed, the block is cancelled by turning ON
the Forced Block End Bit. The optional input and Forced Block End Bit are turned ON at the same time, but the
Forced Block End Bit takes precedence.
