These bits are turned ON to perform a manual origin search. Overrides are
ignored in manual origin searches.
If a reference origin offset is specified in the system parameters, the axis will
be moved that distance from the mechanical origin by PTP control after the
mechanical origin is detected. At this point, the high-speed feed rate, acceler-
ation time, and deceleration time will be used and overrides will be valid. The
position after the movement will be the origin of the reference coordinate sys-
tem.
Origin Search Bits are ignored when the Busy Flag is ON. The origin search
operation will be stopped if the Origin Search Bit is turned OFF while the
search is in progress. Keep the bit ON until the No Origin Flag turns OFF.
When the Origin Search Method machine parameter has been set to set the
origin at power ON, that position will be the origin for manual origin searches.

Starts the origin search.
Stops the origin search if it is in progress.
