2.4.2 "Home search" programming
When programming a "Home search", the axes are homed
sequentially in the order set by the operator. All the axes need not be
included in the "Home search", only those being homed.
The "Home search" is programmed using the G74 function followed
by the axes to be homed and the number indicating their homing order.
If the same order number is assigned to several axes, those axes start
homing at the same time and the CNC waits for all of them to end
before homing the next one.
When having numbered axes, they may be defined together with the
other ones by assigning them the order number as follows.
Spindle home search
When using a position controlled spindle, it may be included in the
"Home search" like any other axis. In this case, the spindle home
search is always carried out together with the first axis regardless of
the order in which it has been defined.
Using an associated subroutine
If the machine manufacturer has associated a home-search
subroutine to the G74 function, this function may be programmed
alone in the block and the CNC will automatically execute the
associated subroutine [G.M.P. "REFPSUB (G74)"].
When using a subroutine, the "Home search" is carried out exactly as
described earlier.
