REFERENCE SYSTEMS
6.3.2 MACHINE REFERENCE (HOME) SEARCH (G74)
The axes may be programmed to be homed separately or together.
Home search on one axis.
Program function G74 followed by the axis to be referenced: G74 X or G74 Y.
Home search on both axes
Program G74 alone in a block.
The CNC starts homing the axes in the order established by machine parameter
P61(3).
If "P61(3)=0"
First X and then Y
If "P61(3)=1"
First Y and then X
Attention:
A block containing function G74 may not contain any other G function.
When homing in JOG mode, the currently active zero offset (part zero)
will be cancelled and the CNC will display the home coordinates set by
machine parameters "P2, P42".
In all other cases, the selected part zero will be maintained. Therefore,
the coordinates being displayed will be referred to that part zero.
Function G74 implies function G01 which means that after executing
G74 the CNC assumes function G01.
