5.5.3 Excluding axes in the zero offset (G157)
Excluding axes allows to select on to which axes the next absolute zero offset will not be
applied. After applying the zero offset, the programmed axis exclusion is canceled and it has
to be programmed again in order to apply it again.
Activation
Axis exclusion must be programmed using function G157 followed by the axes and the value
indicating whether that axis is excluded (<axis>=1) or not (<axis>=0).
The exclusion may also be activated by programming only the axes affected by the exclusion
after function G157.
The exclusion and the zero offset may be programmed in the same block. In that case, the
exclusion will be activated before applying the zero offset.
Excluding axes does not affect the active zero offsets. If an axis is excluded, when applying
a new zero offset, the CNC maintains the one that was active for that axis.
Considerations
Excluding axes does not affect the coordinate preset or the incremental zero offsets which
are always applied on to all the axes. Likewise, neither fixture offsets nor PLC offsets are
affected.
Function properties
Function G157 is modal and it remains active until an absolute zero offset is applied.
On power-up or after an EMERGENCY, the CNC does not assume any axis exclusion.
G55
(It applies the second zero offset on all the axes)
G157 X Z
(Activation of the exclusion on the X-Z axes)
G57
(It applies the fourth zero offset, except on the X-Z axes. Those axes keep the previous zero offset)
···
G159=8
(It applies the eighth zero offset on all the axes)
G59 G157 Y
(It applies the sixth zero offset, except on the Y axis. That axis keeps the previous zero offset)
···
G54
(It applies the first zero offset on all the axes)
