If the following command is specified in the offset mode, the offset mode
is temporarily canceled then automatically restored. The offset mode can
be canceled and started as described in Subsections 15.6.2 and 15.6.4.
If G28 is specified in the offset mode, the offset mode is canceled at an
intermediate position. If the vector still remains after the tool is returned
to the reference position, the components of the vector are reset to zero
with respect to each axis along which reference position return has been
made.
