5.10.3 Specifications of G28
The block of G28 is a special block which is made up in plural blocks internally. Therefore
when direction change is executed, the output of the auxiliary function is different from the
case of G00 and G01.
Example 1:
O7000;
G00 X10 Z10;
G28 U0 W0 M11;
M30;
In the case of above-mentioned example 1, it is shown that M code of default in O7000 is
M10. In the block of G28, the intermediate position is not moved from the start position. For
this case, even if direction change is executed while moving toward the reference position of
G28, M10 is not output at once. When returning to the start position of G28, M10 is output.
Example 2:
O7001;
G00 X0 Z0;
G28 X10. Z10. M11;
M30;
In the case of above-mentioned example 2, it is shown that M code of default in O7001 is
M10. In direction change till intermediate position (X10.Z10.) of the block of G28, M code is
output by the same specification of G00 and G01. However, in direction change after
intermediate position, M10 is not output at once. When returning to the intermediate
position of G28, M10 is output.
