WARNING
1 When a G28, G30, or G30.1 command is specified during all–axis machine lock, a
perpendicular offset vector is applied at the intermediate position, and movement to the
reference position is not performed; the vector is preserved. Note, however, that even if the
FS15 type is used, the vector is canceled only when each–axis machine lock is applied.
(The FS15 type preserves the vector even when each–axis machine lock is applied.)
Example1: When CCN (bit 2 of parameter No.5003)=1
and all–axis machine lock is applied
Example2: When CCN (bit 2 of parameter No.5003)=1
and each–axis machine lock is applied
2 When G28, G30, or G30.1 is specified for a compensation axis in cutter compensation mode,
the vectors along the other axes are also canceled. (This also applies when CCN (bit 2 of
parameter No. 5003) is set to 1. When the FS15 type is used, only the vector along a specified
axis is canceled. Note that the FS15 type cancellation differs from the actual FS15 specification
in this point.)
