WARNING
1 When a G28, G30, or G30.1 command is executed when
all–axis machine lock is applied, a vector perpendicular to
the direction in which the tool moves is created at the
intermediate position. In this case, the tool does not move
to the reference position and the offset vector is not
canceled. When bit 2 (CCN) of parameter No. 5003 is set
to 0 or each–axis machine lock is applied, the offset vector
is canceled.
Example 1)
When bit 2 (CCN) of parameter No. 5003 is set to 1.

2 When a compensation axis is specified in a G28, G30, or
G30.1 command in tool–tip radius compensation mode, the
vectors for other compensation axes are also canceled.
This also applies when bit 2 (CCN) of parameter No. 5003
is set to 1. (The FS15 cancels only the vector for the
specified axis. Note that the FS15 type cancellation differs
from the actual FS15 specification in this point.)
