NOTE
1 When an axis not included in the tool–tip radius
compensation plane is specified in a G28, G30, or G30.1
command, a vector perpendicular to the direction in which
the tool moves is created at the end of the preceding block
and the tool does not move. Offset mode is automatically
resumed from the next block (in the same way as when two
or more blocks specifying no movement are consecutively
executed).
Example)
When bit 2 (CCN) of parameter No. 5003 is set to 1.

2 When a G28, G30, or G30.1 command is specified as a
start–up block, a vector perpendicular to the direction in
which the tool moves is created at the intermediate position.
The vector is then canceled at the reference position. The
next block creates an intersection vector.
Example 1)
When bit 2 (CCN) of parameter No. 5003 is set to 1.
