NOTE
1 When an axis not included in the tool–tip radius
compensation plane is specified in a G53 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).

Start–up
2 When a G53 command is specified as a start–up block, the
next block actually becomes the start–up block. When bit
2 (CCN) of parameter No. 5003 is set to 1, however, the next
block creates an intersection vector.

Start–up
When a G28, G30, or G30.1 command is executed in tool–tip radius
compensation mode, the operation specified in the command is
performed according to the FS15 format if bit 2 (CCN) of parameter No.
5003 is set to 1. An intersection vector is created at the end of the
preceding block and a perpendicular vector is created at the intermediate
position. The offset vector is canceled when the tool moves from the
intermediate position to the reference position. The offset vector is
restored as an intersection vector by the next block.
