(2) After all necessary tool change position return is completed by a G30.n command, tool change
position return complete signal TCP (X64B) is turned on. When an axis out of those having
returned to the tool change position by a G30.n command leaves the tool change position, the
TCP signal is turned off.
With a G30.1 command, for example, the TCP signal is turned on when the Z axis has
reached the tool change position after the X and Y axes did (after the additional axis did if
additional axis tool change position return is valid). The TCP signal is then turned off when the
X or Y axis leaves the position. If tool change position return for added axes is on with
parameter "#1092 Tchg_A", the TCP signal is turned on when the added axis or axes have
reached the tool change position after the standard axes did. It is then turned off when one of
the X, Y, Z, and added axes leaves the position.

(3) When a tool change position return command is issued, tool offset data such as for tool length
offset and tool radias compensation for the axis that moved is canceled.
(4) This command is executed by dividing blocks for every axis. If this command is issued during
single-block operation, therefore, a block stop occurs each time one axis returns to the tool
change position. To make the next axis return to the tool change position, therefore, a cycle
start needs to be specified.
