13.13 Tool Change Position Return
393
(2) After all necessary tool changing position return is completed by a G30.n command, tool
changing position return complete signal TCP (XC93) is turned on. When an axis out of those
having returned to the tool changing position by a G30.n command leaves the tool changing
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 changing 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 changing 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 changing 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 changing position return command is issued, tool offset data such as for tool
length offset and tool radius 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
changing position. To make the next axis return to the tool changing position, therefore, a
cycle start needs to be specified.
