The tool function is also called the T function, and is used to command the tool No. in the lathe
specification controller, the tool compensation (tool length offset, tool nose wear compensation)
Nos. are also indicated.
The user PLC receives the T code data 1 with this signal.

The signal turns ON when:
(1) The T function (T code) is specified in automatic operation (memory or MDI).
(2) T function (T) is specified by manual numerical command input.
The signal turns OFF when:
(1) "M function finish 1" signal (FIN1) or "M function finish 2" signal (FIN2) turns ON.
