G49
(1) This command cancels the preset tool length offset value (G43, G44) and
performs the specified positioning.
(2) Be sure to set the positioning address for tool length offset cancel.
Power-on mode : At power-on, the tool length offset cancel mode is established.
The program designed to cancel the offset value and perform the specified positioning
after positioning has been executed by tool length offset. (For absolute value
command) (Data of the tool length offset data setting registers are as follows :
H1 = 5[mm] (D1650, 1651 = 50000), H2 = 10[mm] (D1652, 1653 = 100000))

Positioning address
Axis name
(Absolute value command)
(With the addition of the offset value of 5[mm], X-axis is
positioned to its 55[mm] position)
(X-axis travels to its 30[mm] position at 500[mm/min].)
(Y-axis travels to its 100[mm] position at 500[mm/min].)
(With the addition of the offset value of 10[mm], X-axis
travels to its 210[mm] position (offset value change))
(With the offset value canceled, X-axis travels to its
100[mm] position at 500[mm/min].)
