G74 Code Introduction
The reference point can be approached in the NC program with G74 code in Siemens CNC controller. The direction and speed of each axis are stored in machine data.
G74 requires a separate block and is non-modal. The machine axis identifier must be programmed!
In the block after G74, the previous G command of the “Interpolation type” group (G0, G1,G2, …) is active again.

|N10 G74 X=0 Y=0 Z=0|
Note : The programmed position values for X, Y, Z (any value, here = 0) are ignored, but must still be written.
