Address parameters
Coordinates can be programmed absolutely or incrementally. If you do
not make any entry for X, Y, Z, XK, YK, C, the coordinates of the block
previously executed will be retained (modal).
The control calculates missing coordinates in the principal axes X, Y or
Z if you program "?" (simplified geometry programming).
The machining functions G0, G1, G2, G3, G12 and G13 are modal. This
means that the control uses the previous G command if the address
parameters X, Y, Z, I or K in the following block have been
programmed without a G code. However, the address parameters
must have been programmed as absolute values.
The control supports the use of variables and mathematical
expressions as address parameters.
To edit address parameters:
 Call the dialog box.
 Position the cursor in the input field and enter/change the values, or
 Use the additional input options provided by the soft keys.
 "?" Simplified geometry programming
 Switch from incremental to absolute, or vice versa
 Activate variable input
 Load the contour reference.
