Axes and coordinate systems
7.1.2 Gantry axes
Gantry axes are any two axes that, due to the way the machine is built, must move together in
synchronism. For example: bridge type mills.
Only the movements of one of those axes must be programmed and it is called the main or master
axis. The other axis is referred to as "slave axis".
In order to operate this way, it is necessary to have the axis parameter GANTRY (P2) corresponding
to both axes set as follows:
• Parameter "GANTRY" of the main axis set to "0".
• Parameter "GANTRY" of the slave axis must indicate which axis is its "master" (or main axis).
Also, axis parameter MAXCOUPE (P45) of the slave axis must indicate the maximum allowed
difference between the following errors of both axes.
It is possible to have more than one pair of Gantry axes.
Example of a bridge type milling machine with two Gantry axes (X-U, Z-W).
