G-MAS 2D and 3D Error Correction SupportYour Gain: The G-MAS corrects mechanism axis positions based on preset data that is accessed using user-defined correction table. Such corrections are possible for both single and multi-axis high level application solutions.
Used in: 2D error correction provides a correction point (x, y) on the basis of a standard two-
dimensional grid, defined as a function of any two axes positions. The correction point handles thee error for a specific axis.
3D error correction is similar to 2D error correction, but enables use of multiple, layered two-dimensional grids. As with 2D mode, the third axis correction point may be defined for any of the axes.
G-MAS error correction supports up to 6 two-dimensional tables and up to 100,000 tabulated correction positions. Correction points are pre-defined by a user during general setup.
