Overview

3D error compensation (SEC 3D) (option)

In addition to the "leadscrew error compensation", "sag compensation" and "temperature compensation" functions, "SEC 3D" provides a further static compensation which allows the machine manufacturer to improve the machine accuracy. The compensation data for SEC 3D are not based on an error model. Errors are measured with the aid of an external measuring instrument (e.g., a laser tracker) on spatial grid points dimensioned for the relevant machine. The control interpolates these compensation values while the machine moves within its working area limits.

Acceleration with jerk limitation

To achieve optimum acceleration with reduced wear on the machine's mechanical parts, you can select SOFT in the part program to ensure continuous, jerk-free acceleration. When you select “jerk-free acceleration”, the velocity characteristic over the path is generated as a sinusoidal-shaped curve.
