For a rotary axis, only the compensation values for the entries of 0° to +60°
are effective, relative to the machine datum. Therefore, the datum for the
nonlinear compensation must lie within the 0° to +360° range. To compensate
a full circle, set the compensation value datum on the machine datum.
Example: Rotary axis from –180° to +180°
