Siemens SINUMERIK 840D sl Function Manual page 53

This procedure can be used for all kinematics specified under "Kinematics Variants".
Observe the tips given in Figure "Projections of Vectors to be set in Machine Data".
Zero components
With certain geometries or machine zero positions, individual components or complete
vectors can become zero.
Machine type
The machine shown in Figure "Projections of Vectors to be set in Machine Data" corresponds
to variation 1. Therefore, type of transformation 64 must be set in the following machine data
(4 least-significant bits in MD).
$MC_TRAFO_TYPE_n
Activation
The transformation for a swiveled linear axis is activated in the same way as 5-axis
transformations. Details are described in Chapter "Activation and Application of 3- to 5-axis
Transformation".
Tool orientation
The same applies with regard to tool orientation, as described in Chapter "Tool Orientation".
