Assignment to channel axes
Machine data TRAFO5_ORIAX_ASSIGN_TAB_1[0..2] (ORI/channel assignment
Transformation 1) are used to assign up to a total of 3 virtual orientation axes to the channel,
which are set as input variables in machine data $MC_TRAFO_AXES_IN_n[4..6] (axis
assignment for Transformation n).
For assigning channel axes to orientation axes, the following applies:
• $MC_TRAFO5_ORIAX_ASSIGN_TAB_n[0] = $MC_TRAFO_AXES_IN_n[4]
• $MC_TRAFO5_ORIAX_ASSIGN_TAB_n[1] = $MC_TRAFO_AXES_IN_n[5]
• $MC_TRAFO5_ORIAX_ASSIGN_TAB_n[2] = $MC_TRAFO_AXES_IN_n[6]
Orientation transformation 1:
MD24585 $MC_TRAFO5_ORIAX_ASSIGN_TAB_1[n]
Orientation transformation 2:
MD24685 $MC_TRAFO5_ORIAX_ASSIGN_TAB_2[n]
transformation [1..4]
MD24110 $MC_TRAFO5_AXES_IN_1[n] (axis
assignment for transformation)
to
MD24410 $MC_TRAFO5_AXES_IN_4[n] (axis
assignment for transformation 4)
transformation [5..8]
MD24432 $MC_TRAFO5_AXES_IN_5[n] (axis
assignment for transformation 5)
to
MD24462 MC_TRAFO5_AXES_IN_8[n] (axis
assignment for transformation 8)
Example
For orientation axes, please see Chapter "Example for Orientation Axes".
2.9.1 JOG mode
It is not possible to traverse orientation axes in JOG mode until the following conditions are
fulfilled:
• The orientation axis must be defined as such, that is, a value must be set in the following
• A transformation must be active (TRAORIcommand)
Special functions: 3-Axis to 5-Axis Transformation (F2)
