2.10 Orientation axes
Direction of the tool vector
The direction of the tool vector in the initial machine setting is defined in the following machine
data:
MD24580 $MC_TRAFO5_TOOL_VECTOR_1 (orientation vector direction) or
MD24680 $MC_TRAFO5_TOOL_VECTOR_2 (orientation vector direction)
Assignment to channel axes
Machine data MD24585 $MC_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, see Section "Example for orientation axes (Page 131)".
