Orientation Transformation And Orientable Tool Holders; Modulo Display Of Orientation Axes - Siemens SINUMERIK 840D sl Function Manual

Orientable toolholder with additive offset
On an orientable toolholder, the offset for both rotary axes can be programmed with the system
variables $TC_CARR24 and $TC_CARR25. This rotary axis offset can be transferred
automatically from the zero offset effective at the time the orientable toolholder was activated.
Automatic transfer of offset from zero offset is made possible via the following machine data:
MD21186 $MC_TOCARR_ROT_OFFSET_FROM_FR = TRUE (offset of TOCARR rotary axes
from NPV)

Orientation transformation and orientable tool holders

Note
Orientation transformation and orientable tool holders can becombined.
The resulting orientation of the tool is produced by linking the orientation transformation and
the orientable tool holder.
2.10.5

Modulo display of orientation axes

Function
The positions of orientation axes can be displayed for the BCS and WCS display in a settable
modulo area. Whether the concerned machine axes are linear or rotary is not relevant in this
context, i.e. this display option can be enabled even for normal generic 5-/6-axis
transformation.
Requirements
● Orientation axes must be available. This is the case if an orientation transformation is active
(e.g. generic 5-/6-axis transformation).
● The following machine data must also be set for OEM transformations:
MD24585 $MC_TRAFO5_ORIAX_ASSIGN_TAB_1[0..2]
