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

Orientable tool holder with additive offset
On an orientable tool holder, 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 tool holder 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.

Modulo display of orientation axes

Function
The positions of orientation axes can be displayed for 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.
Preconditions
• Orientation axes must be available. This is the case if an orientation transformation is
active (e.g. generic 5-/6-axis transformation).
• The following MD must be set additionally for OEM transformations:
MD24585 $MC_TRAFO5_ORIAX_ASSIGN_TAB_1[0..2]
Parameter assignment
The modulo display of orientation axes is activated as follows:
MD21132 $MC_ORI_DISP_IS_MODULO[0...2] = TRUE
The modulo range is defined with the help of the following machine data:
