Programmable Offset For Orientation Axes - Siemens SINUMERIK 840DE sl Function Manual

F2: Multi-axis transformations
3.10 Orientation axes
Range of values
Value range for orientation axes:
● 180 degrees < A2 < 180 degrees
● 90 degrees < B2 < 90 degrees
● 180 degrees < C2 < 180 degrees
All possible rotations can be represented with this value range. Values outside the range are
normalized by the control system to within the range specified above.
Feedrate when programming ORIAXES
Feedrate for an orientation axis can be limited via the FL[ ] instruction (feed limit).

Programmable offset for orientation axes

How the programmable offset works
The additional programmable offset for orientation axes acts in addition to the existing offset
and is specified when transformation is activated. Once transformation has been activated, it
is no longer possible to change this additive offset and no zero offset will be applied to the
orientation axes in the event of an orientation transformation.
The programmable offset can be specified in two ways.
1. Direct programming of the offset with TRAORI() when transformation is activated.
2. Automatic transfer of the offset from the zero offset active for the orientation axes when
transformation is activated. This automatic transfer is configured via machine data.
Programming offset directly
When transformation is activated, the offset can be programmed directly as TRAORI(n, x, y, z,
a, b) TRAORI(n, x, y, z, a, b) . The following parameters are available as an option:
n:
x, y, z
a, b:
These optional parameters can be omitted. However, if they are used for programming
purposes, the correct sequence must be observed. If for example only one rotary axis offset is
to be entered, TRAORI(,,,, a, b) is to be programmed.
