None of the other settings of SD42980 $SC_TOFRAME_MODE (0,1,2,...1000,1001..) should
be used for recommissioning.
For compatibility reasons, the following settings remain valid:
0: The orientation of the coordinate system is determined by the value of machine data
21110 $MC_X_AXIS_IN_OLD_X_Z_PLANE.
1: The new X direction is selected so that it lies in the X-Z plane of the old
coordinate system. The angular difference between the old and new Y axes is minimal
with this setting.
2: The new Y direction is selected so that it lies in the Y-Z plane of the old
coordinate system. The angular difference between the old and new X axes is minimal
with this setting.
3: The average of the two settings resulting from 1 and 2 is selected.
Addition of 100: In the case of a plane change from G17 to G18 or G19, a tool matrix
is
generated, in
which the new axis directions are parallel to the old directions. The
axes are swapped cyclically accordingly (standard transformation on plane changes). If
the hundreds digit equals zero, a matrix is supplied in the cases of G18 and G19 which
is derived from the unit matrix by simply rotating through 90 degrees around the X axis
(G18) or through 90 degrees around the Y axis (G19). Thus in each case one axis is
antiparallel to an initial axis. This setting is required to remain compatible with
old software versions.
Addition of 1000: The tool-frame is linked to any active basic frames and settable
frames. The response is thus compatible with earlier software versions (before 5.3).
If the thousands digit is not set, the tool frame is calculated so that any active
basic frames and settable frames are taken into account.

Description: States whether the tool point direction and cutting direction are to be modified on
reading the corresponding system variables $P_AD[2] and $P_AD[11].
Modification is made by rotating the vector of the tool point direction or cutting
direction by a specific angle in the active machining plane (G17-G19). The resulting
output value is always the tool point direction or cutting direction created by the
rotation or to
which the rotated value is closest. the angle of rotation can be defined
by one of the following six options:
1: The string is empty. The stated data are output unchanged.
2: The contents of the string is "P_TOTFRAME". The resulting rotation is determined
from the total frame.
3: The contents of the string is a valid frame name (e.g. $P_NCBFRAME[3]). The
resulting rotation is then calculated from this frame.
4: The contents of the string has the form "Frame1 : Frame2". The resulting rotation
is determined from the part frame chain that is created by chaining all frames from
Frame1
to Frame2
(in each case inclusive). Frame1 and Frame2 are valid frame names such
as $P_PFRAME or $P_CHBFRAME[5]"
5: The contents of the frame is the valid name of a rotary axis (machine axis). The
resulting rotation is
determined from the programmed end position of this rotary axis.
Additionally, an offset can be stated (in degrees, e.g. "A+90).
6: The rotation is programmed explicitly (in degrees).
