Note
The transformation only takes place if the orientable toolholder concerned is available and
the value of $TC_CARR23 contains a valid entry for type M, P or T kinematics in lower or
upper case.
Transformation machine data for the first orientation transformation listed in the tables below
are equally valid for the second orientation transformation. All other machine data that may
affect the transformation characteristics and do not appear in the tables below, remain valid
and effective:
MD24110/MD24210 $MC_TRAFO_AXES_IN_1/2 (axis assignment for transformation) or
MD24574/MD24674 $MC_TRAFO5_BASE_ORIENT_1/2 (basic tool orientation)
If in the tables below a second additive parameter appears in brackets for the parameters of
the orientable toolholder (e.g. $TC_CARR24 (+ $TC_TCARR64)), the sum of both values will
only be effective if the fine offset specified in setting data is active when the data are
transferred from the orientable toolholder.
SD42974 $SC_TOCARR_FINE_CORRECTION = TRUE (fine offset TCARR on/off)
Activation
The most significant parameter values of an orientable toolholder for a transformation can be
activated in the part program with NEWCONFIG. Alternatively, the machine data concerned
for transformation type 72 can be activated via the HMI user interface.
