Persistent transformation

Function
A persistent transformation is always active and has a relative effect to the other explicitly
selected transformations. Other selected transformation are computed as the first chained
transformation in relation to the persistent transformation.
Transformations such as
transformation must be parameterized in a chain with the persistent transformation by means
of
TRACON
programmed in the part program.

Selection and deselection
Persistent transformation is selected via the following machine data:
MD20144 $MC_TRAFO_MODE_MASK, Bit 0 = 1
MD20144 $MC_TRAFO_RESET_VALUE defines persistent transformation.
MD20140 $MC_TRAFO_RESET_VALUE=Number of the transformation data set of the
persistent transformation
In addition the following must be set (i.e. noted):
MD20110 $MC_RESET_MODE_MASK
Bit 0 = 1 (Bit 7 is evaluated)
Bit 7 =0 (MD20140 $MC_TRAFO_RESET_VALUE determines the transformation data set)
MD20112 $MC_START_MODE_MASK (MD20140 $MC_TRAFO_RESET_VALUE)
MD20118 $MC_GEOAX_CHANGE_RESET= TRUE (i.e. geometry axes are reset).
If this additional data is not parameterized correctly,
alarm 14404 is generated.
