Changing the assignment
The assignment of a transformation data set to a transformation is determined by the
sequence of entries in MD24100 $MC_TRAFO_TYPE_X. The first entry in the table is
assigned to the first transformation data set, and accordingly the second entry to the second
data set. This assignment may (and can) not be altered for an active transformation.
Example:
Three transformations are set, two orientation transformations and one Transmit
transformation, e.g.
MD24100 $MC_TRAFO_TYPE_1 = 16
; orientation transformation, 1st orientation trafo data set
MD24200 $MC_TRAFO_TYPE_2 = 256: Transmit transformations
MD24300 $MC_TRAFO_TYPE_3 = 18
; orientation transformation, 2nd orientation trafo data set
The first data set for orientation transformations is assigned to the first transformation
(equaling the first orientation transformation) and the second transformation data set to the
third transformation (equaling the second orientation transformation).
If the third transformation is active when the NEWCONFIG command is executed, it is not
permissible to change the first transformation into a transformation of another group (e.g.
TRACYL) since, in this case, the third transformation would then not become the second
orientation transformation, but the first.
In the above example, however, it is permissible to set another orientation transformation for
the first transformation (e.g. using MD24100 $MC_TRAFO_TYPE_1 = 32) or a
transformation from another group as the first transformation (e.g. using $MD24100
$MC_TRAFO_TYPE_1 = 1024, TRAANG), if the second transformation is changed into an
orientation transformation at the same time, e.g. with MD24200 $MC_TRAFO_TYPE_2 = 48.

Control response to power ON, mode change, RESET, block search, REPOS

With the aid of the following machine data it is possible to select a transformation
automatically in response to RESET (i.e. at end of program as well) and/or on program start:
MD20110 $MC_RESET_MODE_MASK
MD20112 $MC_START_MODE_MASK
and
MD20140 $MC_TRAFO_RESET_VALUE
This may result in the generation of an alarm, for example, at the end or start of a program, if
the machine data of an active transformation has been altered.
