M1: Kinematics transformation
2.8 Activating transformation machine data via part program/softkey
MD24100 $MC_TRAFO_TYPE_1 = 16
; orientation transformation 1: Orientation transformation data set
MD24200 $MC_TRAFO_TYPE_2 = 256 : Transmit transformations
MD24300 $MC_TRAFO_TYPE_3 = 18
; orientation transformation 2: Orientation transformation data set
The first data set for orientation transformations is assigned to the first transformation (at the
same time, the first orientation transformation) - and the second transformation data set to the
third transformation (at the same time, the the second orientation transformation).
If the third transformation is active when executing the "Activate machine data" function, then
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 $MC_TRAFO_RESET_VALUE
This may result in the generation of an alarm, for example, at the end or start of a program, if
the machine data of an active transformation has been altered.
To avoid this problem when re-configuring transformations via an NC program, we therefore
recommend that NC programs are structured as follows:
Program code
N10 TRAFOOF()
N20$MC_TRAFO5_BASE_TOOL_1[0]=0
N30$MC_TRAFO5_BASE_TOOL_1[0]=3
N40$MC_TRAFO5_BASE_TOOL_1[0]=200
