Deactivating
The currently active transformation is deactivated by means of TRAFOOF or TRAFOOF().
Note
When the "Handling transformation package" transformation is deactivated, no preprocessing
stop and no synchronization of the preprocessing with the main run is performed.
RESET/end of program
The control behavior in terms of transformation following run-up, end of program or RESET
depends on machine data:
MD20110 $MC_RESET_MODE_MASK (definition of control basic setting na)
Bit 7:
Bit 7 = 0
Bit 7 = 1

Actual value display

MCS machine coordinate system
The machine axes are displayed in mm/inch and/or degrees in MCS display mode.
WCS workpiece coordinate system
If the transformation is active, the tool tip (TCP) is specified in mm/inch and the orientation by
the RPY angles A, B and C in WCS display mode. The tool orientation results from turning a
vector in the Z direction firstly with A around the Z axis, then with B around the new Y axis and
lastly with C around the new X axis.
If the transformation is deactivated, the axes will be displayed with the channel axis names.
Otherwise the geometry axis names will be displayed.

Reset behavior of "active kinematic transformation"
For this reason, the initial setting is defined for active transformation after the
end of part program or RESET, according to the following machine data:
MD20140 $MC_TRAFO_RESET_VALUE (transformation data block run-up (re‐
set/part program end))
Meaning:
0: After RESET no transformation is active.
1 to 8: The set transformation is active according to machine data:
MD24100 $MC_TRAFO_TYPE_1 (definition of transformation 1 in
the channel)
To machine data:
MD24460 $MC_TRAFO_TYPE_8 (channel transformation 8)
The current setting for the active transformation remains unchanged after a
RESET or end of part program.
