Activation and application of 3-axis to 5-axis transformation

Switch on
3-axis to 5-axis transformations (including the transformations for swiveled linear axis and
universal milling head) are activated with the TRAORI(n) command, where n represents the
number of the transformation (n = 1 or 2).
Once the TRAORI(n) command has been executed and the transformation thus activated,
the following interface signal is set to "1":
DB21, ... DBX33.6 (transformation active)
If the machine data has not been defined for an activated transformation grouping, the NC
program stops and the control system displays the alarm 14100 "Orientation transformation
does not exist".
Deactivation
TRAFOOF or TRAFOOF() de-activates the currently active 3- to 5-axis transformation. This
sets the interface signal to "0":
DB21, ... DBX33.6 (transformation active)
Switch-over
A switch-over can be made from one active transformation to another transformation
configured in the same channel. To do this the TRAORI(n) command must be entered again
with a new value for n.
RESET/end of program
The behavior of the control system with regard to 3-axis/5-axis transformations after run-up,
end of program or RESET, is determined by machine data:
MD20110 $MC_RESET_MODE_MASK (specifying control basic setting na)
Bit 7: Reset behavior of "active kinematic transformation"
Bit 7=0:
Basic setting for active transformation after program end of the parts program or RESET
according to MD20140 $MC_TRAFO_RESET_VALUE (transformation data set run-up
(RESET/parts program end)) is designated with the following meaning:
0: After RESET no transformation is active
1 to 8: the set transformation according to machine data MD24100 $MC_TRAFO_TYPE_1
(transformation definition 1 in the channel) to machine data MD24460 $MC_TRAFO_TYPE_8
(transformation 8 in the channel) is active.
Bit 7=1:
Current setting for the active transformation is retained beyond RESET/end of parts program.
