Detailed description
2.5 Activation and application of 3-axis to 5-axis transformation
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.
Option
The "5-axis transformation" function and its special types described in this Function Manual
are only available as an option. f this option is not implemented in the control system and a
transformation is called with the TRAORI command, error message 14780 "Block uses a
function that has not been enabled" appears and the NC program stops.
If the 3 to 5-axis transformation in the machine data:
MD24100 $MC_TRAFO_TYPE_1 (definition of Transformation 1 in the channel) ...
MD24460 $MC_TRAFO_TYPE_8 (Transformation 8 in the channel)
is not specified, the the programming of TRAORI (1 or 2) triggers Alarm 14100 "Channel x
block y orientation transformation not present".
If the following machine data is set without the 5-axis transformation option being enabled,
there is no alarm.
