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
(reset/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 channel
transformation 1)
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.
