2.6 Programming of the 3- to 5-axis transformation
Switch on
The 3- to 5-axis transformations, including the transformations with swiveled linear axis and
cardan milling head, are enabled with the TRAORI(<transformation-no.>) command.
The enable of the transformation sets the NC/PLC interface signal:
DB21, ... DBX33.6 = 1 (transformation active)
Deactivation
With the TRAFOOF command disables the currently active 3- to 5-axis transformation. The
disable of the transformation resets the NC/PLC interface signal:
DB21, ... DBX33.6 = 0 (transformation inactive)
Switch-over
If a transformation is already active in the channel, the TRAORI(<transformation-no.>)
with a new transformation number command can be used to switch to another transformation.
Reset / program end
The control behavior after startup, program end or NC reset is set in the machine data:
MD20110 $MC_RESET_MODE_MASK, bit 7 = <value>
<value>
Option
The "5-axis transformation" function, together with its special forms, is an option.
