6.5.1 Activating chained transformations
TRACON
A chained transformation is activated by:
TRACON(trf, par)
● trf:
Number of the chained transformation: 0 or 1 for first/only chained transformation. If
nothing is programmed here, then this has the same meaning as specifying value 0 or 1,
i.e., the first/only transformation is activated – 2 for the second chained transformation.
(Values not equal to 0 - 2 generate an error alarm).
● par
One or more parameters separated by a comma for the transformations in the chain
expecting parameters, for example, the angle of the inclined axis. If parameters are not
set, the defaults or the parameters last used take effect. Commas must be used to
ensure that the specified parameters are evaluated in the sequence in which they are
expected, if default settings are to be effective for previous parameters. In particular, a
comma is required before at least one parameter, even though it is not necessary to
specify trf. For example: TRACON( , 3.7).
TRACON( , 3.7).
If another transformation was previously activated, it is implicitly disabled by means of
TRACON().
6.5.2 Switching off a chained transformation
TRAFOOF
A chained transformation is switched off with TRAFOOF just like any other transformation.
6.5.3 Special characteristics of chained transformations
Tool data
A tool is always assigned to the first transformation in a chain. The subsequent
transformation then behaves as if the active tool length were zero. Only the basic tool
lengths set in the machine data (_BASE_TOOL_) are valid for the first transformation in the
chain.
Example
The chapter "Chained transformations" contains configuration examples for single
transformations and the transformation chains created from them.
