Transformations
7.12 Chained transformations (TRACON, TRAFOOF)
Job planning
Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
7-79
Parameters
TRACON This activates the chained transformation. If another transformation was
previously activated, it is implicitly disabled by means of TRACON().
TRAFOOF The most recently activated (chained) transformation will be disabled.
trf Number of the chained transformation:
0 or 1 for first/single chained transformation.
If nothing is programmed here, then this has the same meaning as
specifying value 0 or 1, i.e., the first/single 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).
Requirements
The second transformation must be "Inclined axis" (TRAANG). The first transformation can
be:
• Orientation transformations (TRAORI), including universal milling head
• TRANSMIT
• TRACYL
• TRAANG
It is a condition of using the activate command for a chained transformation that the
individual transformations to be chained and the chained transformation to be activated are
defined by the machine data.
The supplementary conditions and special cases indicated in the individual transformation
descriptions are also applicable for use in chained transformations.
Information on configuring the machine data of the transformations can be found in:
/FB2/ Function Manual Extended Functions; Kinematic Transformations (M1) and
/FB3/ Function Manual, Special Functions; 3- to 5-Axis Transformations (F2).
