Kinematic Transformation (M1)
Chained transformations
Constraints
The supplementary conditions and special cases indicated in the individual transformation
descriptions are also applicable for use in chained transformations.
7.5.1 Activating chained transformations
TRACON
A chained transformation is activated by:
TRACON(trf, par)
● trf:
● par
If another transformation was previously activated, it is implicitly disabled by means of
TRACON().
7.5.2 Switching off a chained transformation
TRAFOOF
A chained transformation is switched off with TRAFOOF just like any other transformation.
558
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).
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).
