Activate concatenated transformation
If another transformation was previously activated, it is implicitly deactivated by
TRACON().
Number of the concatenated transformation:
Type: INT
Range of val‐ 0 ... 2
ues:
Value: 0, 1
2
Not specified
Note:
Values not equal to 0, 1, 2 generate an error alarm.
Parameters for the concatenated transformations (e.g. 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 pa‐
rameter, even though it is not necessary to specify <Trafo_No>. For example
TRACON( , 3.7).
Deactivate the last activated (concatenated) transformation
Comment
; Activate first concatenated transformation.
; The previously active transformation is automatical-
ly deselected.
; The parameter for the inclined axis is 45°.
; Activate second concatenated transformation.
; The parameter for the inclined axis is 40°.
