Parameter extensions
Parameters of the rotary axes
The system variables have been extended by the entries $TC_CARR24[m] to
$TC_CARR33[m] and described as follows:
Offset of rotary axes
v , v

The angle offset/
angle increment of
the rotary axes v
v
2
The minimum and
maximum position of
the rotary axes v

Parameters for the user
$TC_CARR34 to $TC_CARR40 contain parameters that are freely available to users and up
to SW 6.4 were as standard, not further evaluated within the NCK or had no significance.

Fine offset parameters
$TC_CARR41 to $TC_CARR65 include fine offset parameters that can be added to the
values in the basis parameters. The fine offset value assigned to a basic parameter is
obtained when the value 40 is added to the parameter number.
