$TC_CARR24 to $TC_CARR33
The system variables in $TC_CARR24 to $TC_CARR33 can be used to define offsets, angle
compensations, Hirth tooth system and axis limits.
Note
The system variables are available with and without active tool management.
Components and presetting of the chain/data block
The values $TC_CARR1 to $TC_CARR20 and $TC_CARR24 to $TC_CARR33 in the
toolholder data block are of NC language format type REAL..
The values $TC_CARR21 and $TC_CARR22 for the axis name of the first rotary axis (v
the second rotary axis (v
The value $TC_CARR23 is initialized with the uppercase letter "T" (only tool can be rotated).
$TC_CARRn[m]
$TC_CARR[0]= 0 has a special significance
