Siemens SINUMERIK 828D Function Manual page 1501

Kinematic type:
$TC_CARR23 using letter T, P or M
The following three options are available for the kinematic type, for which both upper and lower case text are
permissible:
T: Only the (Tool) can be rotated (basic value).
P: Only the workpiece (Part) can be rotated.
M: Both tool and workpiece can be rotated (Mixed mode).
Any character other than the three mentioned here will result in the alarm if it is tried to activate the toolholder
with orientation capability:
Alarm "14153 Channel %1 block %2 unknown tool carrier type: %3"
Rotary axis parameters:
$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 identifier of the first rotary axis (v
rotary axis (v ) are of NC language format type AXIS. They are all preset to zero.
2
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
System variables for toolholders with orientation capability
$TC_CARRn[m]
n: Parameters 1...33
m: Number of the tool carrier 1 that can be oriented...Value of the machine data:
MD18088 $MN_MM_NUM_TOOL_CARRIER (Maximum number of definable tool
carriers)
