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:
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.
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
1
) and the second
rotary axis (v
2
) are of NC language format type AXIS. They are all preset to zero.
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]
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).
Note
The system variables are available with and without active tool management.
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)
