$NT_BASE_TOOL_COMP

Function
Using bit-coded system variable $NT_BASE_TOOL_COMP, for each of the geometry axes you
can separately set whether for the base tool an offset is entered in transformation frame
$P_TRAFRAME. This means that when the transformation is selected, no change is made in
the WCS component.
This function is only available if system frame $P_TRAFRAME was configured using MD28082
$MC_MM_SYSTEM_FRAME_MASK bit6.
The system variable is only relevant for TRANSMIT and TRACYL.
Syntax
$NT_BASE_TOOL_COMP[<n>, <m>]
Meaning
$NT_BASE_TOOL_
COMP:
<n>:
<m>:
Example
The 2nd transformation is assigned the name "B axis":
Program code
N100 $NT_BASE_TOOL_COMP[n,0];

Bit-coded system variable
Data type: INT
Default value:
System variable or transformation index
Data type: INT
Value range: 1, 2, ... (MD18866 $MN_MM_NUM_KIN_TRAFOS - 1)
Bits for coding the offset:
● Bit 0 acts in the direction of the X axis (geometry axis 1)
● Bit 1 acts in the direction of the Y axis (geometry axis 2)
● Bit 2 acts in the direction of the Z axis (geometry axis 3)
Data type: INT
Comment
; Transformation "n" is compensated for
in the X-axis direction.
