Tool lengths L1, L2, L3 assignment: LENTOAX

LENTOAX function
The "LENTOAX" function provides information about the assignment of tool lengths L1, L2
and L3 of the active tool to the abscissa, ordinate and applicate. The assignment of
abscissa, ordinate and applicate to the geometry axes is affected by frames and the active
plane (G17 - G19).
Only the geometry component of a tool ($TC_DP3[x,y] to $TC_DP5[x,y]) is considered, i.e., a
different axis assignment for other components (e.g., wear) has no effect on the result.
The "LENTOAX" function is a predefined subprogram. It must, therefore, be programmed in
a separate block.

Value/parameter:
Status
_AXIND[3]
Basic logic functions: Tool Offset (W1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Status = LENTOAX(_AXIND, _MATRIX, _COORD)
The first two parameters must always be programmed; the last parameter can be
omitted.
INT
0: Function OK, information in _AXIND sufficient for description (all tool length
components are parallel to the geometry axes).
1: Function is OK, however, the content of _MATRIX must be evaluated for a correct
description (the tool length components are not parallel to the geometry axes).
-1: Invalid string in parameter _COORD.
-2: No tool active.
INT
Indices 0 to 2 are assigned to the abscissa (0), ordinate (1) and applicate (2) (e.g.,
_AXIND[0] contains the number of the tool length components, which are effective in
the direction of the abscissa).
The content has the following significance:
0: Assignment exists (axis does not exist)
1 to 3: Number of the length effective in the corresponding coordinate axis. The
or sign is negative if the tool length component is pointing in the negative
-1 to -3: coordinate direction.
