W1: Tool offset
18.14 Supplementary conditions
A frame rotation of Z through 60 degrees is now programmed with G17 active, e.g. rot Z60.
The direction of the applicate (Z direction) remains unchanged; the main component of L2 now
lies in the direction of the new X axis; the main component of L1 now lies in the direction of
the negative Y axis. The return axis is thus 1, and _AXIND contains the values (2, -3, 1).
In this case, the associated matrix _MATRIX is:

Flat D number structure
Grinding tools
Grinding tools (tool types 400-499) cannot be defined using the simple tool management
structure (flat D numbers).
Block search
T number output to PLC triggers a synchronization process in the NCK: with absolute, indirect
D programming, the PLC returns the D values via NC/PLC interfaces. The NCK waits until the
output of a T number is followed by a response from the PLC: "I have written the D number".
With block search without calculation, this process of synchronization must be deactivated
until the first valid T number has been output again. That means that the NCK must not wait
on D programming.
Note
At what point the auxiliary functions can be output to PLC after block search is complete, can
be controlled with the machine data:
$MC_AUXFU_AT_BLOCK_SEARCH_END (auxiliary function output after block search)
Automatic on end or on NC start.
