See "Meaning of footnotes" at the end of the overview.
1) If tool management is active, neither a T change signal nor a T word is output to the
interface (channel).
2) The type for the values can be selected by the user via MD22110
$MC_AUXFU_H_TYPE_INT.
3) Because of the limited display options on the operator panel screens, the REAL type
values displayed are restricted to:
–999 999 999.9999 to 999 999 999.9999
The NC calculates internally but with complete accuracy.
4) The REAL values are rounded and output to the PLC when setting the machine data:
MD22110 $MC_AUXFU_H_TYPE_INT = 1 (type of H-auxiliary functions is an integer)
The PLC user program must interpret the value transferred according to the machine
data setting.
5) If the tool management is active, the meaning of the address extension can be
parameterized. Address extension = 0 means the value must be replaced by that of the
master spindle number, i.e. it is equivalent to not programming the address extension.
Auxiliary functions M19 "Position spindle" collected during a block search are not output
to the PLC.
