Footnotes
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.
6) M6: Value range of the address extension:
- without tool management: 0 – 99
- with tool management: 0 – maximum spindle number
0: replace by the value of the master spindle number or the master tool holder
7) If tool management is active, the auxiliary function M6 "Tool change" can only be
programmed once in a part program block, irrespective the address extensions that
are programmed.
8) Maximum number of auxiliary functions per part program block.
