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 MD 22110: 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 full precision. 
4)  If the setting is MD22110 $MC_AUXFU_H_TYPE_INT = 1, the REAL values are rounded 
before output to the PLC. 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 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.
