3.1  3.1 General constraints 
Spindle replacement 
Because the auxiliary functions are parameterized channel-specifically, if function: "Spindle 
replacement" is used, the spindle-specific auxiliary function must be parameterized 
immediately in all channels that use the spindles. 
Tool management 
If tool management is active, the following constraints apply: 
•  T and M<k> functions are not output to the PLC.  
Note 
k is the parameterized value of the auxiliary function for the tool change (default: 6): 
MD22560 $MC_TOOL_CHANGE_M_CODE (auxiliary function for tool change)  
•  If no address extension is programmed, the auxiliary function refers to the master spindle 
or the master tool holder of the channel. 
Definition of the master spindle: 
– MD20090 $MC_SPIND_DEF_MASTER_SPIND 
– Part program instruction: SETMS 
Definition of the master tool holder 
– MD20124 $MC_TOOL_MANAGEMENT_TOOLHOLDER 
– Part program instruction: SETMTH 
Maximum number of auxiliary functions per part program block 
A maximum of 10 auxiliary functions may be programmed in one part program block.  
DL (additive tool offset) 
The following restrictions apply to the DL function: 
•  Only one DL function can be programmed per part program block. 
•  If DL functions are used in synchronous actions, parameter: "Value" is not output to the 
PLC.
