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.
