22560 TOOL_CHANGE_M_CODE
MD number M function for tool change
Default setting: 6 Min. input limit: 0 Max. input limit: 9999 9999
Change takes effect after POWER ON Protection level: 2/4 Unit: -
Data type: DWORD Valid as of software version: 1.1
Meaning: If the T function is used only to prepare a new tool for tool change (for milling machines with
tool magazine, this setting is mainly used to bring the new tool to the tool change position in
parallel with the machining time), the tool change must be initiated with a further M function.
The M function entered in the MD initiates the tool change (remove old tool from the spindle
and load the new tool in the spindle). According to DIN 66025, this tool change must be
programmed with the M function M06.

22562 TOOL_CHANGE_ERROR_MODE
MD number Error reaction with programmed tool change
Default setting: 0 Min. input limit: 0 Max. input limit: 3
Change takes effect after POWER ON Protection level: 2/4 Unit: -
Data type: DWORD Valid as of software version: 5.1
Meaning: If MD 22550 is set to 0, the default setting of MD 22562 should not be altered.
Bit0=0: Standard response:
The program stops in the NC block containing the error.
Bit0=1: If the error occurs in the block containing the tool change preparation command,
the alarm activated by the preparation command (T) is ignored until the program
run reaches the point at which the associated tool change command (M06) is
interpreted.
The alarm activated by the preparation command is not output until this moment.
The user cannot therefore make any corrections until this program block is
reached.
Bit1=0: With active tool management only:
In preparing tool changes, the NCK detects only tools with data assigned to a
magazine.
Bit1=1: With active tool management only:
The NCK also loads a tool whose data are stored in the NCK, but to which no
magazine is assigned.
In this case, the NCK attempts to assign the tool data to the programmed spindle
location automatically.
If several usable tools are available, another search is started for an active tool.
If no active tool can be found, the tool with the lowest duplo number is selected.
Bit2=0 Active D no. > 0 and active T no. = 0 equals an offset of zero
Active DL no. > 0 and active D no. = 0 equals a total offset of zero
Bit2=1 Active D no. > 0 and active T no. = 0 generates an alarm message
Active DL no. > 0 and active D no. = 0 generates an alarm message
