Starting the tool change

The tool change can be actuated by:

● T function

● M command (preferably M06).

Parameter setting

Which control versions should be effective is defined with the machine data:

MD22550 $MC_TOOL_CHANGE_MODE

The M command for tool change is defined in machine data:

MD22560 $MC_TOOL_CHANGE_M_CODE

Default setting is 6 (corresponding to DIN 66025).

If the tool offset number is supplied from the PLC or an HMI tool manager, a block search

stop STOPRE must be inserted at a suitable point. STOPRE must be avoided, however, when

tool radius compensation (G41 / G42) or SPLINE interpolation are active, since several

blocks are required here in advance for the path calculation.

You will find further information about M functions which also apply to tool change M06 (e.g.

extended address, time of output to PLC, auxiliary function groups, behavior during block

search, behavior during overstore) in:
