15 Tool Changer
A tool changer can be operated with the PLC of the HEIDENHAIN contouring control. Tool changers
are often controlled by proximity switches.
Tool data are stored in the tool table and tool management (special tool, tool pocket management
etc.) is handled by the NC. The NC supplies the PLC with the information it needs to control the tool
changer via markers and words.
15.1 Tool table
The operator can edit the tool table (program 0) in the "Programming and editing" mode (see User's
Manual). The tool table can be uploaded and downloaded through the data interface. The tool
number (T), length (L), radius (R), pocket number (P), and special tool (ST) are all defined in the tool
table. Special tools and pocket number are only displayed if MP7266 and MP7480 have been set
accordingly. The pocket numbers can be protected from editing or erasure by setting marker M2594.

The number of tools in the tool table is defined in machine parameter MP7260. If MP7260 contains
a zero value, then the system will run without a tool table (program "0" does not exist). Tool length
and tool radius are programmed in the NC program with TOOL DEF (see User's Manual).
