15 Tool changer
A tool changer can be operated with the PLC of the HEIDENHAIN contouring control. If the tool
changer is to have servo-controlled axes this must be done using a positioning module (see chapter
"Positioning Module"). However it is possible to control a tool changer by simple proximity switches.
Tool data are stored in the tool table and complete tool management (replacement tool, tool life 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, Pocket table
The operator is able to edit the tool table in the "Program run" mode.
The tool table is called with the "TOOL TABLE" soft key. From here the operator calls the pocket

pocket table with the EXT key.
