TNC 416/TNC 406/TNC 306 Short-circuit signal/Touch probe input 3/99
8 Short-circ uit signal/Touch probe input
This input allows detection of short circuits during the eroding process (see the chapter "Machine
integration", section "Gap control with feed forward control"). In addition, workpieces can be
measured or set up electronically with the manual or programmable probing functions (see the
User's Manual for the TNC 416/TNC 406/TNC 306).
Either electrodes or 3D probe systems TS 220 from HEIDENHAIN can be used for such functions.
For start-up and adjustment of the "Probing" function or of a 3D-touch probe system, see the chapter
"Machine integration."
