9 Short circuit/probing
The TNC normally uses input X12 as the short-circuit input (see also section "Short circuit, CYCL
STOP and arcing"). If the TNC probing functions are to be utilized, either the electrode or a probe
system from HEIDENHAIN (such as the TS 120) can be used to perform the probing.
Marker M2028 indicates whether the control is currently in one of the probing functions, for
example so that a test voltage can be turned on between the electrode and the workpiece.
The chapter "Installation and electrical connection" contains instructions for connecting the short
circuit input X12.
9.1 Interfacing the probing function
If the probing function is used (such as the TS 120 touch probe), the machine tool manufacturer
must ensure that the rotary axis, if present, cannot turn when the touch probe is in use.
The probing functions can be controlled either with the probing cycles in the "Manual" and "Electronic
Handwheel" modes or by the "Touch Probe" function in the NC program (see TNC User's Manual).
The probing function is interfaced to the measuring conditions using machine parameters MP6120
to MP6150.
