9.2 Digitizing with TS 120
Digitizing is possible with all HEIDENHAIN triggering touch probes. However, because the digitizing
process can take several hours to complete, it is advisable to use the TS 120 touch probe with signal
transmission by cable. The TS 511 touch probe with its infrared signal transmission can be
continuously operated for up to 8 hours on one battery charge.

Technical Requirements

- "Digitizing with TS 120" is possible with TNC 415 using software types 259 96 and 259 97 and
with TNC 407 using type 243 02 (see also the section "Software" in the chapter headed
"Introduction", ).
- Installing the software module "Digitizing with the TS 120". The ID. number of the logic unit
indicates whether the software module is already installed (see the section "EPROM Locations" in
the chapter headed "Introduction", and the section "Hardware Components" in the chapter
"Installation and Electrical Connection").
If the module is already installed, the software number of the option will appear beneath the NC
and PLC software number, when the system is switched on or when the MOD key is pressed.
- Interfaced touch probe TS 120.
- The machine must be optimized for "Trailing error operation".
The digitizing sequence is optimized by the machine parameters.
Machine parameter MP6210 is the value for the oscillations executed by the touch probe as it scans
the form. It is governed by the dynamic response of the machine.
The dynamic response is in turn determined by the Kv factor (trailing error operation). The greater
the Kv factor, the greater the number of oscillations.
Machine parameter MP6210 determines the maximum probing feed rate in conjunction with the
programmed probe point interval, PP.INT from the scanning cycles "Meander" and "Contour Lines":
F[mm/min] = PP.INT [mm] x oscillations [1/s] x 60 [s/min]
This relation gives the formula for calculating the input value of MP6210:
optimized F [mm / min]
Oscillations [1/s] =
PP.INT [mm] x 60 [s / min]

The optimized probing feed rate depends on the feed rate in the normal direction (MP6230).
