’ 3.12 Input for electronic handwheel-servos
3.12.1 Input for electronic handwheel HR 150 or HR 250
For hand-assisted servo, a separate connector input is provided in addition to the transducer inputs. The
electronic handwheel may be connected to this input via a cable of max. 20 m. In the
ELECTRONIC HANDWHEEL mode both the handwheel and the external direction buttons are active.
Pre-selection of the axis to be moved is via the axis-keys X, Y, Z or IV. Pre-selection of traversing range /R.P.M.
of handwheel is via input of factors 1 - 10. Depending on the rapid traverses programmed in the machine
parameters, the factors for fast traverse can be inhibited.

3.12.2 Input for dual handwheel unit HE 310
A separate input is provided for this handwheel unit. The portable unit incorporates two handwheels with
axis selection buttons and emergency stop button. Simultaneous movement of the machine axes X-Y, X-Z,
Y-IV or IV-Z is possible.
A terminal block is located adjacent to the flange input socket for the handwheel unit HE 310 on the rear of
the unit. To activate the “EMERGENCY STOP” of the handwheel unit, the external “EMERGENCY STOP”-
circuit must be connected via terminals 1 and 2.
3.13 Input for touch probe systems
The control versions TNC 151/TNC 155 are eq.jipped with an input for the 3D-touch probe systems
HEIDENHAIN 510 (triggering touch probe for infra-red transmission) or HEIDENHAIN 110 (triggering touch
probe for cable transmission).
Touch probe system 110 comprises a touch probe TS 110 and adapter electronics unit APE 110. The touch
probe system 510 consists of an (infra-red) touch probe TS 510 and a transmitter/receiver unit with adapter
electronics unit APE 510 (dimensions and cable lengths, see operating manual,TS 110, TS 510).
Both touch probe systems are used for automatic datum finding and electronic alignment of workpieces.
If the touch probe is to be used on machines with automatic toolchanger, the touch probe system 510 should
be used. Either system may be used on machines with manually-operated toolchanger.
