HEIDENHAIN TNC lSl/TNC 155 with SPINDLE ORIENTATION option
.Spindle orientation is available as an option and necessitates an extension of TNC-hardware.
The NC-software for spindle orientation, i.e. for the fifth axis is contained in every TNC 151 B/TNC 155 B.
Installation hints for VDU-units
(Control versions TNC 151 permit the installation of the VDU-unit BE 111 (9 inch screen) or BE 211
(12 inch screen). TNC 155~versions require the VDU-unit BE 411 (12 inch graphic display screen).
When installing VDU-units, it should noted that these units are sensitive to magnetic fields. The hold and
geometry o-f the screen picture can be distorted by magnetic cross-talk.
In the case cof alternating current fields, these can cause periodical picture displacement or picture
distortion with the beat frequency from the picture and the mains frequency.
For this reason, permanent magnets, motors, transformers, magnetic switches and similar should not be
located in the immediate vicinity of the VDU. As an approximation, we recommend a minimum distance
of 0.5 m between the source of interference and the VDU-housing.
In order to maintain a substantial distance between the VDU and the control unit (TNC), we recommend
that the TNC only be mounted to the right or beneath the VDU.
2. Combined technical specifications for TNC 15l/TNC 155
All TNC 151/TNC 155 inputs and outputs may only be connected to electric circuits with protective low
voltage.
Mains power supply

Selectable 100/120/l 40/200/220/240 V + 10 %/ - 15 %, 48 . 62 Hz
If -the permissible mains voltage tolerances cannot be held, we recommend
a voltage regulator type “Voltkraft” which1 is available from Messrs. Conrad
Electronic. The regulator can also be purchased from the HEIDENHAIN
Service Department.
