Power is supplied through the 50-line ribbon-cable connector X69 and in addition through a 5 V
Power supply by
terminal on the UV 105.
UV 105
The UV xxx does not have an additional 5 V terminal and thus cannot power the iTNC 530
sufficiently. The 50-line ribbon cable X69 of the UV xxx is connected to the UV 105 so that the
status signals of the UV xxx can be transmitted to the iTNC.

Note
When using HEIDENHAIN inverters that are not provided with the additional 5 V terminal on
the front panel (e.g. UE xxx, UE xxx B, UR xxx, UV xxx), normally the UV 105 is required.
In case of a low current consumption of the iTNC 530 (e.g., single processor with low clock
frequency, only few peripheral units are connected) it is possible that the machine
manufacturers have not used the UV 105.
The UV 105 can also be used if the iTNC 530 is combined with non-HEIDENHAIN inverters
to power the HEIDENHAIN control.
Since status signals from non-HEIDENHAIN inverters are not available or are not compatible
to HEIDENHAIN systems, the adapter (ID 349 211-01) is then connected to X69 of the
UV 105.
