17 Power Supply
17.1 Power Supply for the iTNC 530
17.1.1 Introduction
The iTNC 530 is powered by ...
The CC 42x is powered via the 50-pin ribbon cable connection and additionally via a 5 V terminal,
if required.
The CC 42x in turn powers the connected MC 42x (B/C) via a connecting board with connector.
When using the UV 106 (B), the CC is not required. --> The MC is directly connected to the
UV 106 (B).
This makes it possible to operate analog axes and spindles exclusively.
Pin layout --> See "Power Supply Units" on page 27 – 487.

Note
The iTNC 530 (MC/CC) powers the connected units, such as scales, motor encoders, touch
probes, handwheel, transmitter-receiver units.
Exceptions:
The screen has its own connection for power supply.
The PLC outputs are powered with 24 V machine voltage.
Infra-red touch probes have a battery.
Damaged units that are powered by the iTNC may affect the supply voltages and thus the
entire system.
Note
The central voltage for powering the electronics is the 5 V supply voltage.
The control monitors this 5 V supply voltage.
If it falls below 4.75 V, the error message 5-V power supply too low is displayed.
If it rises above 5.40 V, the error message 5-V power supply too high is displayed.
