4.2.5 Power Supply Computer Unit
When the main switch is on, the DC/DC converter in the computer unit is supplied with 52 VDC
by the main power supply unit. The following voltages are then generated in the control unit:
4
+ 3.3 VDC / 6A to supply the CPU of Machine Controller and CPU of Station Computer. 4
+ 5 VDC / 6A to supply the digital electronic circuits. 4
± 12 VDC to supply the digital electronic circuits. 4
± 15 VDC (not used, LED off) 4

4.2.6 Power Supply Axis Unit
When the main switch is on, the axis unit is supplied with 52 V from main power supply via X13
and generates the voltages as shown below.
The +-15V and 5V supply voltages for the servo unit’s electronic circuits are generated from the
two DC/DC converter, which are integrated in the servo unit. This DC/DC converter generates the
5V and +- 15V needed for the servo board and the axis controller and the +-15V are also used on
placement heads and anti-crash, for e.g. It will travel to main distributor X4qa (sector 2) and then
to terminal block X1qa and get distributed from here.
