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 VDC 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.
