4.2.10.3 Control On signal
With energizing the contactor K4 of power supply, the auxillary contact of K4.5 (K4) get closed.
24 V (servo enable signal) travel from DC/DC converter to main power supply distributor X13 to
axis unit X21 and to Anti-Crash board.
Here it is split in 2 path:
path1: 24 V travel as the
’servo enable signal’ from anti crash board to the servo board X/Y axis
(via X31, X32, X33, X34) to enable the servo amplifier (switching GND to the servo board via op-
tical coupler).
path 2: 24 V travel as the ’
Ctrl_On’ signal to section 2, connector X4qa and end on the CAN I/O
module as
M_Ctrl_On.
The 4 main axis is allowed to move now into any position.

4.2.11 Power Distribution
The power distrubtion to the different section, gantry and heads is highly structured.
5V and 24 V, generated by DC/DC converter U20 and U30 in main power supply, will first travel
to distributor main power supply, connector X16. From here to section 2, main distributor, connec-
tor X2qa and then to the terminal block X1qa for general use and via connector X71qa to section
4, X71ra.
52 V for camera illumination, generated by U7, will travel to main power supply distributor, X18,
and split into two path.
path 1: from X18 to section 2, X3qa, to clamping field X1qa and travel to DC/DC converter vision
for converting the 42 V needed for the IC/FC camera illumination. It travels then also via connector
X71qa to connector X71ra in section 4, to X1ra to DC/DC distributor vision (42V are not used here)
path 2: (this path is presently not shown in overview and not used) from X18 main power supply
distributor to section 4, X3ra, to clamping field X1ra and travel to DC/DC distributor vision for con-
verting the 42 V needed IC/FC camera illumination in this section.
+-15 V are generated in the power supply axis unit from 52 V and travel from here to X4qa to ter-
minal block X1qa to get distributed for general use. It travel then via connector X74qa to X74ra in
section 4 to sub-distributor (not shown in overview ’power distribution’)
