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) is activated at the DC/DC converter to main power supply distributor
X13 to axis unit X21 and to Anti-Crash board.
Here it is split in 2 paths:
path1: 24 V is activated as the
’servo enable signal’ at anti crash board and at the servo board
X/Y axis (via X31, X32, X33, X34) to enable the servo amplifier (switching GND to the servo board
via optical coupler).
path 2: 24 V is activated as the ’
Ctrl_On’ signal at section 2, connector X4qa and at last at 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 activate
at distributor main power supply, connector X16. Then at section 2, main distributor, connector
X2qa and then at the terminal block X1qa for general use, at connector X71qa and at last at
connector X71ra, section 4.
52 V for camera illumination, generated by U7, is activated at main power supply distributor, X18,
and split into two paths.
path 1: at X18, at section 2, X3qa, at terminal strip X1qa and then 52V is activated at the DC/DC
converter vision for converting the 42 V needed for the IC/FC camera illumination. 52V is also
activated at connector X71qa and connector X71ra in section 4, at X1ra and at last at the DC/DC
distributor vision (42V are not used here)
path 2: (this path is presently not shown in overview and not used) 52V is activated at X18 main
power supply distributor, at section 4, X3ra, at terminal strip X1ra and 52V is also activated at the
DC/DC distributor vision for converting 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 +/-15V is activated at X4qa and
terminal block X1qa to get distributed for general use. +/-15V is activated at connector X74qa and
X74ra in section 4, sub-distributor (not shown in overview ’power distribution’)
