13. FD (Low voltage fuse distribution)
Function Description
●
The switched mode power packs (multiple AC/DC converters) converts the line voltage to the
individual voltages needed.
●
No conventional power supply transformers are required.
●
Four power packs PS1, PS2, PS3 and PS4 are connected directly to the mains voltage 3 x
400VAC (exception low voltages countries).
The following voltages are generated:
PS1: 300VDC/160VDC
PS2: 42VDC
PS3: 28VDC
PS4: 24VDC
●
The high intermediate circuit voltages of the main axes (300VDC) and head axes (160VDC)
are backed up via the backup battery CAP and backup capacitors to the Fuse and Distribution
board FD assembly and on to the axis control assemblies. (MGCU and MHCU).
●
Voltage of 300VDC from PS1 used to charge capacitor battery in CAP assembly; this backup
battery emits energy to the main axes and also can absorb energy from the main axes.
●
The capacity of power pack PS1 is not enough for main axis acceleration (gantry jump) so en-
ergy is taken from the CAP, during gantry breaking the CAP is recharged, this function of the
backup battery removes the need for a ballast circuit.

7.2 Wiring colour description
There is wire colour code to show voltage level of specific single wires. So you can identify voltage
levels at tested parts using wire colors:
