The mains supply cable is connected to the connection terminals in sector 1 at the output end.
The power supply for TX consists of one assembly, located behind the cover at location 2.
The Power Supply is known as SMPS (Switched Mode Power Supply).
All voltages needed for machine operation are generated by SMPS.
Power supply SMPS components
●
Generation of all supply voltages needed (300V,160V, 42V, 28V, 24V).
●
Distribution and fusing of output voltages.
●
Diagnostic interface for fuse state and power converter diagnosis.
●
Safety control of link voltages (42V, 160V and 300VDC) and signal (24V-S and Power Enable
signal).
●
DC voltage backup for main axes (CAP = capacitor battery buffer), IO and signal distribution.
●
Modular gantry drives servo/control units (MGCU).
●
Machine cable harness interface.
DANGER
The unit contains energy storage components with timed discharge, be careful when work
has to be done at 300V and 160V DC parts of the unit. Wait 5 min before commencing any
work on the SMPS connection or disconnection of units is allowed only in discharged state.
Measure the voltages before commencing any work on SMPS.

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.
