7.6.2.1 Power Supply(SMPS) – Safety Indication
Lamp indication on PS1
●
LED Green 300VDC to 220VDC
●
LED Red 220VDC to 5VDC
●
LEDS Off less than 5VDC
WARNING
Only after the voltage dropped <5VDC (both LED lamps off) can you work on the power
supply unit without hazard!
Lamp indication on CAP1
●
LED Red greater than 5VDC
●
LED Off less than 5VDC
WARNING
Only after the voltage dropped <5VDC (LED lamp off) can you work on the CAP1 unit
without hazard!
WARNING
The LED status do not grantee that the units are free from voltage it is always necessary to
measure the voltage before commencing service work.
WARNING!

7.6.3 CAP1 - Capacitor Battery (Backup Capacitor)
1. Residual voltage LED (ON > 5V → Haz-
ard!)
2. Input DC IN 300V/160V from power pack
PS1
3. Output DC power out 300V/160V to CSP
4. Diagnostics cable (information diagnostic 1
from PS1)
5. Diagnostics cable LAN to distribution-
board
During braking of the main axes, the capacitor battery CAP1 is charged. This occurs as a result of
the excess energy (generative principle) during braking of the main axes.
●
In the state "emergency STOP" a connection (60ms) to the main axes remains, so that the
braking energy can be discharged.
●
This time delay is controlled by the CSB assembly.
●
In the event of an "emergency STOP/cover open" the capacitor battery will remain energized.
DANGER
The CAP1 assembly – capacitor battery may never be opened!
Risk of electrical shock with lethal voltages
Very important:
Please make sure that the CAP1 assembly is connected to the machine main ground point (MGP).
7.6.4 Power Pack PS2-PS3 and PS4
The power pack PS2/PS3/PS4 is supplied with a mains voltage of 3 x 400VAC (range
360V-440VAC) and provides between 24-42V DC.
1. The output voltage can be adjusted using
the potentiometer behind the white cover.
2. The output voltage can be measured at
terminal Plus+ and Minus-.
3. The input voltage can be measured using
the terminal L1/L2/L3.
The required output voltages are:
PS2 42VDC (+- 500mv)
PS3 28VDC (+- 200mv)
PS3 24VDC (+- 200mv)
Incorrect voltage settings may lead to machine malfunction. It is recommended to check the output
voltages after part exchange, also to avoid damage measure output before connecting output
cables.

7.6.5 Power Supply (SMPS) - Measuring & Testing 300VDC
NOTICE
Before measuring, please read the service manual.
●
The 300VDC from PS1 (IN) can be measured between X303 (300VDC) and X305 (GND).
●
The 300VDC from the CAP1 (OUT) can be measured between X304 (300VDC) and X305
(GND).
1. Measure socket X303
2. Measure socket X304
3. Measure socket X305
NOTICE
Measurement is always performed at the reference point X305 (GND)!
The measurement should be performed using a suitable mains voltage tester as we are
dealing with 300VDC.
Make sure that you do not touch the measuring tips of the measuring devices under any cir-
cumstances.
