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.

7.7 SMPS diagnostic
The diagnostics function in the station software provides easy monitoring of the machine voltage
status.
The following analysis and monitoring options are possible:
●
Monitoring of power pack PS1 and capacitor battery CAP
●
Monitoring of safety states on the CSB
●
Monitoring of intermediate circuit voltages placement heads 160VDC on the FD
●
Monitoring of voltages 42VDC / 28VDC / 24VDC on the FD
For monitoring the power pack voltages and the fuses on the CAP & FD above, there are also two
additional diagnostics circuits within the SMPS, these two diagnostics circuits are combined on the
IOCU and transferred to the station computer from there.
The connections 1, 2 and 3 are used only to pass on diagnostics data and are therefore essential if
the diagnostics function is to work properly.
●
In order for the diagnostics GUI to function properly, the SMPS cables must be connected cor-
rectly. In case of troubleshooting ensure that all cables are connected correctly. If machine
controller does not receive any diagnostics data for the capacitor battery (e.g. malfunction or
missing cable connection), no diagnostics information will be shown for the FD also!
The Diagnostics Master is a fixed part integrated in the CAP1; it evaluates the information from the
entire PS1-CAP1 assembly as needed for diagnostics.
In addition, the data from the CAP1 capacitor battery (charging status, temperature, backup stor-
age capacity, working time) are queried by the Diagnostics Master.
FD.A1 collects all diagnostics data for the low voltage monitoring (from PS2/PS3/PS4 / fuses on
FD) and safety logic (from CSB). The diagnostics data is then sent from the FD to the IOCU.
The information about the 160VDC is also queried for the intermediate circuit voltage of the place-
ment heads. This takes place via the logic on fuses F19 and F20.
7.8 Safety control
Safety control of output voltages is provided by unit CSB (Contactor based Safety Breaker), which
consists of two functional units:
1. Circuit Safety Contact Breaker Unit
2. Pre/discharge board –A2, for monitoring and suppressing the load current of the main axes.
The unit provides functionality for,
