6. DP drive
The star carrier plate is fixed directly to the rotor of
the star motor.
The valve terminal and the E/D transformer are
fixed to the back of the star carrier.
The twelve DP drives are fixed to the front and the
holding circuit with control unit (SCS) is fixed to the
center.
The vacuum or air blast is fed via the holding
circuit through the star carrier plate to the
individual DP drives (through a hose).

4. Connector for data and power supply to the DP
drives
The SCS has two main tasks:
1. Controlling the DP drives
2. Evaluating the Z down light barrier.
The assembly consists of a carrier plate and two
boards (control module and power module).
The power and data supply is via the head CAN
bus from the intermediate distributor, E/D
transformer to the SCS.
The SCS features 12 connectors, which establish
the connection for the power and data supply to
the DP drives.
The SCS can be replaced during service work.

8.2.7.10 Valve terminal
The valve terminal consists of 12 valves (1), one for each segment.
The compressed air from the holding circuit (2) is distributed over 12 channels for the 12 segments. Each
of these channels has a valve. This enables the compressed air to be connected or disconnected for
each segment (3).
This means, After a component has been placed, the compressed air can be disconnected for this
segment.
Before picking up a component, the compressed air is connected again and vacuum is present at the
nozzle via the holding circuit with venturi nozzles. The disconnection of compressed air after placement
reduces the compressed air per placement head by approx. 40-50%.
The outer channels (4) are used to measure the holding circuit and supply the air blast or vacuum for the
pickup/placement circuit via the pressure control valve.
The valve terminal can be replaced during service work.

6. Flexprint for energy and data transfer to SCS
The valve terminal consists of 12 holding
circuit valves, which can be switched
independently at any time and in any star
position.
Switching on the valves means “throughput”:
Compressed air is present at the venturi
nozzles (voltage = 0V). If a valve should fail or
if it is without a voltage supply, vacuum is
always present at the holding circuit.
Switching off the valves means “valve closed”:
There is no compressed air present at the
venturi nozzle (24 V voltage is present). This
saves compressed air!

8.2.7.11 E/D Transformer
The energy and data transformer consists of a stationary and a rotating part.
The three sliding contacts transmit the direct current voltage (24V/4A).
Communication (the transmission of CAN Bus signals) is contactless. The transmitter is located on
the rear cover of the CPP head and the receiver module on the valve terminal.
The connector (4) supplies power and data to the intermediate distributor.
The centering pin fixes the stationary part in place via the rear cover of the CPP head.
The rotating part is fixed with five screws to the valve terminal.
The E/D transformer can be replaced during service work.
Energy transmission
Two transmission leads are needed to transmit the energy supply: P24V (1) and GND (2).
Another lead (3) (sliding contact) forms the connection between the rotating part and the housing
ground (ESD protection).
