7.2.3.5 Star Assembly
Star carrier
The mechanical E/D transformer (1) consists of a stationary and a rotating part. The 6 sliding contacts
transmit direct voltage (24V/4A), ground and CAN bus signals (CAN high, CAN low). The E/D
transformer can be replaced during service work.

shaft
4. Smoothed distributor disc
The star consists of the star carrier, on which the
20 DP drives are located, the motherboard and the
E/D transformer.
This complete unit is fixed to the motor shaft with
three screws and can be removed for service work
after the raceway has been dismounted.
Above the star you will find the E/D
transformer (1) for supplying energy and data
to the DP drives.
The motherboard is located behind the control
boards (2) of the DP drives (3) and is
responsible for controlling and positioning the
DP drives.
The control board is plugged into the
motherboard and is fixed via the two brackets
(4).
Two screws fix the complete DP drive unit from
inside, to the star frame.
An index screw (5) ensures that the ED
transformer is correctly positioned during
assembly.

C&P20A Head – E/D Transformer (Collector Ring)
Energy transmission
7-3: E/D transformer
The E/D transformer consists of a stationary
and a rotating part.
The three sliding contacts (5) transmit the
direct current voltage (24V/4A).
Communication, in other words the
transmission of CAN Bus signals, is
contactless.
Connector (1) (connection to intermediate
distributor)
The centering pin (2) fixes the stationary part
(4) in place.
The rotating part (3) is fixed with five screws to
the star carrier. These can be loosened via the
service opening (6).
7-4: E/D transformer – energy transmission
Two transmission leads are needed to
transmit the energy supply:
P24V (1) and GND (2).
Another lead (sliding contact) forms the
connection between the rotating part and the
housing ground (ESD protection (3)).

7.2.3.6 DP drive
DP Drive - Function
DP axis
The DP axis is responsible for turning the
component into the correct placement position
within a set time. The hollow shaft of the DP axis
provides vacuum and air blast to the nozzle.
The complete DP drive can be replaced during
service work.

7. Filter disk
The DP drives are controlled by the DP
master, in accordance with the counter pulse
and set value (pickup angle, placement angle
and correction angle after Vision).
The DC motor is monitored by a measurement
system attached to the motor axis.
