Energy t ransmiss ion
Energy transmission
Comparison - E/D transformer
▪ The new 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).
E/D transformer – energy transmission
▪ Two transmission leads are needed to transmit the
energy supply:
P24V (1) and GND (2).
▪ Another lead (sliding contact) connects the rotating
part and the housing ground (ESD protection (3)).

Holding Circuit
Holding Circuit
Venturi block
▪ The venturi block consists of 20 small venturi nozzles
is located behind the silencer.
▪ Each venturi nozzle supplies one segment with
vacuum in the hold circuit.
▪ If a segment is in the pickup/placement circuit, the
holding circuit vacuum is increased (for pickup) or
eliminated via air blast (for placement).

DP drive
7.2.3.6 DP drive
DP Drive - F unction
DP Drive - Function
Measurement System with Hall Sensors – Function:
▪ The sensor detects the movement of ferromagnetic material (toothed wheel) through changes to the
magnetic flow.
▪ If one element is opposite a ferromagnetic tooth and another opposite a gap, this causes a one-sided
increase in induction.
▪ The difference arising between the two elements alters the polarity once the toothed wheel moves.
▪ This change is evaluated, digitized and used to address or give feedback in closed-loop control.
DP axis
The DP axis is responsible for turning the component into
the correct placement position within a set time. Vacuum
and air blast to the nozzle are provided via the hollow
shaft of the DP axis.
The complete DP drive can be replaced during service
work.

▪ 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.
