5.2.2.5 Star Carrier
1. Index screw for positioning the ED
transmitter
2. Collector ring, supplies the DP drives with
power and data (data is transmitted
contactless)
3. DP drive control board
4. Brackets for mounting the DP control
board
5. DP drives
●
The DP control board is plugged into the motherboard.
●
The motherboard is located behind the DP control boards and supplies the data for
positioning and controlling.
●
Two screws fix the complete DP drive unit from the inside to the star frame.
Note: The Star carrier is not spare part.
5.2.2.6 Star Motor
1. Compressed air connection for hold circuit
2. Incremental measurement system *
3. 3-phasen drive with a voltage of 150V
4. Flange on the motor shaft
5. Connection for measurement of vacuum/
air kiss in the pickup/placement circuit
6. Connection for measurement of vacuum in
the holding circuit
*C&P20 M2 Head: New star with high resolution
●
The star motor is a brushless three-phase drive with integrated measurement system.
●
The motor shaft has a hollow design. This enables vacuum or compressed air to be supplied
to the hold circuit of the 20 segments.
●
The star motor is not a spare part.
1. Smoothed distributor disc
2. Connection for measurement of vacuum/
air kiss in the pickup/placement circuit
3. Connection for measurement of vacuum in
the holding circuit

5.2.2.7 DP Drive
1. Control board for DP Motor
2. Motor
3. New non-transparent switching disk, can’t
be changed anymore
4. Nozzle interface
5. New nozzle type 4xxx with new nozzle
interface
6. Filter disc
7. Linear guide
8. Measurement system *
9. Vacuum / Air Kiss connection
*C&P20 M2: New DP drive with more accuracy
●
The DP drive is responsible for turning the nozzles into the correct pickup position and the
component into the correct placement angle.
●
Vacuum and air blast to the nozzle are provided via the motor shaft of the DP Axis.
●
The complete DP drive with linear guidance can be replaced during service work.
5.2.2.8 Star
1. Motor shaft
2. Grinding disc
3. Star assembly
4. Screws mounting the star unit to the motor
shaft
●
The star consists of the star frame on which all 20 DP drives are mounted, the motherboard
and the collector ring.
●
This complete unit is fixed to the motor shaft with three screws.
Note: The Star is not a spare part.

5.2.2.9 Pressure Control Valve (PRV)
1. Energy and data supply
2. Compressed air connection
3. Vacuum/air kiss for pickup/placement
circuit
4. Discharged air for cooling the X linear
motor
5. Mounting for pressure control valve
●
The PRV supplies the pickup/placement circuit with vacuum during the pickup process and
switches over to air kiss during placement.
●
The valve can be replaced during service work.
●
Sensitivity against dirt and dust is reduced.
NOTICE
The PRV introduced with the C&P20 P is not to be cleaned. Otherwise the built in
protection membrane can be damaged.
