5.2.2 Main Parts/ Unit Overview
5.2.2.1 Z Axis Drive
1. Mounting for Z Axis
2. Incremental measurement system
3. Primary part of linear motor
4. Secondary part of linear motor
5. Ceramic jaw
6. Light barrier Z-down (analog)
The Z Axis is supplied with 40V/ 3,28A from the MHCU.
The incremental reader head has an EEprom on the connector to store statistic and axis data.
The Z Axis unit and the raceway are complementary parts, it is not possible to change one of
the above mentioned parts.
5.2.2.2 Z Axis
1. Raceway
2. Segment 1
3. DP ball bearing
4. Light barrier Z-down
The Z-drive is not a spare part!
The light barrier Z-down is not a spare
part!
5. Jaw
Functionality of the Z-drive
The ceramic jaw is mounted to the primary part of the Z Motor for mechanical docking of the
DP drives.
The analog Z-down sensor is located at the placement position for recognition of the Z Axis
set down position.
When the Z Axis springs into place, this sensor sends a signal to the axis controller card
(MHCU) The "light barrier down" signal is directly linked to the measurement signal of the
Z Axis incremental encoder.

5.2.2.3 Component Sensor
1. Power/ data supply cable
2. Mounting to housing
3. Laser beam
4. Transmitter and receiver unit with
protected prisms
The component sensor is installed in the
pickup-placement position on the C&P20 P
Head.
The sensor is fixed to the head with two
screws (2).
1. Downwards (A) or upwards (B) movement
2. Nozzle
3. Component
4. Reading out the Z position, if the laser
beam is interrupted (A) or has been
released again (B)
Component Sensor Functions
The component sensor determines the
component and nozzle height during the
placement process.
The component sensor signal is directly
linked to the measurement signal of the Z
Axis incremental encoder for recording the
position.
5.2.2.4 Retract Unit
1. Compressed air connection
2. Solenoid valve
3. Pneumatic cylinder
4. Mounting of retract unit
5. Actuator to move the Z Axis
Retract unit Functions
The retract unit is installed on the Z Axis
and is responsible for protecting the Z Axis
from damage by moving it into a safe
position in the case of unexpected events
e.g. power cuts or machine shutdown.
The retract unit is fixed with two screws
and can be easily replaced during service
work.

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
