5.1.2 Main Parts/Unit Overview
5.1.2.1 Star
1. Single Core Solution (SCS)
2. Holding circuit in center of star
3. DP drives
4. ED transmitter 24V (contactless energy
transfer)
5. Fixture on rotor of star motor
6. Valve terminal/board
7. Star frame
●
The star consists of the star frame, on which the 12 DP drives are located, the control board
(Single Core Solution), the valve terminal and the E/D transmitter.
●
The holding circuit is in the center of the star.

1. Lubricate position Star bearing
2. Stator Star Motor
3. Rotor Star Motor / Interface for fixing the
star frame
B Interior View
4. Reader head measuring system
5. Incremental measuring system
●
The motor functions contact free i.e. there is no wear and tear.
●
The head casing also serves as the motor casing.
●
The star motor is not a spare part and can not be replaced.

5.1.2.2 DP Drive
1. Vacuum / Air kiss connection
2. Motor
3. The connector screwed to the SCS control
unit
4. Nozzle interface
5. Camera background (black) for DP drive
6. Mounting surface for screwing the linear
guide
7. Measuring system
●
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 can be replaced during service work.

2. Cushioning path for operating the light
barrier down
3. Light barrier down
DP Drive function
●
The DP drives are controlled by the SCS board, in accordance with the counter pulse and
nominal value (pickup angle, placement angle and correction angle after Vision).
●
The feedback about the position of the DC motor is monitored by an incremental measuring
system.
Light barrier bottom
●
Each DP drive has its own light barrier down sensor. When the Z Axis springs into place, the
sensor sends a signal to the axis controller board (MHCU).
●
The "light barrier down" signal is directly linked to the measurement signal of the Z Axis
incremental encoder.
