6.2.1.1 Initialize Valve Drive at Pick-up / Placement Position / Reject Position
The function of the stepper motor, with the aid of an eccentric movement, is to move the plunger
which will switch vacuum on and allow component to be picked. When placing the component the
plunger is switch again for nozzle closed, so that we have air kiss on the nozzle for placement.
When reject the component the plunger will switch air kiss on and allow component to be rejected.
After this we switch back on vacuum .
Fig. 6.2 - 2 Initialize valve drive at pick-up / placement / reject position
Key:
1. Home position, initial position. Give way free for Star axis movement. Drawing show 2 possible
positions of the plunger
2. 2a. is switching to vacuum, Vacuum value "Nozzle open"
2b. is switching to air kiss, Vacuum value "Nozzle closed"
3. Counter position to initial position. Give way free for Star axis movement.
– The stepper motor of the valve drive is turned to the home position. The stepper motor runs
and the light barrier on the cam disk sets the end signal.
– Because of the special shape of the cam disk the stepper motor is able to recognize the home
position (1.).

6.2.1.2 Initialize Valve Drive at DP-station
The function of the stepper motor at the DP station, with the aid of an eccentric movement, is to
contact the sleeve and rotate the components and nozzles to the correct position via the DP axis.
Fig. 6.2 - 3 Initialize stepper motor at DP-station
Key
(1) Home position DP drive around 1 mm away from segment
(2) Engaged position DP drive at segment
– The stepper motor of the valve drive is turned to the home position. The stepper motor runs
and the light barrier on the cam disk sets the end signal.
– Because of the special shape of the cam disk the stepper motor is able to recognize the home
position.
