5.3.2.2 Initialize Valve Drive at DP-station

At the DP station, the stepping motor is used to

approach the sleeves (eccentric movement) and

rotate the CO/nozzles into the correct position, via

the DP axis.

Legend:

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.

5.3.5 Reference run at star-axis

The Z-axis runs to uppermost end stop. When

stand still is detected the Z-axis runs down by 30

digits with reduced force. This Z-axis position with

reduced force enables the placement star to move

into reference position.

The star-axis turns counter clockwise to zero point

pulse of the incremental shaft encoder. The zero

point correction is loaded. The star-axis turns

clockwise (according the zero point correction)

until the position counter shows 0 digit.

Segment 1 is now in the pickup/placement

position.
