8.2.2 Preparing the Z-axis Reference Run
Fig. 8.2 - 2 Preparing the Z-axis reference run (C&P20)
The retract unit on the C&P20 head of the Z-axis ensures that the Z-axis is already in a safe po-
sition after the machine has been started up. This means that the star can be rotated properly dur-
ing the reference run, without the need for a prior reference run of the Z-axis.
8.2.3 Star Axis Reference Run
Fig. 8.2 - 3 Star axis reference run
The star axis rotates in an anticlockwise direction (1) to the zero point pulse of the incremental
encoder. After the star axis reach the zero point pulse, the zero point correction factor is loaded
and the star axis rotates in a clockwise direction
(2) (according to the zero point correction factor)
until the position and set the counter to 0 digits.
Segment 1 in now in the pickup/placement position.

8.2.4 Z-Axis Reference Run
Fig. 8.2 - 4 Z-axis reference run
PLEASE NOTE:
Placement software startup initiates a comparison of the head EPROM Z-axis/star axis zero point
correction factor with that of the machine data. If there is variance, SITEST will offer a new cali-
bration of the zero point correction from the Z- and Star Axis, otherwise a normal Z-axis reference
run will begin.
The Z-Axis travels down to the zero point pulse of the incremental encoder. After the Z- Axis find
the zero point pulse, the zero point correction will be loaded. The Z- Axis travels to the zero point
correction value and the position counter is set to 0 digits.
