7.3 Reference Run for C&P20A Head
7-8: Reference run for C&P20 head
The C&P20 head has 22 axes: the Z axis, the star
axis and 20 independently working DP axes, plus
the X and Y axes for the gantry. Before starting
production, all axes must be initialized, so that the
axis controller can locate their actual mechanical
positions. The software start procedure first loads
the DP master firmware and then rotates the DP
axes into the 0° position.
General Procedure
The reference run for the individual axes can
be optimized so that the X, Y, star and all DP
axes visibly start at the same time. As can be
seen in the flow chart, only the Z axis is moved
as the last axis.

7.3.2 Star Axis Reference Run
7-9: Preparing the Z axis reference run (C&P20A)
The Z axis return unit ensures that the Z axis is in
a safe position (Z up) as soon as the machine is
started. This is the requirement for starting the star
axis reference run.
7-10: Star axis reference run
The star axis rotates in an anticlockwise direction
(1) to the zero pulse of the incremental encoder.
After reaching the zero pulse, the zero point
correction is loaded. The star axis rotates in a
clockwise direction (2) (according to the zero point
correction factor) until the zero point correction
position is reached and then sets the counter to 0
digits.
Segment number 1 is now in pickup / placement
position.
