8.2 Reference Run
The C&P20 head has 3 axis types: the Z-axis, Star axis and DP axes, pluse 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 sequence 8
– With a few exceptions, this reference run principle is the same as that of the DLM2 6 and 12
nozzle C&P heads. However, stepping motors are no longer to initialize, as the C&P20 head
is equipped with a pressure control valve for vacuum and air kiss and each segment has its
own DP drive. For this reason, the functions previously performed by the stepping motor are
now redundant.
– In Siplace X machines, all heads C&P head, TWIN head make the reference run at the same
time, the gantry axes follows.

Rejects component with cleaning pulse
for all segments, if necessary
The X/Y axes move the head to the fixed conveyor side
Nozzle height and closed vacuum is measured for
all segments.
