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 could 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.
Preparing the Z axis before the reference run (C&P20A)
The Z axis retract 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.

▪ The machine start procedure: After the DP master firmware is loaded the DP drives are initialized.
▪ In the reference runs for the star axis, the DP drives rotate the segments into the 0° position again.
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.
Z Axis Reference Run
The Z axis travels down to the zero pulse of the
incremental encoder. After reaching the zero pulse, the
zero point correction is loaded. The Z axis travels to the
zero point correction value and the position counter is set
to 0 digits.
NOTICE! Station software startup initiates a
comparison of the Z and star axis zero point correction
values between the head EPROM and the machine data.
If the zero point correction values are not the same,
recalculate the zero point correction for the Z and star
axes.
DP axis reference run
The DP axis rotates the nozzle into the correct pickup
angle and placement angle. After component recognition
has been performed, the DP axis turns the components
into the correct placement angles and the determined
correction angle from the vision system.

▪ The DP axes can also be referenced independently of the star and Z axes.
▪ By determination of the largest amplitude of the Hall sensor becomes the 0° position of the nozzle in
the factory (mechanically adjusted) and can't be changed.
The C&P head reference run has been successfully completed!

7.3.6 Height Reference Run
With this function we check the correct fitting of the nozzle on the sleeve and that the correct nozzle type
like the programmed one are set to the sleeves. The nozzle length is taken to calculate the pick up and
placement height for the subsequent placements.
Vacuum check procedure
▪ The gantry axes move the C&P head to the reject
position so that the nozzles can be cleaned before
the measuring cycle.
▪ The Star axes move in an anticlockwise direction and
all cleaning functions are performed at the same time,
within one head cycle.
1. The DP drives rotate each segment into the 0°
position.
2. The digital pressure control valve now activates the
air blast for the reject position. The components still
on the nozzle will be rejected.
NOTICE
In SIPLACE SX and X machines, components are rejected vertically downward.
