10.3.3 Adjusting the zero points
When certain components of the SIPLACE G are replaced, the machine must be measured again. Partial or
full calibration of the machine may be required. The following overview shows the order and interdependen-
cies of the individual calibration procedures (see Fig. 10.3.1). Important note: Before carrying out any calibra-
tion procedures, always check which procedures are required. For example, the PCB camera must be
calibrated before the offset between the PCB camera and glue application head 3 may be recorded.
PLEASE NOTE
The reference point for all offset calculations is the fixed glue application head 3. The machine can be mea-
sured more quickly if an aluminum test PCB is moved crosswise onto the center conveyor.

10.3.3.1 Zero point correction for the z axes
PLEASE NOTE
The zero point correction for the z axis(es) must be carried out before all other settings. A zero point correc-
tion is always required when the cam disc is released.
● Before the reference run for the z axis, release the cam disc and then clamp it lightly. To do this, loosen the
clamping screw on the hub of the cam disc and then tighten it again manually.
CAUTION
The cam disc must be released before the reference run. In the event of a wiring error (e.g. tacho confused
with motor), the axis can run away at full speed and damage the Z axis carriages. It is also possible for the
zero reference mark to be behind the cam disc, in which case the z axis would lie against the end stop.
● Load the SIKLEBER test program. Please read the warnings at the start of this chapter.
● Connect the axis testing device to the Z axis board. On the axis testing device, select the display for the
corresponding z axis.
● Set the zero point correction for the z axis to a provisional value of 10 digits. To do this, select the "Axes"
menu, followed by "Z axis ...", then "Change axis data", then "Positions" and then "Zero point correction".
● Start a reference run for the z axis by selecting the "Run axis reference" option. Press the Return key to
start the Z axis direct-drive motor running clockwise.
● Switch the z axis off briefly and then on again at the axis board. The motor will then reverse its direction of
rotation and search for the zero pulse. Once it finds the zero pulse, the axis board will set the ACTUAL
position counter to -10 digits (negative zero point correction). The reference point has been reached when
the counter position = 0 (end signal).
● Turn the cam disc counterclockwise as far as the stop (with the nose of the cam disc lying against the top
ball bearing).
● Set the z axis to 680 digits. The cam disc can still be easily clamped.
● Switch off the servo and carefully move the cam disc until the clamping screw on the hub is easily accessi-
ble. Tighten the clamping screw with an Allen key.
● Ensure that the cam disc is aligned centrally with respect to the top and bottom ball bearings.
● If the position of the cam disc on the motor shaft does not change after you tighten the screw, the maxi-
mum travel distance is still 680 digits. Otherwise, enter the precise zero point correction in the machine
data.
● The precise zero point correction can be calculated as follows:
Formula: Actual distance - Desired distance = Difference
Figures: 656 - 680 = -24
Calculation: Prov. ZP corr. + Difference = zero point correction
10 + (-24) = -14

● Enter the new zero point correction in the machine data. To do this, select the "Change axis data" menu,
followed by "Positions" and then "Zero point correction".
● Carry out a reference point run with the z axis.
PLEASE NOTE
The zero point correction must not exceed ± 50 digits, otherwise the axis will not find the zero pulse or will
move down too far during the reference run.
● Switch off the z axis and turn the cam disc until it reaches the end stop. If the cam disc is adjusted correctly
and if the zero point correction has been determined correctly, the following value will be obtained:
maximum travel distance: 680 digits ± 1 digit.
● Switch the z axis on again.
● Save the machine data.
● Check: the z axis must not drop after the machine is switched off.
● If necessary, carry out the zero point correction for the other two z axes.
10.3.3.2 Zero point correction for the X2/Y2 axis
● Load the SIKLEBER test program. Please read the warnings at the start of this chapter.
● Switch the machine control.

● To do this, select the "Axes" menu followed by "Z axis ..." and then "Run axis reference".
● Select the "Gantry positions" menu.
● Select the "Calibrate" menu and then "Calibrate CP". The zero point correction and the maximum and min-
imum positions for the X2 and Y2 axes will then be calculated automatically.
● Check the maximum position of the X2 and Y2 axes. The maximum position must always be larger than
2856 digits (= travel distance 50 mm). To do this, select the "Axes" menu, followed by "X2/Y2 axis", then
"Change axis data" and "Positions".
● Save the machine data.
10.3.3.3 Calibrating the PCB camera
