10.2.4.1 Removal
● To replace the z axis motor, remove the glue application head as described in Section 10.2.3.
● Loosen the clamping screw for the hub of the cam disc (M3 hexagon socket-head screw). DO NOT loosen
the screw for setting the initial tension of the cam disc bearing.
● Dismantle the motor flange from the motor support by loosening the three fixing screws
(M3 hexagon socket-head screws). These screws are accessible from the motor side.
● Pull the motor and the motor flange out from the back of the glue application head. At the same time, care-
fully remove the cam disc from the motor shaft. It is not necessary to change the initial tension of the cam
disc bearing to do this.
● Loosen the four fixing screws to dismantle the motor flange from the motor.
10.2.4.2 Installation
PLEASE NOTE:
Before assembling the motor flange, turn the motor so that the incremental encoder points downwards (plug
connection pointing to "6 o‘clock"). If the incremental encoder is pointing in another direction, there is a risk of
collision.
● Fit the motor flange to the motor by tightening the four fixing screws (M3 hexagon socket-head screws).
Please note that the incremental encoder must point downwards when the motor is installed.
● Insert the motor from the back into the motor support. At the same time, push the cam disc onto the motor
shaft. The recess in the cam disc should point to "11 o’clock" (see Fig. 10.2.3).

PLEASE NOTE:
During assembly, push the sides of the motor flange into the round countersunk hole in the motor support.
● Screw the motor flange to the motor support by tightening the three fixing screws. Please note the instruc-
tions above.
● Push the cam disc to the middle of the two cam disc bearings. The recess in the cam disc must be to the
left of the cam disc bearings, at the "11o‘clock" position (see Fig. 10.2.3). Lightly clamp the cam disc.
● Check that the cam disc lies against both cam disc bearings over the entire travel distance and that the
mechanism is running smoothly (you must always be able to turn the cam disc bearings). If this is not the
case, correct the installation position of the motor flange in the motor support.
● Leave the cam disc clamped lightly. Do not tighten it until you have set the zero point correction for the z
axis.
● Reconnect the three plugs (power supply, incremental encoder and inductive switch) to the gluing head
board. Fix the cable around the motor with a cable tie.
● Carry out a zero point correction for the z axis (see Section 10.3).
WARNING
The machine must not be started normally until the zero point correction has been carried out. You may only
load the SIKLEBER test program in order to determine the zero point correction for the z axis.
● Check the dynamic behavior settings for the z axis. If necessary, adjust the dynamic behavior as described
in Section 10.3.
● Calibrate the machine as described for situations 1 - 3 in Section 10.2.3.

● Place the new direct-drive motor in the mini-gantry, making sure that the toothed belt runs around the
toothed belt wheel. The incremental encoder on the direct-drive motor must be aligned at the back (away
from the glue application head).
● Screw in the three fixing screws of the direct-drive motor and secure with Loctite adhesive.
● Only for the Y2 axis direct-drive motor: Refit the elastomeric spring once you have tightened all three fixing
screws. Insert the elastomeric spring in the mini-gantry. Hold a hammer at the top of the mini-gantry and
then tap the clamping collar in from below.
● Connect the two plugs for the direct-drive motor to the small axis conversion board at the top of the gantry.
Fix the cable to the small axis conversion board once more using cable ties.
● Check the tension of the toothed belt and tighten, if necessary. A description of the tensioning process is
given in Section 10.3.
● Run the "Calibrate mini-gantry" function in order to determine the zero point correction and the minimum
and maximum travel distances.
● Check the dynamic behavior of the X2/Y2 axis. If necessary, set the dynamic behavior as described in
Section 10.3.
● Determine the offset between heads 1 and 2 and head 3 (see Section 10.3).
● Map the X2 and Y2 axis (see Section 10.3.3.6, page 10 - 30 -”Mapping the X2/Y2 axes (mini-gantry map-
ping)”).
