5.3.1 Replacing the Y motor with coupling
To replace the Y motor, the die ejector must be in the bottom secure position and the SWS must be
switched off.
► Disconnect the SWS from the power supply!
► Manually move the whole wafer table until you have access to the Y motor on the base unit
and the wafer table is in the next position to the wafer lift (Y axis wafer lift stop)!
This ensures that the spindle and the bearing are as freely accessible as possible towards the Y
motor. This enables you to later lift the motor-coupling unit for removal purposes.
5.3.1.1 Removing the Y motor with coupling
Fig.51:
► Remove the front plate and disconnect the internal CAT5 cable.
Fig.52:
► Remove the cover plate on the "AD-MOT Rev.0 Sub-D board = angled", next to the Y motor.

Fig.53:
► Disconnect all connection cables (9-pin sub-D) and individual wires.
► Make a note of the connections, mark the two orange single wires SHL (see left diagram) and
HB , to avoid confusion! (The diagram on the right marks the orange SHL wire with adhesive
tape.)
► Remove the two screws fastening the coupling plate from above.
If there is a nozzle changer fitted, there are two options:
– Remove the nozzle changer, to gain access for further removal work.
– Use suitable, short hexagonal screwdrivers.
Fig.54:
► Remove the two screws fastening the coupling plate from below.
You can reach the screws via the opening for the front plate which you already removed!
DANGER
