13.3.1 Removing the servo amplifier AMP-19540 from the SWS frame

Removal of the AMP-19520 servo amplifier from the wafer lift base is not described separately. The

procedure is the same.

The description shows removal of the AMP-19540 for AXIS1-4. This card is the most difficult to

access.

► Dismantle and remove the SWS from the machine (see 4.1 "Removing the SWS" [}59]).

► Fold the wafer lift out to one side (see 4.3 "Swinging up the magazine lift" [}65]).

Fig.496:

► Remove the two Allen screws on the base plate (where the BoxPC is fitted).

Fig.497:

► Remove the right side panel.

Fig.498:

► Access to the GALIL cards AMP-19540 AXIS1-4 (1) and AMP-19540 AXIS5-8 is obstructed

and therefore difficult to achieve.

TIP: to make removal of the AMP-19540 AXIS1-4 GALIL card easier (1), you can also remove the

vacuum pump and protective bracket(3).

The removal without dismantling the vacuum pump is described below.

Fig.499:

► Pull the base plate towards the front (1).

Make sure that it does not tilt too much and that the back cable of the unit is not tensioned ex-

cessively.

► Remove all cables from the AMP-19540 AXIS1-4 GALIL card (2).

NOTICE

In the diagram you can see the AMP-19520 GALIL card for the wafer lift and wafer changer

axes in the tower (3).
