5.1.3 General Comments
The SIPLACE 80S-20 placement machine is equipped with a pair of x-gantry and y-gantry axes which are
mechanically independent of each other. The SIPLACE 80F

gantries are of identical design. For this reason all of the servicing work
which is described in the following section will be presented on the basis of just one gantry.
The x and y axes are powered by direct current servo motors.
The position measurement system uses linear scales. For the x and y directions these are fixed directly to the
gantry axes. A read head scans the linear scales and in this way determines the position of the axis. This pro-
cedure is referred to as direct position measurement.
Power is transmitted from the direct current motors to the gantries via toothed belts and deflection.

5.1.4 Preparatory Work
We recommend that you always remove the components table before working on the gantry (see Section
12.1). This will make your servicing work much easier to perform.
5.1.4.1 Removing and Installing the Changeover Table
● Disconnect the changeover table’s electrical and pneumatic connections.
● Open the locking lever.
● With a lift truck lift the components table over the taper pins and move the changeover table out of the
machine.
● To re-install the changeover table proceed in the reverse sequence of operations.
