If a Swing Head drive is mounted with a 6.2058.020 adapter in order to
use racks smaller than intended, then the axial distance must be modi-
fied in the configuration of the control software. The corresponding data
can be found on the accompanying sheet of the 6.2058.020. The axial
distance refers to the distance of the swing axis (see figure) and of the axis
of rotation (middle point) of the sample rack.
