value for the max. swing range, see the Instructions for Use for
the 786 Swing Head. This value can also be reduced if neces-
sary.
Default values:
Max. swing angle 84.00° (for titration robotic arm)
Max. swing angle 117.00° (for transfer robotic arm)
Swing radius
The swing radius depends on the length of the robotic arm
and, together with the axial distance (see above), is the most
important parameter for accurately moving to a rack position.
The distance from the robotic arm axis to the middle of the
processing head at the front of the robotic arm is decisive. The
various robotic arm models have different swing radii, see the
Instructions for Use for the 786 Swing Head.
Default values:
swing radius 110 mm (for titration robotic arm)
swing radius 112 mm (for transfer robotic arm)
Rotation offset
The rotation offset does not normally need to be altered. It is
only used if a Swing Head is to be mounted on the tower with
a lateral displacement.
Default value:
rot. offset 0.00 mm (do not alter)
Swing direction
In principle the swing direction of the robotic arm can be se-
lected as required. If two Swing Heads are mounted on a 2-
tower model then you must take care that the two robotic arms
do not come into conflict. For this reason the robotic arm at
Tower 1 should always be mounted so that it swings to the
right and that at Tower 2 to the left.
Right-swinging mounting means: swing direction –
Left-swinging mounting means: swing direction +
Default values:
Swing direction: – (at Tower 1, swing to the right)
Swing direction: + (at Tower 2, swing to the left)
