• Swing radius: The swing radius depends on the length of the
robotic arm and together with the axial distance it is the most
important parameter for moving accurately to a rack position. The
required values can be found in the leaflet for the robotic arm.
• Rotation offset: The rotation offset is the offset from the center of
the tower to the center of the robotic arm. Normally it does not have
to be changed. In case a Swing Head is mounted to the tower with
a lateral displacement this value can be determined with a rack
adjustment carried out by a service technician.
• Swing direction: The swing direction of the robotic arm depends
on the type of robotic arm. With a two tower model the robotic arm
at tower 1 has to be mounted right-swinging i.e. "-" and left-swinging
"+" at tower 2.
Adjustment data
With [Adjustment data] you can access an overview of the EEPROM
data of the Swing Head.
Rack tables
With [Rack tables] in the main dialog of the USB Sample Processor
you get to the list of all the racks available. The rack currently in position
is shown in green. In this dialog window new racks can be loaded or
entered and existing ones edited or deleted.
