About fine-tuning robot teachpoints
Where teachpoints
are used
Teachpoints are axis position coordinates needed by:
❑
The robot, to be able to accurately pick up and move plates to and
from devices
❑
VPrep heads, to be able to accurately position pipette tips into plate
wells
❑
VSpin centrifuges, to be able to accurately position the buckets in
relation to the door
❑
VStack stackers, to be able to accurately position the plate stage
during operation
Teachpoint coordinates are relative to the robot’s or device’s home
position and are set up by Velocity11 before shipping and verified at
your site on installation. However, you might occasionally need to fine-
tune teachpoints.
For information about device teachpoints, see the relevant user manual.
This topic covers only robot teachpoints.
Robot teachpoints
defined When teachpoints are initially set at the factory, they are defined as
described in the following table.
Retry pushdown Pushdown is a robot action used
with filtration stations, vacuum
platepads and vacuum shelves on
VPrep pipettors.
The purpose of the action is to
flatten a plate on the stage. If,
during operation, the vacuum seal
indicator indicates the absence of
a seal, the robot will push down on
the plate in an attempt to create a
seal.
The value for this parameter is the
distance pushed down in
millimeters.
