6.3 The Z-Drive and the Pipette Module
6.3.1 General Design of the Drive Mechanisms
The Z/Pipette module consists of the Z-Drive, the Pipette and the “Load and Eject”
mechanism. The roles of these three components are as follows:
The Z component is responsible for moving the module up and down its arm as
required.
The Pipette component is responsible for detecting fluid, dispensing it and aspirating
it.
The Eject component is responsible for holding a plate carrier and for ejecting a tip.
The Z/Pipette module controls the movement of the Z motor, the Pipette motor and the Eject
motor, either individually or together.
The electronics of the Z/Pipette module is presented in Figure 6-7 and Figure 6-8.
