5.2.4. Sample Positioning Stages
The stage is driven by Z812B brushed motors, which are controlled by two KDC101
devices. For optical trapping, low driving speeds are necessary. To adjust the velocity of
the servo motors you can either use the display of the KDC101 or the configuration
software. You can find the software via the Thorlabs product page
14
of either the KDC101
or the EDU-OT2(/M).
Method 1: Configuration directly via KDC101 display and wheel: Power up the
controller and open the menu on the KDC101 controller via the menu button, select “set
velocity” with the wheel and confirm with the menu button. You can now set the velocity to
the recommended 0.005 to 0.03 mm/s. Furthermore select “Joystick Mode” in the menu
and chose “Velocity Control”. This corresponds to a continuous motion of the stage when
the wheel is actuated. Confirm with the menu button.
Method 2: Configuration via Software:
The controllers can also be configured via the
Kinesis software as shown for the laser diode controller. If not installed yet, download
Kinesis and follow the installation instructions. Connect the controllers via USB when
asked or after the complete installation.
Start the Kinesis software. The controllers are shown automatically. Check the device
serial numbers in the software and on the K-cubes.
The two windows, shown in Figure 39, correspond to the two servo motors. To establish
which window controls which controller cube, press the “
Ident
” or “
Identify
” button in the
software, which will flash the display a few times on the corresponding controller.
