Chapter 4 Operation
4.1 General
The filter wheels are connected to the controller via a flying lead terminated in a D-
type connector.
For a complete tutorial on using the stage with a motor controller, see the relevant
controller manual. Basic steps in controlling the stage are as follows:
1) Connect the stage to the DC motor driver - see Section 3.3.
2) Run the software and associate the controller serial number, stage type and
channel number – see Section 4.2.
3) Move the stage to its home position, to establish a zero datum - see the handbook
supplied with the controller unit.
Caution
It is recommended that the FW103 filter wheel is driven by either the Thorlabs
KST101 K-Cube stepper motor driver or the BSC201 benchtop stepper motor
controller. If the wheel is being driven by any other driver or controller, consult
Section B.1. for motor pin out details and Appendix B for details of the motor
specification.
Warning
The controller must be switched OFF before the stages are plugged in or
unplugged. Failure to switch the controller off may result in damage to either the
controller, the stage, or both.
Note
For large moves (i.e. greater than 60°) the velocity may need to be reduced in order
to avoid stalling the motor.
Errors can accumulate if the wheel is jogged repeatedly. To avoid such errors when
large moves are required, click on the position display in the GUI panel and enter in
the pop up window the number of degrees to move.
