Note: The controller will prevent the inputting of parameters that are outside the
permitted range of the device in question. If required, these parameters can be viewed
via the PC GUI described in Chapter 5.
4.5 Moving the Stage
Manually moving motorized stages using the BBD30x is simple, and can be done via
two methods:
1) By using pre-selected positions (up to 3) found under the "Teach" tab. In this mode,
the stage travels directly to the requested position at the speed/acceleration
currently loaded into the firmware. Simply press the button corresponding to
Position 1/2/3 to send the stage to that point. See Section 4.6. on how to change
these set-points.
2) By using the control knob on the front panel to increment/decrement the stage
position. There are two options for how this is done:
Jog Mode, whereby turning the control knob allows motion in either direction, one
step at a time: keep turning the knob for further steps. Allow the knob to return to
its zero potion, and twist again for more steps.
Continuous Mode, whereby the stage will continuously move whilst the control
knob is rotated in the "+" or "-" direction. The further the knob is rotated, the faster
it moves - up to the maximum velocity that has been set for the motor.
See Section 4.7. for how the control knob functionality can be changed.
4.6 The Teach Facility: Inputting Stage Set-Points
On the title page of any chosen motor channel, the Teach facility is directly available
(3rd button down - see Fig. 4.3b). Pressing this reveals a page similar to that shown in
Fig. 4.5a, where the current set-points are indicated. Pressing Pos1/Pos2/ Pos3 will
send the stage to those points.
However, if an alternative set-point position is required, use the control knob to place
the stage at the required position (the current position is indicated on the screen on
the right-hand side, even when moving), then hold down the button corresponding to
the position that needs to be set. Wait for the white progress bar in the bottom right-
hand corner to complete (see Fig. 4.5b), and the button can now be released. The new
set-point should then appear on the panel, and this will now have been loaded into the
firmware for future use. When finished, press 'Exit'.
Note that if precise calibration positions are required, this may be better achieved
through the APT software control option, described in Chapters 5 and 6.
