Stage and Axis Type - For K10CR1 stages, the stage type is annotated automatically
when the stage is connected.
Min Pos - the stage/actuator minimum position (typically zero).
Max Pos - the stage/actuator maximum position.
Pitch - the pitch of the motor lead screw (i.e. the distance (in degrees) travelled per
revolution of the leadscrew).
Units - the ‘real world’ positioning units (degrees).
Note
This tab contains a number of parameters which are related to the
physical characteristics of the particular stage associated with the GUI
panel. They need to be set accordingly such that the stage is driven
properly by the system.
For K10CR1 stages, the APT server will automatically apply suitable
defaults for the parameters on this tab during boot up of the software.
These parameters should not be altered subsequently, as this may
adversely affect the performance of the stage.
For background information, the individual parameters are described in
the following paragraphs.
Caution
Extreme care must be taken when modifying the stage related settings that
follow. Some settings are self consistent with respect to each other, and
illegal combinations of settings can result in incorrect operation of the stage.
Note
The position display on the GUI panel will show the position up to a
maximum of 15,480° or 43 full revolutions. Beyond this, the platform will
continue to rotate but the position display is no longer accurate. To
restore the positional accuracy of the display the stage should be homed
- see Section 5.12. for more details.
