The axis must now be referenced by clicking on « Home » button:
The axis is now ready to be used.
Note
:
A preset value can be set to the current position. See chapter:

Axial Load verification
For stages equipped with a position sensor, the following tests can be performed to
verify axis behavior based on an axial load.
5.3.3.1
No axial Load
All Newport piezoelectric stages are tested and calibrated in the factory. Calibration
parameters (saved in the stage’s EEPROM) allow the driver board to set the XPS
controller scale Zero position at the stage origin.
With no applied power, any Newport piezoelectric stage rests in an equilibrium or rest
position based on actuator’s hysteresis. Although very close, this position is always
slightly different from the stage origin (within 5% of the total travel range).
The value at this rest position can be obtained using XPS Website « terminal » page.
Note:
Axis must be disabled prior to using this command
In the list, select the command: « PositionerDriverPositionOffsetsGet » then click on
« OK » and finally « Execute »
The command returns 3 numbers separated by comas:
-
The first “0” indicates the correct execution of the command.
-
The second number indicates the current value (in microns) of the
« DriverStagePositionOffset » parameter of the « stages.ini » file. See chapter:
Offset

. (Default value: “0”)
