Open Loop Operation - THORLABS K-Cube Piezo Controller User Manual

5.4 Open Loop Operation

The following procedures explain how the piezo actuator is driven. In open loop mode,
the piezo can be positioned in three ways: by entering a voltage, by using the 'Output'
potentiometer or by clicking the 'Jog' buttons.
5.4.1 Entering the piezo voltage
1) Click the Set Arrow
2) Enter a voltage into the pop up window. This can be entered directly into the field,
or by clicking on the up/down arrows.
3) When finished, click the Set Target Output arrow to the right of the window. The
main GUI display counts up to the value entered.
5.4.2 Jogging the Piezos
When the jog buttons are pressed, the piezo moves by the voltage step specified in
the Jog Step Size parameter.
1) Click the Step Button
2) In the 'Step Size' field, enter a step size in the range 0.1 V to 10 V. This can be
entered directly into the field, or by clicking on the up/down arrows.
3) Click 'Apply' to save the settings and close the window. To cancel the change click
Reset.
4) Click the upper Jog arrow on the GUI panel to jog the piezo. Notice that the
voltage display increments by the value entered every time the button is clicked.
5) Click the lower Jog arrow on the GUI panel. Notice that the voltage display
decrements by the value entered every time the button is clicked.
