Single-Channel Piezo Controller, 75 V to 150 V
The ‘Output’ control is used to adjust and set the voltage or position output as
displayed in the main digital display. If the channel is in closed loop mode (set using
the 'closed loop' button on the panel) then this control can be used to adjust position
output. If open loop mode is selected (using the 'open loop' button) then the control is
used to adjust the voltage output.
1) Click the ‘Closed Loop’ button.
2) Click the ‘Position’ button.
3) Rotate the ‘Output‘ control clockwise. Notice how the position display increments
to show the increasing piezo position.
4) Rotate the ‘Output’ control anticlockwise. Notice how the position display
decrements to show the decreasing piezo position.
5) Click the ‘Voltage’ button. Notice how the display changes to show the voltage
associated with the current piezo position.
4.4.3 Jogging the Piezos
When the jog buttons are pressed, the piezo moves by the step size specified in the
Jog Step Size parameter.
1) Click the ‘Settings’ button to display the Settings panel.

2) Select the General tab as shown in above.
3) In the ‘Jog Step Size’ field, enter 0.1
4) Click ‘OK’ to save the settings and close the window.
Note
The read out in the main digital display is independent of the operating mode (open
or closed loop) selected for the particular channel. If the 'Volts' button is selected,
then the read out is in volts, even if the channel is in closed loop mode and the
Output control is being used to adjust position. Similarly, if the 'position' button is
selected, the read out is in microns, derived from the strain gauge feedback signal,
even if the channel is operating in open loop.
