In the figure below, the
Device Parameter Configuration
window shows the
Sensor

parameter group.
2.
Save the parameter values from the
Edit Mask
column of the
Device Parameter Configuration
window in a parameter file (file extension .pam) on your PC. Use one of the following options:
−
File > Save Edit Values
or
File > Save Edit Values As
menu item
−
(Save) or (Save As) button in the icon bar
Executing Test Motions in Open-Loop Operation
The first moves should be made in open-loop operation. With the factory default settings of the E-
727, open-loop commanding means to give open-loop values which correspond approximately to
axis positions.
1.
In the main window of PIMikroMove, make some test moves with the individual axes using the
controls on the
Axes
tab card. During the test moves, observe the position display for the axes
(in the
Current Value / Position
fields) and the current output voltage(s) for the piezo
actuator(s) in the stage(s) (in the
Output Value
fields of the
Output Channels
tab card).
Proceed as follows for each linear axis (for rotation axes, the given open-loop values
correspond approximately to positions in µrad or mrad, and the step size can be set to a
larger value, for example 100 µrad):
a)
Make sure that the
Servo
box is unchecked.
b)
Command an open-loop value of 0 (µm) by entering 0 in the
Open-Loop Target Value
field of the axis and pressing
Enter
on your keyboard.
c)
Enter the value 10 (µm) in the
Step size
field of the axis and press
Enter
.
d)
Use the
>
button next to the
Open-Loop Target Value
field to increment the
commanded value by the value given in the
Step size
field (10). Increment the open-
loop value this way step by step up to the upper travel range limit of the axis.
e)
Use the
<
button next to the
Open-Loop Target Value
field to decrement the
commanded value by the value given in the
Step size
field (10). Decrement the open-
loop value this way step by step back to zero.
