Software Support for AnalogPiezo Controllers
Optimizing System Performance Using Digital Piezo Controllers with PI Software
Analog piezo controllers with-out a digital interface are sup-ported by PI software with a set
of LabVIEW drivers in combina-
tion with a DAQ board (see
page 6). Global Technical Support,Firmware Updates, Calibration PI maintains nanometrologylabs with state-of-the art cali-
bration equipment on three
continents. Should a nanoposi-
tioning system require recali-bration or user-specified cus-tom tuning, an experienced PI
service engineer will be able to
support you. PI applications
engineers can also help you
with firmware and softwareupdates or other system adap-tations.
Convenient operation and optimization of piezosystems Operation of Digital & Analog Piezocontrollers NanoCapture™ Application Software Offers Simple Interface Enables Optimization of All Servo Parameters Displays Response Behavior & Resonant Frequency, Creates Bode Plots Comprehensive System Optimization NanoCapture™ provides basicand highly advanced functions
for operating digital piezo
servo controllers. With its
graphical interface, Nano-Capture™ enables convenientsystem optimization and can
display settling behavior, reso-
nant frequency, Bode plots, etc.
If the nanopositioning system
is equipped with directly meas-uring
position sensors, thesefeatures are available with no
additional instrumentation. In addition, NanoCapture™supports numerous controller-
specific properties.Wave Generator: synchronizedoperation of multiple axes withmathematically defined curves,or with arbitrarily costomized
functions (see page 7). The functions described aboveare especially useful when the
mechanical properties of the
system calibrated at the factoryare changed, e.g. by applying ahigher load.In such a case, the adjustmentof parameters like control-loop
amplification (P-I parameters),notch filter frequency or thezero-point of the integrated
sensors, can optimize response
behavior and system stability.
