Extensive Software Support The controller comes with alarge variety of software tools,
such as the NanoCapture™
system analysis program,
LabView™ drivers and Win-dows Highest Linearity High-Bandwidth AnalogInterface In order to achieve the highestdegree of linearity over the
entire travel range, the E-761
uses a number of innovative
techniques: A hardware-basedsystem in the sensor-proces-sing electronics known as ILS
(Integrated Linearization Sys-
tem). In addition, a firmware-
based system uses polynomi-
al linearization for the entireelectronics and mechanicssections. By this combination
the highest possible positio-
ning accuracy is ensured.The Wave Generator in the E-761 controller makes possi-ble synchronous motion ofdifferent axes according to
user-specified patterns (prede-
fined either with mathematical
functions, or arbitrarily, stored
in internal tables). Flexible Configuration The analog input can be usedas a direct control input. Theapplied voltage is then inter-
preted e.g. as target value and
can be used to drive one or
more axis. It is also possible to
use the analog input for trig-
gering tasks. E-761 digital piezo controllersand PI nanopositioning stageswith ID-Chip can be operated
in any combination, support-
ed by the controllers’ Auto-
Calibration Function. Indivi-
dual stage data and optimizedservo-control parameter arestored in the ID-Chip and are
read out automatically by thedigital controllers. >

PCI Board Digital controllers have anumber of advantages over
conventional piezo control-
lers: Sensor and actuator axesneed not be parallel to eachother, or to the orthogonal
logical axes used to command
the system. For instance, rota-
tion can be added to XY-
motion (see the P-527.RCDnanopositioning stage), or tilterrors can be reduced. The fle-
xible coordinate transforma-
tion algorithm permits opera-
tion of complex, multi-axis,
parallel
metrology stages.With parallel motion metrolo-gy, the controller monitors all
controlled degrees of freedom
relative to “ground” (the fixed
frame) and uses each actuator
to compensate the undesiredoff-axis motion of the others
automatically (active trajecto-ry control). High-end nanopo-sitioning systems with active
trajectory control can attain
motion accuracies in the sub-
nanometer range. >

(GCS) General Command Set
(GCS) is PI’s universal com-
mand set for uniform controlof nano- and microposition-ing systems. Most PI nano High-Speed PCI Interface Additional High-Bandwidth Analog Interface 32-Bit Digital
Industrial filters 24-Bit
DAC Resolution 2 Linearization Systems Coordinate Transformation for Parallel Kinematics / Parallel Metrology Systems po-sitioning and micropositioning ID-Chip Support for Automatic Calibration controllers including hexapod
systems support this com-mand set. By GCS the control
is independent of the used
hardware, so that different
devices can be controlled
together or new devices can
be used with minimum pro-gramming expenditure. Theproduction of own application
programs becomes clearly
simpler owing to GCS, since
the commands for all support-
ed devices are identical in syn-tax and function. Otherwisenecessary training can be
omitted completely. Appli-
cation development is acceler-
ated by the use of the GCS
command set observably,
since comfortable high-levelfunctions are used. This de-creases at the same time the
error probability. The simple
use of the GCS takes place in
form of a universal PI-
LabView™ driver set (VIs), aWindows Extensive Software Package E-761 digital piezo controllersoffer advanced control tech-nology in a cost-efficient PCI-board format. These control-
lers can control piezo-driven
nanopositioning systems with
up to three logical axis (four
integrated piezo amplifiers!).
E-761 are based on extremelylow-noise
industrial power amplifiers,highly advanced 24-bit digital
analog converters (DAC) and
powerful 32-bit digital signal
processors (
INDUSTRIAL DSP).Having PCI-board format theE-761 digital controller can be
easily implemented in all cur-
rent PCs and industry-PCs,
allowing for easy integration
with other devices such as
frame grabbers. The PCI inter-face with its high bandwidthallows for a very fast commu-
nication between software
and controller. This is a defini-
te plus in time-critical applica-
tions or when controllingseveral axis. >
