PiezoWalk® Precision Drives –
Millimeter Travel, Nanometer
Resolution, High Forces
PiezoWalk® drives break awayfrom the limitations of conven-tional Nanopositioning actua-tors. They offer a basically
unlimited travel range andstill provide the characteristicfeatures of a piezoelectricactuator: an open-loop resolu-tion down to 30 picometers anda very high stiffness for dynam-ic operation and force genera-tion. PI offers two product lines
� PiezoWalk® drives are availa-ble for non-magnetic appli-cations such as super-con-ductivity experiments. Theydo not create magneticfields nor are they influen-ced by them.
� The active parts inPiezoWalk® drives are madeof vacuum-compatible cera-mics. The drives also workin UV-light environments.
� NEXLINE® drives can surviveshock loads of several gduring transportation.
� PiezoWalk® drives are available in three levels of integration to provide flexibility for OEMs: OEMdrives, packaged actuatorsand integrated into complex positioningsystems such as multi-axistranslation stages or 6-DOFHexapods.
based on different versions of the PiezoWalk® principle: NEXLINE® and NEXACT®. Bothprovide specific advantagesdepending on the application.
PiezoWalk® piezo steppingdrives usually consist of sever-al individual piezo actuatorsand generate motion throughsuccession of coordinatedclamp / unclamp and shear-motion cycles (steps). Eachcycle provides only a fewmicrons of movement, but run-ning at hundreds of hertz, thedrive achieves continuousmotion in the mm/secondrange.
The PiezoWalk® working princi-ple provides high force capabil-ities, resolution and repeatabil-
ity. These properties are typi-cally better for piezo steppingactuators compared to inertiadrives or ultrasonic motors.The operation is possible intwo different modes: a high-resolution, high dynamics ana-log mode within a single step,and a step mode with virtuallyunlimited travel range.

Features and Advantages of
PiezoWalk® Drives
� Very high resolution, limitedtypically only by the sensor.In fine-adjustment, analogmode, resolution of 30 pico-meters has been demonstra-ted.
� High force generation andstiffness. NEXLINE® drivescan hold and generate for-ces to 600 N, NEXACT® to15 N.
� PiezoWalk® drives hold astable position to nanome-ter level in power-off mode.Due to the actuator design,the maximum clampingforce is applied at rest.
� Because a position can beheld with zero operating vol-tage, leakage currents can-not affect the integrity of thepiezo drive.

NEXLINE® High-Force Drives
for Nanopositioning
NEXLINE® systems are basedon very rugged, high-efficiencyshear and clamping actuatorsand incorporate a preloadingmechanism to provide pushingand holding forces up to 600 Nwith high lifetime. The rigiddesign with resonant frequen-cies of hundreds of hertz allowsthe construction of very stiffstructures and helps to sup-press vibration. The analogoperating mode can be usedfor dithering and active vibra-tion cancellation.
Compact NEXACT® Drives for
Moderate Forces
NEXACT® drives use bendingactuators which combine thefeed forward and the clampingcycles. They provide push/pullforces to 15 N with maximumvelocities of more than 10 mm/s at low operating volt-ages of 40 V. The compact andcost-effective NEXACT® drivesare available with various driveelectronics, ranging from cost-effective OEM drives for open-loop operation in steppingmode to the sophisticated E-861 servo-controller for high-resolution, closed-loop lineartranslation stages.

Advantages of PiezoWalk®
piezo stepping drives
NEXLINE® and NEXACT® drivesoffer several advantages overtraditional drive technologies:� Resolution in the picometer
range� Compact dimensions� High drive forces from ten
newtons (NEXACT®) up toseveral hundred newtons(NEXLINE®)
� High dynamic performancewith sub-microsecond res-ponse
� Self-locking when powereddown; no holding current
� Zero backlash, no wear ormaintenance, no mechani-cal components like gearsor leadscrews.
� Non-Magnetic and VacuumCompatible Operating Prin-ciple
Working Principle for
Application Flexibility
NEXACT® PiezoWalk® technolo-gy overcomes the limitationsof conventional nanoposition-ing drives and combines virtu-ally unlimited travel rangeswith high stiffness in a verysmall package. Furthermore,NEXACT® actuators providepiezo-class resolution (farbelow one nanometer) andmillisecond responsiveness.The special drive designreduces the operating voltageto 40 V and below.
In operation, piezoceramicbending elements act on therunner, which is connected tothe moving part of the applica-tion. The length of the runnerdetermines the travel range.Force capacity, resolution andvelocity are determined bythe piezo geometry anddrive electronics and arescalable. To move the runnerover longer distances thesteping mode is used, whereasfor distances smaller than onestep, the linear (analog) modeenables high-dynamics posi-tioning with resolutions farbelow one nanometer.
Wear and Maintenance-Free
In contrast to ordinary DC orstepper motor drives, thePiezoWalk® drives effect linearmotion directly, without theneed to transform rotation withmechanical elements such as gears, leadscrews and nuts. Therefore, mechanical
limitations such as backlashand wear are eliminated andthe drive is maintenance-free.
Self-Locking PiezoWalk® Piezo
Stepping Drive
NEXLINE® and NEXACT® exhib-it high stiffness and are self-locking even when powereddown due to the clampingaction of the piezo actuators inthe mechanics. This entailsnanometer position stability atrest, with no heat dissipationor servo-dither.
Controller and Drive
Electronics appropriated for
the Application
NEXACT® actuators requirespecial drive electronics tocontrol the complex steppingsequences. The E-860 seriesNEXACT® controllers are avail-able in different open-andclosed-loop versions. Forexample, the E-861 includes acomplete NEXACT® servo-con-troller with low-noise, 24-bitdrivers and a powerful DSP. Italso comes with ample soft-ware for easy integration andhighly effective computer con-trol. For applications which donot require the highest resolu-tion lower-priced drive elec-tronics, ranging all the way toOEM boards, can be ordered.

NEXLINE® Working Principle
for Application Flexibility
NEXLINE® PiezoWalk® drivescan be used wherever highloads must be positioned veryprecisely over long distancesand then perhaps subjected tosmall-amplitude dynamic ad-justment, as for active vibra-tion control. By varying thecombination of longitudinaland shear piezo elements, thestep size, dynamic operatingrange (analog travel), clampingforce, speed and stiffness can
all be optimized for a particularapplication.
NEXLINE® PiezoWalk® Piezo-ceramic clamping and shearelements act directly on a mov-ing runner that is coupled tothe moved object. While therunner can be moved largerdistances in step mode, analogoperation over a distance ofless than one step enableshigh-dynamics positioningwith resolutions far below onenanometer. The patentedPiezoWalk® overcomes thelimitations of conventionalnanopositioning actuators andcombines long travel rangeswith high resolution and stiff-ness.

N-214 · N-215NEXLINE® High-Load Piezo Nanopositioning Stepping Drive
The innovative N-214 / N-215NEXLINE® OEM linear drivesare ultra-precision nanoposi-tioning actuators with travelranges to 20 mm and push /pull forces to 400 N. The novel,patented NEXLINE® PiezoWalk®
drive design combines longtravel ranges with highmechanical stiffness and piezo-class resolution of better than0.1 nm.
PiezoWalk® supports two differ-ent motion modes: a high-reso-lution, high-dynamics shortrange (analog) mode and astepping mode with virtuallyunlimited travel range.
Two versions are available, theN-214 closed-loop model andN-215 open-loop model. Bothcan be operated with thesophisticated E-755 NEXLINE®
motion controller. The N-214 isequipped with a 5 nm resolu-tion linear encoder for long-range position control. Due toits low-noise, 24 bit D/A conver-ters, the E-755 controller canprovide picometer level resolu-tion in the highly-dynamicshort-range / dithering mode.
NEXLINE® Working Principle
for Application Flexibility
NEXLINE® PiezoWalk® drivescan be used wherever highloads must be positioned veryprecisely over long distancesand then perhaps subjected tosmall-amplitude dynamic ad-
justment, as for active vibra-tion control. By varying thecombination of longitudinaland shear piezo elements, thestep size, dynamic operatingrange (analog travel), clampingforce, speed and stiffness canall be optimized for a particularapplication.
NEXLINE® PiezoWalk® Piezo-ceramic clamping and shearelements act directly on a mov-ing runner that is coupled tothe moved object. While therunner can be moved largerdistances in step mode, analogoperation over a distance ofless than one step enableshigh-dynamics positioningwith resolutions far below one nanometer. The patentedPiezoWalk® overcomes the limi-tations of conventional nanopo-sitioning actuators and com-bines long travel ranges withhigh resolution and stiffness.
High-Resolution Dynamic
Operation
In analog mode the motion iseffectuated exclusively by thevery stiff shear elements, pro-viding a resonant frequency inthe direction of motion of sev-eral kilohertz. The motion reso-lution here is limited only bythe stability of the drive elec-tronics, or, in closed-loop oper-ation, by the sensor.
Basically Unlimited Travel
Range
Step mode involves a sequenceof coordinated shear and
clamping moves. That is whypiezo stepping drives have nointrinsic travel limitation andcan be used flexibly. The max.step frequency of 100 Hz and isdetermined by the controller.It allows velocities up to1 mm/s, depending on the stepsize and / or analog range.
Unlimited Lifetime
The application area of NEX-LINE® drives often lies in thedifficult-to-access internals ofmachines, where nanometer-realm adjustment and vibrationcancellation are required.
Long lifetime is therefore abasic requirement for NEX-LINE® actuators. To promotelong lifetime, the controller canreduce the operating voltageon all the piezo elements tozero at any position and stillmaintain the full holding force.

NEXLINE® linear actuator principle
12
E-755 digital nanopositioningcontrollers are designed todrive the novel, patented,NEXLINE® nanopositioning lin-ear drives. Combining ad-vanced control technologyand sensor signal processingwith special drive algorithms,the E-755 can provide preci-sion motion control over hun-dreds of millimeters with pico-meter-range resolution.
Coordinated action of shear-ing and clamping piezo ele-ments is what allows NEX-LINE® to break through thebarriers of conventional nano-positioning actuators.
The E-755 offers two differentcontrol modes: a high-resolu-tion, high dynamics directpiezo mode, with basically un-limited resolution, and a long-range mode with virtuallyunlimited travel range.
High-Resolution Closed-Loop
Control
E-755 controllers are based onpowerful 32-bit DSPs andcome in open- and closed-loop versions. Both versionsfeature four high-resolution(24-bit) linear amplifiers withan output range of ±250 Vrequired to control a single-axis NEXLINE® drive. For theclosed-loop models, high-res-olution incremental positionsensors to sub-nanometer res-olution are supported by spe-
cial excitation and read-outelectronics. A power-downroutine in the E-755 firmwaresaves the current position,allowing a closed-loop systemto be ready for use withoutreferencing next time it ispowered up.
Zero-Voltage Control Mode
Promotes Extreme Actuator
Lifetime
NEXLINE® nanopositioning ac-tuators can often be found ininaccessible locations deepinside complex equipment,where nanometer-precise alignment and vibration can-cellation are required. Thismakes the long lifetime ofNEXLINE® drives especiallyadvantageous. The E-755 firm-ware incorporates a specialprocedure to bring the NEX-LINE® actuator to a full-hold-ing-force zero-drive-voltagecondition, no matter where itis along its travel range. Thiseliminates long-term offsetvoltages, which can limit thelifetime of conventional piezodrives.
Linearization
E-755-controlled nanoposi-tioning systems provide out-standing linearity, achieved bydigital polynomial lineariza-tion. The linearization canimprove linearity to 0.001 %over the full travel range.
