ABOUT PIEZOMOTOR AB PiezoMotor is one of the world-leading developers and manufacturers of direct drive, micro motors based on piezoelectric materials. Simple, precise and very small, piezoelectric motors are replacing traditional electromagnetic motors when these no longer meet the demands. Piezo LEGS速 motors minimize total product size and deliver much greater precision. At the company head office in Uppsala Sweden we make sure to have full control from piezo powder to delivering the final motor. This means that within our facilities we have a team of developers designing our motors, a production team to manufacture the piezoceramic material and assemble the motors, and the sales team to support our customers and distributors. Across the world, there is an ever increasing need for small, strong motors. Miniaturization combined with precision is driven by demand for higher accuracy in manufacturing such as precision machinery and measuring tools. In the medical sector, we see analytical instruments and manipulators becoming more and more advanced and exact. The development of nano technology is further enhancing this development. In the semiconductor industry, there are continuous efforts to develop higher precision instruments in order to scale down devices on the silicon wafer. In many of these applications, conventional electrical motors do not meet the required features. Our small, strong motors are precise down to the nanometer range. In addition, it has instant response time and does not suffer from the backlash problems which no gearbox can escape from.

Markets Piezo LEGS® motors are very flexible. They find use in a wide range of applications and markets, a number of which are outlined below. OPTICS Moving mirrors and lenses in optical applications is a traditional PiezoMotor application. The motors’ open-loop and closed-loop operation makes them particularly attractive in this market. High resolution, high stiffness and high holding force – even without power applied – are additional key success factors. Our LTC type Piezo LEGS motors have dedicated solutions for different mirror mounts. We also offer customized solutions
SEMICON Trends in the semiconductor sector indicate a shift in focus from everfiner trace width to greater emphasis on advanced packaging. Production capabilities and throughput remain very important. Piezo LEGS motors deliver high throughput, thanks to fast settling times plus high stability and resolution. PiezoMotor continuously develops new products for this market – both motors and drivers. We know this sector. Its demanding environment is part of our everyday life. Most of our solutions are customized.
SEM/TEM Requirements for higher resolution and newer, faster automated sequences continue to drive motor and driver development in the SEM/ TEM sector. The extremely high resolution of Piezo LEGS motors matches this need perfectly. Fractions of an Ångström plus high stiffness and stability are combined with low heat dissipation into systems. Our motors are fully compatible with the vacuum environment. For the most demanding applications, they can be made completely non-magnetic.
FACTORY AUTOMATION This market is still in its early stages, but a steady increase in the use of Piezo LEGS motors is already evident. Driving forces include increasing demands on high-end assembly equipment plus smaller and smaller parts. Piezo LEGS motors are suitable for slow-speed, high-precision applications. We work together with many motion control specialists, mixing different technologies with Piezo LEGS motors and thereby building optimized motion solutions. Piezo LEGS motors perform well in many applications, but if other solutions appear better, e.g. those offered by our Faulhaber Group partner, we don’t hesitate to recommend them.

MEDTECH Compact high-resolution solutions are key success factors for many medtech applications such as probing and cell manipulation. Our motors find many uses here and their very fast settling time is much appreciated by end-users. Fast settling time, in combination with high resolution and slow-speed, makes Piezo LEGS solutions very competitive.
STAGE Linear and rotary stages are common building blocks in almost all of the markets mentioned above. PiezoMotor offers a wide range of products for motorizing stages. Our motors can be fully integrated for very compact solutions or mounted externally with a minimum of components. Moreover, Piezo LEGS technology makes it possible to replace an existing DC/ Brushless/Stepper solution with a high-resolution piezo alternative. Systems also require position sensors to provide feedback for closedloop operation. We offer sensors from Renishaw and MicroE Systems, and we help find the solution that best matches your application needs.
DEFENSE Military applications often require very robust solutions and even here, friction-based Piezo LEGS motors offer a very good fit. Friction-based motors can be subjected to impact or even being manually moved without any damage to the motor; if the force applied to the motor is higher than the holding force, it will just start sliding. Automatic locking without power consumption is a unique feature that makes our motors suitable for battery-operated equipment. In airborne applications, the very high force-to-weight ratio is also an important success factor.
CUSTOMIZED PRODUCTS Over the years, we have gained much experience with custom adaptations, both with mechanics and electronics. We have the building blocks, skills and experience to make motor solutions to meet your needs. We do in-house sub-assembly of full-motion systems (i.e. motor, guiding, encoder). Contact us to discuss details with our skilled engineers.

How it works OLD PHENOMENA USED IN NEW AND EXCITING WAYS The piezoelectric effect was discovered in the 1880’s by the Curie brothers. By applying voltage to a piezo electric material, they were able to change its shape. This effect has since been used in many applications; submarine sonars, ultra-sound equipment at hospitals, as well as loudspeakers, for example. A more recent application – piezo-actuated fuel injectors – has improved the fuel economy of modern cars and trucks. This would not be possible without robust piezo electric components able to endure billions of cycles in the harsh environment of the combustion engine. Until PiezoMotor demonstrated its first commercially available piezo motor in 2002, only a handful of manufacturers existed. Since then, the acceptance of piezo technology has increased dramatically and more and more customers are today enjoying the benefits that our motors deliver.
ROCHELLE SALT
AN OUTSTANDING SUCCESS STORY The conventional electromagnetic motor is one of the most successful industrial products of all times. Since its conception some 175 years ago, it has made inroads into every aspect of our lives. Today, close to 10 billion small electric motors are produced each year. What’s more, the numbers keep growing as new applications are added to the list. In the most basic modern car, for example, we find some 30 to 40 motors handling everything from adjusting rear-view mirrors to opening windows. In a luxury car, close to one hundred motors are used.
SO WHY DO WE NEED ANOTHER TYPE OF MOTOR? The answer is that for most applications we don’t; the well-proven electromagnetic motor will work just fine. But for a growing number of applications and products, this traditional solution has reached the end of the road. A new type of motor is replacing it – a piezoelectric motor – and the demand is growing. All underlying trends support this growth; we want smaller and smaller products, more and more portable devices with more features and longer battery life, plus greater energy efficiency and higher and higher precision.

PIEZO LEGS® MOTOR ELEMENT
PIEZO LEGS® TECHNOLOGY Piezo LEGS is in essence a walking machine constructed in one solid piece. Constructed so that each leg can be elongated as well as bent sideways, it moves incrementally by synchronizing the movement of each pair of its four legs, just as an animal would. Note that Piezo LEGS operates directly – there’s no need for gears or mechanical transmission, and the material itself is virtually impossible to wear out. Even if the motor moves incrementally in the nanometer range, it can still be very quick. By taking thousands of steps per second, it can cruise along at centimeter per second speeds.
How it moves STEP-BY-STEP Orange arrows show the direction of motion of each leg tip. They move as alternate pairs. White arrow show the movement of the rod.

DIFFERENT TYPES OF PIEZO LEGS® MOTORS Piezo LEGS motors are designed for ‘move-and-hold’ applications where precision, minimal space, low energy consumption and simple mechanical design are important factors. As the motor is non-resonant, it is also very easy to scale up and down in size. Unlike resonant piezoelectric motors, which only operate at a given frequency, Piezo LEGS motors offer extraordinary speed dynamics. They can be operated at extremely low speeds (nanometers per second) up to 20 mm/second with full control in the complete dynamic range. A further unique feature is their ability to take extremely small steps (single nanometer range) in combination with long strokes. This means that one Piezo LEGS motor can often replace two motion systems – a DC-motor plus a piezo actuator, for example – without sacrificing performance. So what do you need to design and integrate a motion system based on Piezo LEGS? To start with, we offer standard Piezo LEGS motors in various sizes plus a range of drivers/controllers. We also help select suitable position sensors as well as guidance and/or design of the mechanical interface of the motor. Our experienced mechanical and electronic designers help you throughout the process.

WHY USE AN ELECTROMECHANICAL PIEZO MOTOR INSTEAD OF A TRADITIONAL ELECTROMAGNETIC The electromagnetic motor has continuously improved since Michael Faraday converted electrical energy into mechanical motion in 1821. The principle has now reached a stage of very high refinement and precision and is the most widespread industrial product in the world. Piezo LEGS rely on an electro-mechanical principle rather than an electromagnetic one. So what are the differences and what benefits do you get by switching to the new technology? To answer these questions, let’s take a look at the basics of the different principles. The electromagnetic motor works by creating force through magnetic poles that repel each other. Electrical current fed through wound coils create a magnetic field, where polarity is sequentially reversed to make the rotor spin. Piezo LEGS instead works with direct friction drive; force is created by the inherent preload of the piezoceramic actuator legs in direct friction contact with the rotor or drive shaft. When the legs start walking they are always in mechanical contact. In the following text we will explain how this is beneficial.
RESPONSE AND SETTLING TIME When using a magnetic field to accelerate the rotor of a DC motor, you will always have lag due to inertia. More so, the electrical impedance in the windings of the motor will negatively affect the response time; it simply takes time to push current into the motor to create the electromagnetic field. When settling in on a target position with a DC motor you will have an overshoot and must deal with oscillation. The time to settle and the continuous dithering may be a killer for any precise application. Piezo LEGS motors work with direct friction drive and will hold the load tightly. Response and settling time is limited by the load and friction between the piezo actuators and the component to be moved. Responsiveness of the piezo actuators is instantaneous and settling time is much faster compared to any traditional motor technology.

STIFFNESS In many high accuracy applications, motion stiffness is essential. A system designed for holding force by magnetic field is of course a bit spongy in its nature. Stiffness can be increased with different tricks, but in comparison with the Piezo LEGS the traditional motor technologies fall short. Piezo LEGS are firmly holding the rotor or the linear shaft, and consequently you will make use of the high stiffness of the ceramic material. With increasing motor size the level of stiffness will only get higher.
FORCE In relation to its size, the torque of a rotating electromagnetic motor or the force of a linear electromagnetic motor is much lower than for Piezo LEGS. This is especially significant in small diameter motors. That’s the reason why electromagnetic motors need a gearbox to create high force and torque. Piezo LEGS motors do not need gearboxes. Piezo LEGS is selflocking and will hold load even when powered off.
RESOLUTION, MINIMUM INCREMENTAL MOTION In precision positioning, the term Minimum Incremental Motion (MIM) is often used. This is the smallest practical mechanical motion on the outgoing axis. Traditionally, we always see a big difference between the MIM and the resolution, since the latter is more closely related to the smallest detectable motion. In contrast, Piezo LEGS dramatically decrease the gap between MIM and resolution, in many cases eliminating it entirely. Resolution is more dependent on the electronics and the position sensor; the limiting factor is not the motor itself. Piezo LEGS thus achieve resolution so high that traditional electromagnetic motors are not even close. You will be able to easily position on a sub-micron level, or even down to sub-nanometers. For the rotary Piezo LEGS we’re talking sub-microradians.
BACKLASH Backlash is another factor that creates a lot of problems in motion. To illustrate this, you simply have to look at an adjustable spanner in your workshop. Changing the moving direction of the adjustment screw and nothing happens at first because of the play in the mechanics. Motion is created, but only after some delay. This is also the case in all gearboxes as the force is applied on different sides of the gears. There are of course ways of minimizing the backlash in gears, but to have a completely backlash free motion you need the direct drive feature of Piezo LEGS; friction contact is always in place, and changing direction can be done without the slightest play.
LTC20 AND LTC40
ACCURACY Absolute accuracy is the maximum difference between absolute target position and actual position. As we have seen, accuracy is limited by backlash and nonlinearity of the drive mechanics, while other factors that contribute to inaccuracy include temperature drift. What is clear is that achieving the best accuracy requires direct drive and direct metrology systems. For best accuracy the only option is to have position feedback from the point of interest; you simply place the position encoder close to where you want to measure movement.
ENERGY CONSUMPTION Traditional electromagnetic motors use significant amounts of energy just to keep a motor in a fixed position. Continuous current generate heat in the windings of the DC motor, and can have very unwelcome effects, especially in high-end positioning. Switching off the current will cause the motor to loose its position. Piezo LEGS motors are by far less energy consuming. The capacitive load of the piezoceramic actuators means power is consumed only when moving. When at stand still the motor will hold position without any current draw. For point-to-point movements you will see a really efficient use of energy, and at stand still you will have no heat generation. More so, the torque/force Piezo LEGS can deliver for the amount of power consumed is remarkable.
CONCLUSION
LT40
Regardless of your application, it’s highly likely that your next development will have greater motion demands than the last. Many of the problems noted above will require a speedy solution. Switching to Piezo LEGS simply solves so many problems. In many cases, the improvement is dramatic. We see a fast-growing use of Piezo LEGS. More often than not, using one of our motors is no longer an optional alternative to the electromagnetic motor – it’s a necessity for driving product development forward.

Electronics Standard drive electronics for Piezo LEGS速 range from simple and low cost to advanced controllers for closed loop control. The motor is powered by signals below 50 V in amplitude, and custom drive circuitry can even run on battery.
Piezo LEGS motors can be used in different ways depending on the requirements of the particular application. Required resolution is always the key question. As its name implies, a Piezo LEGS motor takes steps to create motion and, just as in humans, it can walk in different ways. It can move fast or slow, take long steps, short steps or partial steps, and stop at any point. All accomplished by different movement patterns and frequencies of the legs. If we study one of the piezoceramic legs in detail, the actuator is built like a bimorph (Figure 1). Left and right side of the leg can be independently activated (0-48V). When energized, the leg can extend and bend a few microns. The tip of the leg (i.e. the friction drive pad) can move to any point within the rhombic area as illustrated in Figure 1. When the leg is not energized, the tip of the leg will be at point a. When only activating one side of the leg, it will bend to the left or to the right (b or d respectively). With both sides of the leg fully activated, it will extend to its maximum height (at point c). A Piezo LEGS motor will have several actuator legs working together. The motion of the motor will be dependent of the input electrical waveform signals. To achieve motion, two legs (or more) are driven in parallel. In total, each motor will need four separate control signals. Each leg, however, is controlled with two voltages. In Figure 2 two different waveforms are depicted. Rhomb is a rudimentary waveform which will make the tip of the leg move in a rhombic pattern. A more advanced waveform is called Delta. The Delta waveform is optimized for smoothest walking, and is best for high precision positioning.

For each waveform period the leg will complete one revolution; it will take a full step, also defined as a waveform-step (wfm-step). With fine control of the generated waveform, it is possible to divide the full wfm-step in to smaller increments; so called microsteps. The movement of individual legs is almost linear with the applied voltage. The piezo actuator leg is an analog component, and will move approximately 50 pm/mV. In other words, if the microstep voltage is controlled on mV level, the resolution of incremental motion is ~50 picometers (50•10-12 m). For practical reasons we have limited our standard microstepping drive electronics to microsteps of nanometer size (1•10-9 m). The piezo actuator legs can be regarded as pure capacitors. To hold the legs in a given position you need to keep the voltage stable. At stand still there is no power draw or heat generation in the piezo. When holding position the motor can respond instantaneous and compensate the slightest deviation by taking nanometer sized microsteps. The amount of energy consumed by the Piezo LEGS depends on the size of the motor. For example, the linear 6 N motor consumes only 5 mW per wfm-step, of which ≤10% is lost as heat in the piezo. Like other ceramic capacitors the piezo actuator is temperature dependent; capacitance is increasing with temperature. Increase in temperature can be due to ambient changes or operation of the motor. Consequently, with increased temperature the motor will consume more power and put a higher capacitive load on the driver amplifier.
CUSTOMIZED ELECTRONICS
PMD104
In many applications, it is advantageous for users to integrate the drive electronics into their own system. PiezoMotor is fully open with information about how to control the motion of Piezo LEGS, and will support those who decide to make customized electronics. We do however encourage customers to start using our motors with drivers/ controllers supplied by us. Standard drive electronics are available for Piezo LEGS motors both from PiezoMotor as well as from independent suppliers. They range from very simple and low cost to very advanced. See our web page for guidance or contact us for recommendations.
SENSOR Many Piezo LEGS applications will require position sensors/encoders. We will help you make the correct choice. Sensors that fit our motors are available in standard as well as custom version from several independent suppliers. If you want the sensors integrated at the factory, just contact us for further assistance.

Motor Characteristics Piezo LEGS® linear and rotary motors positions down to nanometer range if required. We talk about taking steps but in a different way from traditional stepper motors.
EXAMPLE LT20 motor, no load, 2000 wfm-steps per second Waveform Rhomb: ~5 µm x 2 kHz = ~10 mm/s Waveform Delta: ~3.5 µm x 2 kHz = ~7 mm/s EXAMPLE LT20 motor, 10 N load, 2000 wfm-steps per second Waveform Rhomb: ~4 µm x 2 kHz = ~8 mm/s Waveform Delta: ~2.5 µm x 2 kHz = ~5 mm/s Fine positioning is achieved through dividing the wfm-step into discrete points; so called microsteps. The resolution will be a combination of the number of points in the waveform and the external load. For example, a full wfm-step of 4 µm can be divided into 8192 microsteps that are only ~0.0005 µm (~0.5 nm). The resolution of the motor is all dependent of the electronics and how well they can manage the discrete voltage levels of the waveform.

WFM-STEP LENGTH [µm]
In this catalogue you will find detailed information about the standard products from PiezoMotor. Piezo LEGS are non-resonant walking motors; in several aspects quite different from DC or stepper motors. A Piezo LEGS motor is friction based, meaning the motion is transferred through contact friction between the drive leg and the drive rod/disc. You cannot rely on each step being equal to the next. This is especially true if the motor is operated under varying loads. For each waveform cycle of the drive signal, the motor will take one full step, referred to as a waveform-step (wfm-step). There is dependence between external load on motor and wfm-step length. When external load is high the wfm-step length is reduced. For example, see performance curve of LT20 type motor in Figure 3. At zero external load the typical wfm-step length is ~5 µm, but as load is increased the wfm-step length is shortened one or a few microns when working against load. In opposite, and not shown in diagram, the wfm-step length will be increased one or a few microns when working with load. It should be noted that the wfm-step length will also depend on internal piezo temperature, and on the type of waveform. The wfm-step length, as described above, can be used to calculate the approximate motor speed. Wfm-step length at a given load is multiplied with the frequency of the drive signal waveform.

Glossary WFM-STEP Waveform-step; the step taken for one full waveform period. Step size is load and temperature dependent. Typical load dependence curve is given for each motor.
MICROSTEP An incremental step within the full wfm-step. The size of the microstep will give the resolution of the motor. For a linear motor the microstep can be sub-nanometer.
WAVEFORM The shape and form of the electrical signals which controls the Piezo LEGS. Waveform Rhomb and Delta are commonly used, and will give different behavior in terms of speed, microstepping performance etc.
STEP LENGTH Linear travel, specified for full wfm-steps in load dependence curve. In specification tables the value is also given for a single microstep.
STEP ANGLE Rotary motion, angular displacement for full wfm-step in load dependence curve. In specification tables the value is also given for a single microstep.
RESOLUTION The piezo actuator legs are analog components which bend to move the drive rod or to rotate the drive disc. Resolution depends only on how well you control the voltage levels of the control signals. It is never difficult to get extreme resolution with the Piezo LEGS.
RECOMMENDED OPERATING RANGE The range of external load recommended for best microstepping performance and life time. Motor will handle higher loads, but the linearity within the wfm-step is impaired.

Fast speed and quick response time, as well as long service life are other benefits. In combination with the micro radian resolution the technology is quite unique. The motor is ideally suited for move and hold applications or for automatic adjustments. When in hold position it does not consume any power. Drive technology is direct, meaning no gears are needed to create motion. The motor has no mechanical play or backlash.
Motor comes with an integrated high resolution magnetic encoder. Feedback from the encoder gives resolution of 0.2 mrad (0.01º) in closed loop operation. Open loop resolution of the motor is 0.1 µrad (0.000006º).

Encoder LR17 has an integrated magnetic absolute encoder. It gives 15 bit SSI data. SCK (Sensor Clock) and SDA (Sensor Data) are normally at high level (idle). When receiving a clock pulse from the controller, the LR17 will respond with position data. The SCK frequency should be 70-180 kHz. Data should be read shortly before the positive flank. The time-out between positive flanks is 20-30 µs. Part No The output data is 15 bits (msb first), followed by a stop bit. If SCK continues beyond the stop bit, there will be a second stop bit followed by repeated 15 bit Name data and a stop bit. A minimum of 120 µs is needed after position readout to ensure refresh of position data. Reading position every 0.5 ms is the maximum recommended rate for continuous operation.

PiezoMotor速 Driver PMCM21
PiezoMotorÂŽ Driver PMCM21
Easy to use Analog control Low power consumption Small size
PMCM21 is a simple hand-held push-button driver for Piezo LEGS motors (linear and rotary) that offers sub-micron resolution linear motion. Pushing the button to move in one direction ramps up speed by utilizing phase-shifting of the drive signal. Maximum speed, determined by the size of the motor (capacitive load) is generally in the few millimeters per second range. A quick press of the button generates sub-micron steps. Positioning below 0.1 Âľm is possible by altering direction.

Functional principle The driver controls the Piezo LEGS motor by feeding waveform signals which elongates and bends each of the piezo drive legs. The waveforms are specially designed to make the motor drive legs perform a precise walking motion. The motion of the drive legs is transferred via friction contact to a linear rod or to a rotary disc. For each waveform cycle the Piezo LEGS motor will take steps, by definition called waveformsteps (wfmâ&#x20AC;&#x2018;steps). The wfmâ&#x20AC;&#x2018;step length is load dependant and also depends on the signal phase shift. With maximum phaseshift (90Ë&#x161;) the step size is in the range of a few

4,5
micrometers for a linear Piezo LEGS motor. Rotary Piezo LEGS motors have their drive legs working on the perimeter of a drive disc. The wfm-step angle depends on the diameter of the rotary motor but is usually less than one milliradian. The maximum step length (and hence the speed) is reduced by internal phase shifting of the waveform signal, and fine positioning is performed through analog bending of the drive legs. The user of the PMCM31 driver will only need to change the control signal voltage level in order to go from full step size down to high precision positioning.

PMD101 is a 1-axis driver for use with Piezo LEGS motors from PiezoMotor. It is one of the more advanced drivers in the product range giving the Piezo LEGS motors resolution down in the nanometer/microradian range. Driving the motors in closed loop is possible when reading back position from an positional sensor. PMD101 supports quadrature encoders, and serial SSi sensors. Issuing a single command will guide the motor to the exact encoder count, taking in to account the parameter settings for ramping behavior.

Waveforms are specially designed to make the drive legs perform a precise walking motion. Motion of the drive legs is transferred via friction contact to a linear rod or to a rotary disc. For each waveform cycle the Piezo LEGS motor will take one full step, by definition called a waveform-step (wfm‑step). The wfm‑step length is load dependant but in the range of a few micrometers for a linear Piezo LEGS motor. Rotary Piezo LEGS motors have their drive legs working on the perimeter of a drive disc. The wfm-step angle depends on the diameter of the rotary motor but is usually less than one milliradian. Generated signal waveform is made up of a large number of voltage target points in time. Each small voltage change will move the motor only by a fraction of a wfm-step, defined as a

microstep. PMD101 driver gives a maximum resolution of 2048 microsteps per full wfmstep. One microstep with highest resolution settings equals ~2 nanometer (0.002 µm) of linear motion, or ~0.5 microradian of angular motion.
Working with the driver PMD101 communicates with the host (PC) via USB. Communication with the driver is through a protocol language (ASCII commands). User can run in closed loop target mode, or in open loop mode, with full access to set resolution, step frequency (speed) etc. Positional sensors are used to keep track of the precise position of the Piezo LEGS motors. The driver can read limit switches and reset at index. Ramping parameters are set to prevent overshooting when closing in on target in closed loop operation. The PMD101 is a full featured driver for demanding applications.

Linear Encoders
Non-contact optical encoders Quadrature interface – A/B and index Compatible with all PiezoMotor microstepping drivers
Piezo LEGS linear motors are capable of extreme resolution, down to the sub-nanometer range. Position encoders are required to build a system with high repeatability and accuracy. PiezoMotor offers linear encoders from Renishaw® and from MicroE Systems®. Both companies are supplying very high quality, top of the line encoders. Encoders of two different resolutions from each company are kept in stock at PiezoMotor. They are offered as an add-on to the motor purchase, complete with cables, instructions, drawings and CAD files, giving the customer an easy integration. Common features to all encoders:
Selection
Installation Guideline
With high resolution motors it is important to exercise great care in selecting the appropriate encoder, and even more important – the correct encoder location. The rule of thumb is to place the encoder as close as possible to the point of interest. This will minimize issues like thermal drift in the mechanical structure. Experts at PiezoMotor are available regarding design and selection questions.
System design
In a closed loop system, the motor, encoder and driver act together to move an object to a given target position. Accuracy of the position is given by the accuracy of the sensor. With the high resolution motor, Piezo LEGS, it is possible to regulate to a position within ±1 sensor count. The total system accuracy is depending on where the sensor is mounted, how it is mounted and of course the mechanical stability and thermal behavior of the complete assembly.
To make a complete closed loop motion system a number of key components are required:
Mechanical Installation
Piezo LEGS linear motor Piezo LEGS microstep driver Linear guide (roller bearing) Encoder Scale, with/without index mark Cabling
Links to the manufacturer manuals can be found at www.piezomotor.com. The documentation provides information about the correct mounting of the encoder and encoder scale. The mechanical design and the location of the sensor is very important. For example, 10 mm of steel (with thermal expansion coefficient of 12·10-6 ºC-1) located between the sensor position and the position of interest will introduce an error due to thermal drift of 1.2 µm for a 10°C temperature change.
87
With a high resolution Piezo LEGS motor, it is possible to continuously operate in closed loop correcting for thermal changes in other parts of the structure, but one must be able to rely on the encoder readout. All of the encoders discussed here are incremental encoders. They are only giving counting pulses of the encoder resolution when moving. To have an absolute position we need to find a known position where the position is set to zero, or to a desired value. Movement away from this position will then be counted by the driver and the position will be continuously updated. An absolute reference point can be found by the encoder if the scale is equipped with an index mark. The driver can search for the index mark and reset the position when it is encountered.
Electrical Installation The supplier manuals provide information about the correct installation from an electrical point of view. Moving at 10 mm/s with a 5 nm sensor will give 2Â MHz pulses from the encoder. This is a fairly high frequency and the wiring should be made according to the instructions in the supplier manuals. The different parts of the system must be grounded properly. For a complex system with multiple sources of electrical noise, finding the correct grounding may require testing of several solutions.
88
Encoders are designed to work with a specified supply voltage. Due to power consumption there can be a voltage drop in the wiring to the encoder. This is more likely to occur when operating a high resolution encoder at high speed. Maximum counting frequency of the encoder should be set lower than the maximum counting frequency of the driver. This is to ensure that counting pulses are counted correctly in the driver and that no pulses are lost. Keep in mind that the instantaneous speed can be higher than the average speed.
Operation The motor driving direction and the encoder counting direction can be switched in a particular design. The Motion System software from PiezoMotor will verify this when a new system is setup. If a different software package is used the user must set the direction parameters separately before using the system in closed loop. See the driver manual for details. Failure to set the parameter will result in movement to limit in one direction.

Installation Guidelines for LL and LT motors
Installation Guidelines for LL and LT motors
The Piezo LEGS is a high precision motor. A few simple instructions must be followed in order to get the best performance and lifetime. If the motor is installed poorly both performance as well as life time is severely affected.
Piezo LEGS® Linear 6N
Piezo LEGS® Linear Twin 20N Drive legs - piezo actuators
PRELOAD
Drive rod
Mechanical adapter with sheet metal extender
The Piezo LEGS is a direct drive motor. Proper friction coupling between drive legs and drive rod is essential for optimum performance. When properly installed the motor can position down to the nanometer range without backlash.
Mechanical Notes The motor drive rod must not be subjected to non-axial force – even small loads or torques on the end of the drive rod may cause loss of proper friction contact between drive legs and drive rod. The motor function can be impaired and the motor can be damaged.

Always mount using a mechanical adapter with flexible sheet metal extender so that transverse loads and torques on the drive rod are minimized. Never directly connect the drive rod and moving part in your application (for example when connecting the motor to a linear bearing). Mounting directly will introduce loads large enough for the drive rod to loose proper friction contact.
✘NO

Installation Guidelines for LL and LT motors
Always align the drive rod so that there are no loads transverse the drive rod axis of motion. Even small angular misalignment may impair motor function.
✔YES
✘NO F
Misalignments in the drive plane are less critical but should be avoided. If the drive rod is aligned poorly there is risk for contact between drive rod and motor housing. Contact may impair function.
✔YES
✘NO
If a mechanical adapter with metal sheet extender cannot be used because of space limitations, we suggest the motor work against a spring loaded linear bearing. Small non axial loads can be reduced by pressing against a spherical surface. Note that angular misalignments may generate non-axial loads resulting in impaired function.
✔YES
✘NO FS

93
Installation Guidelines for LL and LT motors
If acceptable, insert a thin piece of hard rubber between drive rod and stage block to remove vibrations.
The drive rod must not be removed from the motor, and it must not be moved to a position where contact with any drive leg is lost. The drive legs can be severely damaged if they are not preloaded while motor is running. Repositioning a drive rod that has come out of place may crack the ceramic drive legs. Contact PiezoMotor for instructions on how to reposition the drive rod.
â&#x153;&#x2DC;NO
Electrical Notes The maximum voltage of +48 V relative to GND must never be exceeded. Overvoltage or reverse polarities can damage the motor. Be careful not to overheat motor! Continuous operation at higher drive frequencies may damage the motor. In non-continuous applications higher drive frequencies may be tolerated, but please consult PiezoMotor in these cases. Twin configured motors must be connected with two motor cables. The two sides of a twin configured motors are run in parallel. Use a Twin Connect Board for proper wiring. When using PiezoMotor drivers, be sure to check driver data sheet or manual for notes on maximum drive frequency for different capacitive loads.
