Control
There are multiple options for powering, driving, and controlling ELL8 rotation stage, which are detailed in the Positioning the Rotation Stage section of the
Operation tab. Each stage possesses a 3.3 V serial bus and is designed to be operated with or without the interface board; the Pin Diagram tab provides pin
assignments. Thorlabs offers software for our Elliptec products capable of providing full and independent control of the stage. When the interface board is used
as an accessory to change the position of the stage, its status in the software is automatically updated. Please note that the ELL8 rotation stage is not
designed for continuous operation. We recommend operation with duty cycles of 40% or less.
The multi-drop communications bus offers the option of connecting the stage to a hybrid network of up to 16 Elliptec resonant motor products and controlling
the connected units with a device such as a microprocessor. When multiple units are connected to the same interface board, all can be controlled
simultaneously using either the software or the buttons on the interface board.
Application Idea
The rotation stage is well-suited for integration into a variety of applications. In the setup pictured at the top of this page, and detailed below, the rotation stage
enables wavelength selection by controlling the angle between a diffraction grating and a slit.

Handling
The ELL8K(/M) rotation stage and interface board components are robust to general handling. To ensure reliable operation,
keep the surface of the plastic track contacted by the motors free of oils, dirt, and dust. It is not necessary to wear gloves
while handling the rotation stage, but avoid touching the track to keep it free of oils from fingerprints. If it is necessary to clean
the track, it may be wiped with isopropyl alcohol or mineral spirits (white spirit). Do not use acetone, as this solvent will
damage the plastic track.
The open frame format of the ELL8K(/M) can tolerate up to 8 kV of static discharge. ESD precautions should be taken, as an
electrostatic discharge can produce an electrical signal that may cause an unintended movement of the stage. A bending load
in excess of 500 g applied to the board may cause the PCB to deform, which will degrade the
performance of the rotation stage. As readings from a magnetic sensor are used during the
homing and positioning of the stage, avoid subjecting the structural PCB to excessive loads or
magnetic fields. Limit the strength of magnetic fields in proximity to the magnetic sensor to ±5
mT to avoid negatively affecting the homing and positioning operations.
Mounting and Loading the Rotation Stage
The ELL8(/M) rotation stage should be mounted so that the top surface of the stage is in the
horizontal plane. There are four Ø0.17" (Ø4.2 mm) through holes located along the edges of the board, which are visible in
the image at the center-right of this tab, that may be used to mount the stage with or without the mounting brackets. The
two brackets included in the ELL8K(/M) bundle have slots that accommodate 1/4"-20 (M6) cap screws to facilitate
mounting the stage to breadboards and optical tables. The brackets possess 6-32 (M3) tapped holes aligned with
the four through holes in the board. Attach the brackets on either side of the stage, as pictured at right, so that
they extend out from and span the left and right sides of the board. Do not attach the brackets so that they cross
the back of the board, as metal brackets in contact with the electronics may cause electrical shorts detrimental to
the operation of the stage. When mounting the stage, ensure that the installation does not bend the PCB.
Loads may be mounted to the stage using the 37 tapped holes for 8-32 (Imperial Version) or M4 (Metric Version) threaded screws, whose spacing is shown in
the diagram below and in the diagrams included in the Specs tab. The maximum allowed weight of the mounted components is 200 g. In all cases of mounting
and loading, ensure that nothing interferes with the moving parts of the rotation stage.
Supplying Power
When the setup includes the interface board, power may be supplied through the Micro-B USB connector and/or the 5 VDC power socket located on the
board. The electronics on the interface board convert the applied DC signal to a sinusoidal signal oscillating at the required resonance frequency.
The ELL8K(/M) bundles include a 5 VDC power supply whose connector mates with the power socket on the interface board. Delivering power through this
socket also leaves the Micro-B USB connector available to accept a USB cable connection to a computer, which can be used to control the stage remotely.
The power supplied by the computer through the USB 2.0 connection is not sufficient to power the stage. If computer control is not necessary, another option
for supplying power to the stage is a portable USB 5 V battery pack connected to the Micro-B USB connector on the interface board.
When the implementation does not include the interface board, the connection with the power source is made using the pins on the Picoflex connector that is
included on the rotation stage board. A pinout diagram of this connector is included in the Pin Diagram tab, and information on powering and addressing the
rotation stage is given in the manual and the communications protocol manual, respectively.
Operation of the Motors
The motion of the ELL8(/M) stage is controlled by forcing the piezoelectric elements to vibrate at specific ultrasonic frequencies. For each motor, there is one
ultrasonic resonant frequency that will push the stage forward, and another that will pull the stage backward. Operating a motor at one of its resonance
frequencies causes the tip of the motor to continuously cycle in a tight clockwise elliptical path. When the motor is driven at its other resonant frequency, the
tip of the motor cycles through that same path in a counterclockwise direction. Both resonant frequencies are around 100 kHz. The total displacement at the tip
of motor is a function of the mechanical load it is driving and the voltage supplied to the piezo element. In the case of no loading and a 5 V maximum driving
voltage at a resonant frequency, the tip of the motor expands and contracts no more than a few microns while tracing the elliptical path. Please see The
Elliptec™ Motor tab for more information and an animation illustrating the operational principle of the motors.
Homing the Rotation Stage
To Home the stage, press the BW button on the interface board, click the Home button in the Elliptec software's graphical user interface (GUI), or send the
Hide The Elliptec™ Motor
appropriate ASCII message as is specified in the communications protocol manual.
The default Home position is referenced to a fixed feature on the stage assembly. If desired, the user may redefine the position of Home to be offset from the
default position by up to +90° (a quarter turn in the clockwise direction). Being able to customize the Home position can be useful when synchronizing the
orientations of two or more stages. When executing the Home command, the stage first finds the approximate location of Home, and then a fine-positioning
procedure is used to orient the stage at Home with an accuracy of 288.0 µrad. The user can specify whether the stage rotates in a clockwise or
counterclockwise direction (as defined from the perspective of looking down on the surface of the stage) during the first phase of the homing procedure, but
the fine-positioning phase is always performed in the counterclockwise direction for repeatability.
The default Home position is found by using first an optical IR sensor and then a relative (incremental) magnetic sensor. The optical sensor is located under
the stage, and its 980 nm emission is confined by the underside of the stage and the top surface of the PCB. The magnetic sensor's encoder is connected to a
shaft that revolves 64 times for each rotation of the stage. The encoder generates one command pulse for each revolution of the shaft, which results in 64
command pulses being generated for each rotation of the stage, effectively defining 64 sectors within a full rotation. Each sector consists of 4096 individual
increments. Using the output of the magnetic sensor alone, it is not possible to uniquely identify any of the 64 sectors defined by the encoder. Accurate
positioning of the stage requires referencing the readings from the magnetic sensor to a known location, and the IR sensor signal is used to establish the
required reference point. At the start of the procedure to find the default Home position, the stage is rotated and the signal from the IR sensor is monitored.
The IR sensor's detection of the fixed feature on the stage assembly triggers the rotation stage assembly to start monitoring the signal from the magnetic
sensor. The stage continues to rotate until it detects the first subsequent command pulse generated by the magnetic sensor's encoder. The location
corresponding to this command pulse is defined as the default Home position. If the user specifies the position of Home to be offset from the default Home
position, the offset is applied in the clockwise direction. After the Home position is found, readings from the magnetic sensor, which can resolve angular
increments of 24.0 µrad, are used to position the stage and when executing the Home command.
Positioning the Rotation Stage
Note that the rotation stage is not intended for continuous operation. We recommend operation with duty cycles of less than 40% during general use, while
operation with duty cycles greater than 60% should be limited to a few seconds.
Before the stage may be positioned, the Home position of the stage must be found. Please see the previous section for details. The movement of the stage
may be controlled by pressing buttons on the interface board, through computer control via the Elliptec™ software package that may be downloaded, or by
sending simple signals to digital lines on the stage's board. The buttons on the interface board can be seen in the image of the interface board above. A link
to download the software and accompanying documentation can be found in the Software tab. The interface board may be used as an accessory while
interfacing with the stage through the Elliptec software; all changes in the position of the rotation stage that occur as a result of pressing buttons on the
interface board are registered by the software, and the software may independently control the rotation stage while the interface board is connected. It is also
possible to effect the simultaneous movement of several rotation stages by connecting all to the communications bus. When this is done, the software can
send separate commands to each stage, while commands originating from buttons pressed on the handset will be sent to all connected stages. The
communications protocol manual describes how to use the software to individually address each connected stage.
The interface board can be used to move the stage forward and backward in increments by pressing and holding the JOG button while pressing and releasing
the FW or BW button, respectively. The default increment is 45°, and a custom increment can be set using the Elliptec software or by sending the appropriate
ASCII message(s) as specified in the communications protocol manual. The Elliptec software can be used to move the stage to absolute and relative positions,
in addition to jogging the stage forward or backward. The software is also used to set the jog step size, read the position of the stage, and adjust the position
of Home, as is described in the previous section.
Readings from the magnetic sensor, which can resolve angular increments of 24.0 µrad, are used to position the stage and when executing the Home
command. The travel range of the stage is not limited, but the reported orientation of the stage is always expressed as a value between 0° and 359.99°. The
minimum incremental movement of the stage is 288.0 µrad, and it can be positioned with a repeatability of 434 µrad in response to signals from the magnetic
sensor.
The stage learns to efficiently position itself precisely using a position error compensation algorithm. After the stage moves into a new position, it detects the
error between the requested and actual positions. The position of the stage is then corrected, and an error compensation value is calculated. The algorithm is
then updated with the error compensation value, so that it is applied when the stage is move to its next position. Typically, an optimum error compensation
value is found after between two and six movements.
Resonance Frequencies
On power-up, the factory default setting instructs each motor driving the rotation stage to search for the resonance frequencies that will deliver the best
performance. During this process, the rotation stage will translate a forward and backward by a small amount. If movement on start-up is undesirable, it is
possible to disable this calibration procedure by using the serial port to initialize the frequencies on power-up. A new search for optimal resonance frequencies
may be performed at any time; to maintain optimal performance, it is recommended that new searches be performed after changes in loading and/or ambient
temperature. Please see Section 3.3 of the manual for details.

The Components of the
Elliptec Motor
Click to Enlarge
The Elliptec Piezoelectric
Resonant Motor
Elliptec motors quickly and precisely position stages and mounts while never seeming to move. Their
microscopic movements occur at ultrasonic frequencies and are invisible to the naked eye.
The Elliptec™ Piezoelectric Resonant Motor
Thorlabs' Elliptec™ piezo resonant motor, shown at right, is lightweight, with a mass of 1.2 g,
and compact: the dimensions of the resonator housing, excluding the spring, are 8 mm x 4
mm x 20 mm.
Components of the Motor
The components that compose the motor are shown at far-right. The piezoelectric element is press fit into the aluminum
resonator, which has been precisely designed and machined to produce the desired elliptical motion at the tip and to interface optimally with the driven
module. The free ends of the spring are integrated with the resonator housing. The wires, which are soldered to the top and bottom of the piezoelectric
element, deliver the voltage signal that induces the piezoelectric element to vibrate at ultrasonic frequencies.
When the motor is built into a system, the open loop of the spring is bolted to a sturdy surface that is stationary with respect to the item to be driven, and the
tip of the resonator is placed in contact with the item. The purpose of the spring is to maintain constant contact between the tip of the resonator and the driven
item, and the direction of motion is determined by the resonance frequency at which the piezo element is driven.
Elliptical Motion and Comparison with Conventional Motors
The motor is operated by driving it at one of its two
resonance frequencies. A voltage signal oscillating
at an ultrasonic frequency is applied to the
piezoelectric chip, which responds by expanding
less than a micron and then contracting back to its
original dimensions at the frequency of the driving
signal. This rapid-cycling change in the chip's
dimensions causes a vibration in the aluminum
resonator housing. When the vibration is at one of
the housing's resonance frequencies, a pushing
motion results at the tip of the motor. When
the vibration is at the other resonance frequency a
pulling motion results.
As illustrated in the video, the pulling and pushing
motions result from the tip of the motor tracing an
elliptical path in space when the motor operates at
resonance. The selected resonance frequency
controls the direction of the cyclical motion. The
motor's tip traces one half of the ellipse as it
expands and the other half as it contracts. When
the motor pushes the driven item, the motor's tip is in contact with the item while the tip expands; the two are not in contact while the tip contracts. The
converse is true when the motor pulls the driven item in the opposite direction. The total displacement at the tip of the motor is a function of both the
mechanical load it is driving and the voltage supplied to the piezo element. The maximum displacement can be up to a few microns when the peak driving
voltage is 5 V.
The motor behaves in many ways like a DC or electromagnetic stepper motor, but it does not suffer from many of the drawbacks of these conventional motors.
Unlike conventional electromagnetic motors, which must overcome inertial delays to come to a stop, the highly dynamic Elliptec motor can stop within
microseconds. As it has no gears, it does not exhibit backlash. Since it possesses no magnets, it is compatible with use in environments sensitive to
electromagnetic interference. The motion of the driven element is continuous and smooth. As the tip of the motor must be in contact with the driven item to
induce motion, the motor possesses the safety feature of an inherent friction brake. When in contact with a plastic surface, the motor operates virtually silently.
For OEM applications, the motor can be manufactured in volume at low cost, and it can be driven by inexpensive analog electronics. It does not require
microprocessors or software; however it is compatible for use with them.

rotation occurs when one motor pushes the track forward while the other pulls it backward.
