Page 3: Chapter 1 Introduction
Chapter 1 Introduction The ELL18 Rotation Stage is part of the Thorlabs series of resonant piezo motor circuits and bare modules for OEM applications. The resonant piezo design of these motors offers fast response times and precise positioning, and are therefore particularly useful in scanning applications. -

ELL18K Rotation Stage Evaluation Kit Chapter 3: Description Chapter 3 Description 3.1. Environmental Conditions Warning Operation outside the following environmental limits may adversely affect operator safety. Location Indoor use only Maximum altitude 2000 m Temperature range 15°C to 40°C Maximum Humidity Less than 80% RH (non-condensing) at 31°C To ensure reliable operation the unit should not be exposed to corrosive agents or excessive moisture, heat or dust. -
Page 6: Mounting
Do not allow the wires to contact other moving parts. The recommended mounting orientation is horizontal. Two mounting brackets are shipped with the ELL18K/M kit to allow mounting to a standard 1” or 25 mm pitch optical table or breadboard. Figure 1 ELL18 rotation stage Page 4 DTN000524-D02... - Page 7 The image below shows a diffraction grating mounted on the stage, with the diffracted light being incident on the slit located to the right. Figure 2 ELL18 with components fitted Figure 3 Fixing the ELL18K to the work surface 1. Using the M3 x 6 mm (6-32 x ¼”) bolts supplied, fix the mounting brackets to the circuit board as shown above.

Page 8: Chapter 4 Operation
ELL18K Rotation Stage Evaluation Kit Chapter 4: Operation Chapter 4 Operation 4.1. Getting Started Caution Although the module can tolerate up to 8kV of air discharge, it must be treated as ESD sensitive device. When handling the device, anti-static precautions must be taken and suitable anti-discharge appliances must be worn. Do not expose the stage to magnetic fields as this could affect the positioning and homing sensor operation. -
Page 9: Controlling The Stage
ELL18K Rotation Stage Evaluation Kit Chapter 4: Operation 4.2. Controlling the Stage The stage can be controlled in three ways; via the handset, by the Elliptec software running on a PC, or by writing a custom application using the messages described in the communications protocol document. Homing and Jogging functionality can also be accessed by applying voltages to the digital lines on Connector J1. -

ELL18K Rotation Stage Evaluation Kit Chapter 4: Operation 4.2.1. Hand-held Controller Caution On power up the stage will move while the unit checks the sensors and then searches for the home position. The hand-held controller supplied with the ELL18K Evaluation Kit features two buttons (marked FW and BW) that allow control of the stage position. -

Page 14: Frequency Search
ELL18K Rotation Stage Evaluation Kit Chapter 4: Operation 4.3. Frequency Search Due to load, build tolerances and other mechanical variances, the default resonating frequency of a particular motor may not be that which delivers best performance. A frequency search can be performed using the Main GUI Settings panel in the ELLO software, or by using the serial communication line (SEARCHFREQ_MOTORX message), which offers a way to optimize the operating frequencies for backward and forward movement. -

ELL18K Rotation Stage Evaluation Kit Chapter 5: Troubleshooting and FAQ Chapter 5 Troubleshooting and FAQ 5.1. Frequently Asked Questions Stage is moving back and forth after power up If the digital line “bw” is driven low before powering up the stage, the module will go into calibration mode. Remove power to exit calibration mode. - Page 16 What is the typical product life time? ELL18 product life time is restricted by the wearing of moving surfaces and the motor contact as motion is started (due to resonance build up) and performed (due to friction), and is expressed in km travelled. Lifetime will depend on several factors (e.g.
