- Page 3 Chapter 1 Safety For the continuing safety of the operators of this equipment, and the protection of the equipment itself, the operator should take note of the Warnings, Cautions and Notes throughout this handbook and, where visible, on the product itself. SHOCK WARNING Given when there is a risk of electric shock.
- Page 4 2.1. Introduction The ELL8 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.
- Page 5 Do not allow the wires to contact other moving parts. The recommended mounting orientation is horizontal. Two mounting brackets are shipped with the ELL8K kit to allow mounting to a standard 1” or 25 mm pitch optical table or breadboard.

- Page 8 ELL8K Rotation Stage Evaluation Kit Chapter 3: Operation 3.2. Controlling the Stage The stage can be controlled in three ways; via the handset, by the Elliptic 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.
- Page 9 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 ELL8K Evaluation Kit features two buttons (marked FW and BW) that allow control of the stage position. The handset also provides for connection to the host PC and to the external 5V power supply.
- Page 10 3.2.2. Software Control When connected to the host PC, the stage can be controlled remotely, via the Elliptec software. 1. Download the Elliptic software from the downloads section at www.thorlabs.com. Double click the saved .exe file and follow the on-screen instructions.
