ELL14 Motorized SM1 Optic Rotator Chapter 4: Operation Chapter 4 Operation Getting Started Caution Although the module can tolerate up to 8 kV of air discharge, it must be treated as an ESD sensitive device. When handling the device, anti-static precautions must be taken and suitable anti-discharge appliances must be worn. - Page 9 ELL14 Motorized SM1 Optic Rotator Chapter 4: Operation Controlling the Rotator The rotator 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.

- Page 14 ELL14 Motorized SM1 Optic Rotator Chapter 4: Operation 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.

ELL14 Motorized SM1 Optic Rotator Chapter 5: Troubleshooting and FAQ Chapter 5 Troubleshooting and FAQ Frequently Asked Questions Rotator not moving Check power supply lines ratings (polarity, voltage drop or range, available current) or reduce cable length. Check module is not in boot loader mode (power cycle the module to exit boot loader). Current consumption must be higher than 36 mA at 5 V. - Page 16 What is the typical product life time? ELL14 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.
