Digital positioning controller enables real-time positioning of synchronized multi-axis systems
April 30, 2012 // Julien Happich
The digital positioning controller EPOS3 70/10 EtherCAT from Maxon Motor meets the highest demands in real-time positioning of synchronized multi-axis systems.
Extremely compact in size, the EPOS3 possesses a wide nominal power supply voltage range from 11 to 70 VDC and delivers a continuous output current of 10 A, during acceleration and deceleration even up to 25 A. Designed for DC and EC motors with a power range up to 700 Watt, it provides outstanding uniform running for motors equipped with incremental encoders. The EPOS3 70/10 EtherCAT easily integrates as slave into real-time EtherCAT protocol-based Ethernet networks, and, with the provided device description file and device-specific configuration guide. A multitude of operating modes allows efficient, flexible use in a wide range of drive systems in robotics, automation, and mechatronics. The positioning controller supports a broad bandwidth of encoders.
In the typical EtherCAT modes "Cyclic Synchronous Position (CSP)", «Cyclic Synchronous Velocity (CSV)», and «Cyclic Synchronous Torque (CST)», the EtherCAT master calculates the trajectory points and sends the target parameters cyclically and synchronous via EtherCAT network to the EPOS3. A bundle of additional features, such as speed control with given target velocity in «Profile Velocity Mode (PVM)», «Homing» to a defined mechanical position using numerous implemented methods is available. The same applies for the generous number of inputs and outputs, which makes the extra EtherCAT I/O module obsolete.
Digital inputs/outputs (11/5) can be configured as reference or limit switch as well as Capture or Trigger, or can be used to activate holding brakes with definable ON/OFF switching delays. Additionally, analog inputs/outputs (2/1) are at free disposal. Perfectly tailored for servo motors, the EPOS3 70/10 EtherCAT offers likewise built-in motor filters with motor chokes for EMC-conform operation. Prefabricated cables and perfectly matching accessories help to make installation and commissioning easy. The controller offers comprehensive circuitry against overcurrent, excess temperature, undervoltage and overvoltage, against voltage transients and against short-circuits in the motor cable. Furthermore, it is equipped with adjustable current limitation to protect motor and load as well as protected digital inputs and outputs.
The «EPOS Studio» serves as user interface for efficient parameterization employing a lot of smart and clever functions and intuitively designed Wizards. Tasks, such as, Firmware download, automatic controller commissioning, I/O configuration, test & data recording becomes little more than child's play. Alternatively to the Ethernet interface, a USB 2.0 port is available for commissioning and diagnostics.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
