Nanopositioning Controller

PI L.P. (Auburn, MA) has introduced the E-709 digital piezo nanopositioning controller that features fifth order polynomial digital linearization, two notch filters for piezo operation at high frequencies, and DAC-in-the-loop architecture for positional stability. High-speed interfaces include USB, RS-232, Real-Time Analog, and TTL. Setup software enables remote access and servo tuning. The controller includes a piezo power amplifier, and can be used in applications providing analog control signals.

Rail Brakes

RB Series Generation II linear profile guide rail brakes from Nexen Group (Vadnais Heights, MN) are designed for stopping and holding in e-stop and power-off situations. Each rail brake clamps directly onto the center of the guide rail to provide positive braking and holding on all axes, with no effect on the bearing surfaces. The field-adjustable friction facing contact area minimizes rail wear. No lubrication or periodic maintenance is required, and the brakes fit most popular profile guide rails. Other features include low backlash, brake geometry similar to linear bearing cassettes, large clearance area between the brake and rail, and static holding cycle life in excess of one million cycles.

Motor Control Platform

XMOS (Sunnyvale, CA) has released a motor control platform that contains XCore® processors, an XMOS motor control hardware board with support for dual axis motor control and communication, and a suite of control, processing, and interfacing functions to help designers develop motor drives in high-level software programming languages. The XCore processor architecture, combined with the XTA static timing analysis tool, provides a programmable platform, which executes software without requiring an RTOS. The XS1-L1 500 MIPS processor handles three-phase BLDC motor control loops, while the XS1-L2 1000 MIPS processor manages communication, logging, and motion control.

Vision-Guided Motion Controller

A pocket-sized, vision-guided motion controller from Precise Automation (San Jose, CA) is based on a distributed network architecture that allows the device to be located at the point of use. Along with standard features of multi-axis robotic motion control, integrated servo motor drives, network communications, and machine vision interface, the Guidance 1400A series includes a dedicated MCP interface for connecting to remote IO, as well as motor drives capable of driving 200W and 100W motors simultaneously. The user interface is based on a web server that resides in the Guidance 1400A, allowing the controller to be accessed from other locations. The software includes a set of motion commands, machine kinematics, continuous path motion planner and trajectory generator, and an optional machine vision package that can execute in a networked PC. The vision software also contains measurement tools and a patented object locator that can find multiple instances of parts in an orientation.

EtherCAT Communication-Enabled Drive

The IDM680 Intelligent Servo Drive from Technosoft (Canton, MI) comes equipped with a CANopen, or EtherCAT communication interface, and combines motion controller, drive, and PLC functionality in one unit. The IDM680 operates either as a standard EtherCAT slave using a CANopen over EtherCAT (CoE) protocol, or it can be programmed to execute complex motion programs directly at drive level, using the built-in motion controller and EasyMotion Studio platform. The EasyMotion Studio also automatically generates TML code instructions. The drive is suitable for the operation of brushless, DC, or linear motors up to 640 W continuous/ 1.3 kW peak voltages, and is equipped with various sensors: digital and linear Halls, SSI, EnDAT, BiSS, sine/cosine incremental encoders, and resolver. PC/PLC motion libraries are available for the drive's industrial integration.

Food and Beverage Sensors

A series of food and beverage sensor products from AutomationDirect (Cumming, GA) includes AC and DC proximity, photoelectric sensors and quick-disconnect sensor cables. Compliant with the IP69K standard, the sensors withstand washdown conditions up to 212 °F and are made from FDAcertified material. The PFM 12 mm and PFK 18 mm proximity sensors have shielded or unshielded stainless steel housings and M12 quick-disconnect plug with gold-plated pins. The PFM series has a sensing range of 4-8 mm, while the PFK line has an 8-12 mm range. Models are available in a choice of 10-30 VDC PNP or NPN transistor outputs, and normally-open or complementary output configurations. Two series of 18 mm food and beverage photoelectric sensors are also available in 30 models and four styles: diffuse, polarized reflective, through-beam, and retro-reflective (for transparent objects); sensors are equipped with LED status indicators. IP69K-rated cables have also been released, and industry standard axial and right-angle M12 or half-inch micro connectors with open leads are available in 5- and 10-meter lengths.

Non-Contact 3D Digitizer

The Konica Minolta RANGE 7 non-contact 3D measurement camera from Konica Minolta Sensing Americas, Ramsey, NJ, has a scan range of 450-800 mm, an accuracy of ±40 μm, and a scanning input time of approximately 2 seconds per shot. The camera and its controller can be integrated into a single body weighing approximately 6.7 kg. In addition, the RANGE 7, which has a 1.31 megapixel CMOS sensor, features a 3D preview function and interchangeable TELE and WIDE lenses. A multi-focus mode also automatically shifts the focus position to provide three-dimensional measurement data, and an auto-focus function adjusts to a user’s specified points. User calibration can be performed with an optional, movable stand.
