The
Beckhoff I/O system is an I/O solution for highly-dynamic positioning tasks
onto the market. The EL7201
servo terminal with resolver interfaces features a compact design, while
offering high servo-performance. The integrated fast control technology, with a field-oriented current and PI speed control, supports highly dynamic positioning tasks. Apart from the
direct connection of motor and resolver, the connection of a motor holding
brake is also possible.
Permanent
magnet synchronous motors with a rated current of up to 4A can be connected as loads. The monitoring of numerous parameters, such as
overvoltage and undervoltage, overcurrent, terminal temperature or motor load,
offers maximum operational reliability. Modern power semiconductors guarantee
minimum power loss and enable feedback into the DC-Link when braking.
The servo
terminal is fully integrated into the Beckhoff automation software TwinCAT,
enabling convenient parameterisation. In the case of third-party masters,
parameterisation takes place via the CAN over EtherCAT profile (CoE).
The servo
terminals cover a broad range of positioning tasks: from packaging and assembly
machines to small robots. With the EL7201 servo terminal, the range of servo drives from
Beckhoff becomes even more finely scalable: from the miniature servo drive up
to 200W in the EtherCAT Terminal format to the AX5000 Servo Drive with 118 kW.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
