IndraDrive products from Bosch-Rexroth, with Safety-on-Board, provide reaction times which the company says are 400 times faster than conventional solutions that use contactors to produce a safe stop.
Safety functions can be selected directly at the drive and include functions to achieve safe standstill, safe operational stop, reduced velocity (speed), limited increment, direction of movement, limited absolute position and safe control of protective door. Rexroth's Safe Motion technology is certified according to EN 954-1, Category 3. The IndraDrive with Safety-on-Board is designed in accordance with EN61508 and EN954-1 SIL3 standards.
The drive also offers I/O for the safeguarding logic needed to interface to safety gates, panel switches and interlock switches. The drive units, available as servo or vector, cover an output spectrum from 1.5 to 120 kW. For more information on IndraDrive products, go to http://rbi.ims.ca/4930-533.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
