new multi-axis drive controller, the CU320-2, incorporates current, velocity
and positioning loops for several axes using one processor rather than
individual processors for each drive.
S120 drive system utilizes the CU320-2 as the brains for the drive power
components and can be mounted in a separate cabinet for easy access and
protection against arc flash hazards. Since the CU320-2 can run Sinamics S120
drives in servo, vector or V/Hz control methods, all applications can
standardize on this single offering regardless of the motor type or performance
requirement. Using the Drive CLiQ interface, the CU320-2 control unit is able
to read all the nameplates of the Sinamics S120 drive components, including
motors, making the system setup plug-and-play, and reducing set-up time and eliminating
parameterization errors. The CU320-2 also contains the I/O and interfaces for
the drive system in one central unit.
the CU320-2 it is possible to control either six servo or vector axes, or 12
V/Hz axes from a single control unit. Increased usability of the CU320-2
includes an Ethernet programming port and 1 GB compact Flash for storing drive
parameters, firmware and project documentation. The cost savings of using a
multi-axis controller instead of individual drive control cards is substantial
on drive systems using three or more drives. Having all the parameters and
firmware on the compact Flash card in the CU320-2 means that any component can
be replaced without having to program the new component.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
