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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
