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.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
