Designed as a stand-alone controller for moderate to high-performance applications, the Ensemble Epaq's motion control capabilities include point-to-point, linear and circular interpolation, electronic gearing, and velocity profiling. The unit's processing power and high-performance capabilities come from a 225 MHz double precision, floating-point DSP. An optional single-axis Position Synchronized Output (PSO) offers high-speed position latching capability. To simplify generating motion commands, the unit has an intuitive user interface and does not use cryptic commands. Standard interfaces include RS-232, joystick, Ethernet and USB 2.0 ports. Each axis of the Ensemble Epaq I/O has a 16-bit ±10V dc analog input, dedicated home marker input, over-travel limits, Hall inputs for motor commutation, and Estop input. Targeting applications from basic laboratory experimentation and general purpose positioning to advanced OEM systems, the unit drives and controls linear or rotary brushless, dc brush servo, and microstepping motors.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
