The controller is the first in Galil's new Accelera Series, the fifth generation of its motion controllers. It can take encoder inputs of up to 22 MHz, servo update rates as low as 24 microseconds per axis, and command processing times as low as 40 microseconds for application programs with its 32-bit Risc-based clock multiplying processor with DSP functionality. The new series is designed to handle the faster command processing and servo-loop update times needed in applications like the ones for low-inertia, high bandwidth motors. It also has the speed to work with high-resolution feedback sensors. In step motor applications, the new controller doubles the frequency of the stepper pulse output with a maximum pulse rate of 6 MHz. It is available in 1 to 8 axis formats, with each axis configurable for stepper or servo motor operation, so users can mix and match motor types in an application. Users can convert from an older Galil product to the new controllers, which use the same programming language and 100-pin SCSI connectors. The DMC-18x6 also has servo loop features such as advance PIC compensation, velocity and acceleration feedforward, integrator limits, notch filter, low-pass filter, backlash compensation, expanded memory for variables, arrays, storing application programs, multitasking up to eight programs at once with fast I/O processing to synchronize with external events, various modes of motion like point-to-point positioning, position tracking, jogging, linear and circular interpolation, contouring, electronic gearing and ECAM, and advanced commands for coordinated motion, such as ellipse scaling, slow-down around corners, infinite segment feed and feedrate override.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
