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.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
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.
