Made to keep up with higher reliability and smaller space demands, this new series has a protection circuit against the load short or open operation, and a space-saving built-in resistor for current sense. The peripheral circuit design is simpler with a common interface signal and series pin compatibility. The series is more reliable with a built-in motor coil, short and open-circuit protection, and varied lout lineout (1 A, 1.5 A, 2 A, 3 A). Clock-in topology reduces control signal wire and micro-computer load, with ICs built into a logic circuit to control excitation switching and D/A converter. The series has both microstep type and full/half-step type. Unlike other motor drive series, the SLA7070M is designed to make pin alignments and interface specification compatible.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
With strong marketplace demand for qualified engineers across the board that currently outstrips the available supply, there may never be a better time for engineers and project managers to advance their careers and salaries. Whether those moves are successful in the short-term and long-term is likely to depend on how the transition from one job to the next is handled.
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.
