Minarik DLC300 - Digi-Lok Converter Simple Type: Motor Controller

Minarik Models DLC300 and DLC400 Digi-Lok Converters are used with conventional analog speed controls to produce closed-loop digital systems capable of controlling motor speed precisely and with excellent reproducibility. The Digi-Lok Converter (DLC) receives the feedback signal generated by a sensor that monitors a rotating element driven by the motor. The sensor assembly can be a magnetic pickup with ferromagnetic gear, or a NPN-type optical encoder or inductive proximity switch, or a Hall effect sensor with magnetic wheel. An important distinction exists between any Digi-Lok Converter system and a conventional servo drive. The Digi-Lok Converter reads a velocity-dependent feedback signal and corrects its output to bring the motor back to its set speed. The Digi-Lok Converter will not compensate for any positioning errors caused by very minor speed fluctuation. Industrial applications for Digi-Lok® Converter control systems include many within the food processing, chemical, and pharmaceutical industries, for example. Blending, mixing, grinding, pumping, and other such processes often require strict repeatability to ensure product uniformity. The digital speed-setting feature of the Digi-Lok Converter and the closed-loop design provide that reliability and reproducibility.
