Platform Concept of Sensorless Drive Controller SDC
The mechanical design of ABM Sensorless Drive Controller SDC allows flexible adaptation to complex drive demands in stand-alone as well as multi-axis operations. Drive related functions including sensorless control are concentrated on one circuit board (power unit). Systems related control functions such as serial interfaces to superior control- and operating levels are located on an additional circuit board (control unit). This board can independently control up to eight power units in a multi drive set up. Data transfer between boards is handled by an internal communication bus (Syncbus).
