Kollmorgen S70302-PBNAS2-US
Product Introduction: The S700 is Kollmorgen’s next-generation digital servo drive succeeding the S600. It features high-bandwidth control loops, extensive feedback support, and modular fieldbus interfaces. The “PB” indicates Profibus DP slave interface; “NAS2” denotes specific I/O & auxiliary configuration; “US” = 120/240 V AC line voltage rating and UL/cUL listing.
