Kollmorgen 65WKS-M310/22

Product Introduction:​
The 65WKS-M310/22 is a Kollmorgen S300 (SERVOSTAR 300) series digital servo amplifier, also marketed as SERVOSTAR 310. It is an earlier-generation drive preceding the AKD series but still widely used in legacy installations. “65WKS” is the Indramat/Kollmorgen legacy naming; “M310” = 310 model (10 A continuous), “/22” = firmware/option version.
