Kollmorgen SR1000-2G204C
Product Type: Single-axis brushless servo amplifier
Product Introduction:
SR1000-2G204C is a member of Kollmorgen’s older SR/S300/S600 servo drive lineage (commercialized before AKD took over mid-power slots). It provides closed-loop current, speed, and position control for synchronous AC servo motors such as AKM or Goldline.
