Kollmorgen 65WKS-M310/12

Product Description:​
A legacy analog brushless servo amplifier designed to drive Kollmorgen SMR-series permanent magnet synchronous servo motors in torque or speed control mode. It receives ±10 V analog command signals and requires an external isolating transformer on the three-phase mains supply. This is a 4-quadrant regenerative drive with an integrated brake chopper circuit.
