Kollmorgen SR20200-000000
Model Series: S200 Series Digital Servo Amplifiers
Product Introduction:
The SR20200-000000 is a 2-axis digital servo drive from the S200 product family. It provides sinusoidal commutation control for brushless servo motors with integrated current regulation, velocity loop, and position loop capabilities. The “000000” suffix indicates a standard configuration with no optional modules installed.
