Kollmorgen Servostar 20A Servo Drive

Feature & Principle

It is Kollmorgen SERVOSTAR 620 series full digital servo amplifier with 20A continuous rated current. It executes high-speed closed-loop control for torque, speed and position. It supports multiple feedback signals including resolver, incremental encoder and SFD. Built-in auto-tuning function simplifies load matching, integrated brake chopper and DC bus sharing function for multi-axis system. This model is discontinued and widely used for maintenance replacement of old CNC machines, packaging equipment and gantry automation.
