KOLLMORGEN SERVOSTAR 620-AS Digital AC Servo Amplifier – SERVOSTAR Series
When a servo drive fails on the production floor, everything stops. Robotic arms freeze mid-cycle, CNC axes lose position, and conveyor systems halt — costing manufacturers thousands of dollars per hour in unplanned downtime. The KOLLMORGEN SERVOSTAR 620-AS is the precision motion control component that keeps these critical systems running without interruption. Engineered for demanding industrial environments, this digital AC servo amplifier delivers the closed-loop performance that modern automation cannot afford to be without.
Within the KOLLMORGEN SERVOSTAR series — one of the most trusted servo drive families in global industrial automation — the 620-AS variant occupies a high-performance tier, combining advanced digital signal processing with robust power handling. KOLLMORGEN’s SERVOSTAR platform has been deployed across aerospace, semiconductor manufacturing, packaging, and precision machining industries worldwide, earning a reputation for reliability and seamless integration with leading motion controllers and PLCs.
