Kollmorgen S20660-SRS

Product Introduction:​
The S200 series is Kollmorgen’s first fully digital industrial servo drive family featuring an 800 Hz velocity loop bandwidth. The S20660-SRS is a compact single-axis drive rated 6 A RMS continuous / 18 A RMS peak, equipped with a SynqNet motion bus interface for distributed multi-axis control. It supports plug-and-play commissioning via the electronic motor nameplate (Smart Feedback Device) and is intended for precision indexing, packaging, semiconductor, and machine tool applications.
