STOBER SDS4021 POSIDYN Servo Drive

Feature & Principle

It is a full-digital servo drive developed by German STOBER. It receives command signals from PLC or motion controller, outputs precise three-phase power to servo motor. It supports encoder feedback for closed-loop high-precision positioning. Built-in motion control function block, no need for upper controller for simple cam and synchronization tasks. It has complete overcurrent, overvoltage, overheat, encoder fault protection. Multiple fieldbus options for networking with automation host.
