Stober FAS4028 Posidrive Servo Drive

The Stober FAS4028 Posidrive Servo Drive is a servo motor control device in the Stober Posidrive family, delivering 2 KVA apparent power and 1.5 kW of rated output. It is used in industrial automation to regulate speed, torque, and position of servo motors, enabling precise, repeatable motion in automated systems. The model FAS4028 identifies this unit within the Posidrive lineup and specifies its power and control configuration. The 2 KVA / 1.5 kW rating communicates the electrical capacity available to drive a motor load, helping engineers match motors and load profiles to performance needs. As a component of a servo motor system, the FAS4028 supports controlled motion for applications requiring reliable servo performance in automation environments. Identifying and integrating this drive within a control scheme supports accurate timing, synchronization, and repeatable positioning for motion-critical tasks.
