Servoland SVFH8-H3-DSP*ANI Servo Drive

The Servoland SVFH8-H3-DSP*ANI is a high‑performance digital servo drive incorporating a dedicated digital signal processor (DSP) for fast, precise control of brushless AC and DC servo motors. It is designed for demanding motion applications requiring high bandwidth, torque stability, and advanced communication.

Technical Specifications

Power input is 200‑240 V AC single‑phase or three‑phase, with a continuous output current of 8 A and peak current of 16 A. The drive includes built‑in EMC filtering, regenerative braking transistor, and an integrated power supply for control logic. Communication interfaces include CANopen, EtherCAT, and RS‑232/485 for configuration and real‑time control.
