High Precision AC Servo Motor Drive – Industrial Motion Control Engineering Solutions

Product Definition (Engineering View)

The High Precision AC Servo Motor Drive (T3A / T3L Series) is a fully digital motion control device designed to regulate torque, speed, and position of AC servo motors with high accuracy. It integrates vector control algorithms and real-time feedback processing to ensure stable performance under high dynamic load conditions.

Working Principle

The servo drive receives command signals from PLC, CNC controller, or motion controller, then compares them with feedback signals from the encoder. The error is processed by a high-speed digital controller, which adjusts output voltage and frequency to precisely control motor behavior.
