Built-in high-speed closed-loop voltage stabilization control, response time <1ms, even when multiple axes are simultaneously accelerating and decelerating, or the load undergoes drastic changes, the bus voltage fluctuation is <±3V, completely eliminating voltage instability-induced servo jitter, positioning deviation, and synchronization failure problems, ensuring ultra-large production lines to operate stably and accurately around the clock.

3.2 Four-quadrant active energy feedback (ultimate energy saving)

Equipped with the latest four-quadrant active feedback algorithm, the regenerated electrical energy generated during servo motor deceleration, braking, heavy object lowering, and inertial shutdown is no longer consumed through resistance heating, but is inverted, phase calibration, and grid synchronization by the module, and then 100% fed back to the industrial grid for recycling. Feedback efficiency ≥97%, in lifting, lifting, machine tools, mechanical hands, and other frequent start-stop, large inertia braking scenarios, the comprehensive energy saving rate reaches 30%~40%, while significantly reducing equipment heat generation, reducing workshop cooling load, and extending component lifespan, with long-term usage economic benefits being huge.
