Working Principle: Three‑phase AC input passes internal rectifier to generate DC bus voltage. High‑current IGBT inverter converts DC bus to adjustable‑frequency adjustable‑amplitude three‑phase AC output to drive motor. Motor position and velocity feedback signal feeds back to drive control board. Digital processor executes closed‑loop position, velocity and torque control algorithm according to host command. Dual‑channel STO hardware circuit cuts IGBT gate drive signal to remove motor torque under safety trigger condition. Integrated brake chopper consumes regenerative energy produced by heavy‑load deceleration to stabilize DC bus voltage.
