Working Principle
Three-phase high-voltage AC power passes EMC filter and full-bridge rectifier to form high-voltage DC bus. High-power IGBT module outputs three-phase adjustable frequency sine wave current to heavy-duty servo motor under DSP vector control. Multi-turn absolute encoder transmits rotor position data to control chip for ultra-precise position closed-loop control. During multi-drive shared DC bus configuration, regenerative braking energy from decelerating motors is shared among accelerating motors to reduce power grid energy consumption. STO safety circuit directly cuts IGBT drive signals independent of main control chip to meet machine safety standard requirements.

- Regularly clean fan dust filter every 2 months in workshop environments with metal dust
- Avoid frequent emergency stop operation exceeding 10 times per minute to prevent braking resistor overheating
- When multiple drives share DC bus, configure power balance parameters via Kollmorgen WorkBench software
- Do not modify internal safety STO circuit wiring, will invalidate PLd SIL2 safety certification
