Working Principle:
The inverter converts AC input to DC through a three-phase rectifier, stores energy in the DC bus capacitors, and synthesizes a variable-frequency PWM output through IGBT switching. The FOC algorithm uses coordinate transformation to independently regulate the motor’s magnetic flux and electromagnetic torque, achieving high-efficiency operation across the full speed range. The PID controller processes analog or digital feedback signals to maintain precise process variable regulation.
Installation Requirements:
- Install in a dry, ventilated environment free of corrosive gases
- Ensure adequate ventilation around the heat sink
- Use shielded motor and power cables with proper grounding
- Connect braking resistor when dynamic braking is required
- Verify input voltage stability within ±15% tolerance
- Anti-corrosion coating recommended for chemical and paper industry installations
Usage Notes:
- Perform motor initialization when connecting a new motor
- Configure PID parameters according to the specific process requirements
- Monitor fault codes through the integrated display or MOVITOOLS software
- The modular design allows independent replacement of power unit, control board, or fan without full unit replacement
- Verify braking resistor impedance matches the drive specifications
