Working Principle:
The inverter converts AC input to DC via a three-phase rectifier, stores energy in DC bus capacitors, and synthesizes variable-frequency PWM output through IGBT switching. VFC mode operates without encoder feedback using an internal motor model; CFC mode uses encoder feedback for closed-loop current vector control with real-time flux and torque decoupling.
Installation Requirements:
- Vertical cabinet mounting with adequate ventilation
- Minimum clearance above and below for airflow
- Shielded power and motor cables with 360° grounding
- Phase sequence matching U-V-W terminals
- Braking resistor connection for dynamic braking
- Ambient temperature 0°C to +50°C
- Encoder cable connection for CFC mode
- PROFIBUS-DP cable to X30
Usage Precautions:
- Execute motor initialization after motor connection
- Commission via MOVITOOLS MotionStudio software
- Verify supply voltage within ±10% tolerance
- Never connect/disconnect motor cables under power
- Monitor fault codes via LED or MOVITOOLS
- Regular heat sink cleaning
- Grounding resistance below 1 Ω
- Wait 5 minutes after power-off before maintenance
- Derate 20% at 500V supply
